Washed out Lyrids...

Hi All,

Today early morning one of the famous Meteor shower "Lyrid" was peaked, I planned yesterday to wake-up early in the morning by 3:00 AM and try to get some photos, but was bit lazy & woke up at 4:45 AM and ran to terrace with DSLR and Tripod, And what a sky !!! with little clouds and all washed out with bright moon light, i was expecting it but moon was already near the west horizon still 30 degree above it and i thought i might get East bit darker but all sky was very bright, Mixed with light pollution from City the pics look all red-gray.

So i switched to Mono Chrome mode which at least gives some natural look to photos, with lens set at 18mm, ISO 1600 & Aperture F4.5 i started taking series of photos at 30 sec exposures hoping to catch at least one meteor.

Mean while I was staring in bright sky in hope of catching meteors visually. I had a better experience of catching meteors visually in other part of the sky than where my camera is pointing :D But my efforts was in vain I could not spot a single meteor till East Sky started glowing as sunrise nearing. may be i was late....

I took some 37 snaps till 6:00 AM and returned to continue remaining sleep. After I woke up again at 8:00 I downloaded photos on computer, started analyzing each photo carefully by converting them in negative, and Suddenly I saw one steak on one of the photo which i took of Moon in clouds, Wow a small meteor in Bright Sky !!!

I took this photo to capture beautiful Moon Rays from clouds and turn out to be one with Meteor too.. And that to in just 6 sec exposure !!! - May be that what they call "at Wrong Time at Wrong Place" :D

I am bit suspecius about its origin is Lyrid, but nevertheless I caught one !!!

The beautiful moon-rays and Scorpius... the meteor is about one o'clock position to the pipe... Click on photo to view large size in new window...


This is cropped close up of Meteor part of above photo, it is just to the left of Antares of Scorpio...

Victims of Light Pollution....

Hi All,

On Saturday 5-Apr-08, I and Nilesh we planned for Astrophoto session from my home at Thane. Nilesh come from Pune with his C9.25 and HX9 CCD cam. We were hoping to set it up on LXD75.

But it did not go on it as we did not have dovetail plate for it :(

Anyways we decided to use my AT66 (focal length 400mm) and Mead DSI color for photography. Nilesh fixed RoboFocuser on AT66. That reduced our great efforts for focusing Mead DSI. as those who used any CCD cam knows what a pain to focus it... Using robofocus its just 5min job to get perfect focus !!!

We Started at around 12 and setup was ready to use by 1:00 as we spent some time for visual use too...

Then come the next frustration act searching for targets in light polluted sky and that too in Leo / Virgo sky where there are many galaxies, which we do avoid as being beginner...

And further to push us hard we don't have finder on AT66, as it is very small scope... finding galaxies with small scope was pain ( even M4 was not visible when it was 40 degrees above horizon... Its Glow from Mumbai and Thane....)

After searching fruitless Nilesh advised remove cam and use eyepiece to find targets and then use cam... This worked and we got first target M51.. thoough it was not visible in Scope we know for sure where it is so we set it using eyepiece and then put DSI back. the focusing was not an issue now. and took 30 sec preview :D wow the galaxy was just near the corner. we center it using 15sec expos... and then started actual shot.. we Set Cam at Monochrome Mode as we found the color mode after subtracting dark frame causing some false color.. and set exposure to 30sec...

The best feature of Meade DSI it auto selects the good frames and stacks based on track stars provided to it.. this helps to avoid tracking errors...

We stacked around 45 frames and the result is.....

M51 : Stack of 45x30s


Later we tried following objects but the extream light pollution caused to drop out many frames in Auto Stacking and the resultant were not so good.... I hope i can upload maually processed images some where in this week, as I have all individual images which were taken during auto stacking....

M4


M8 - Lagoon Nebula


M22 - In Color

Lunar Eclipse of Feb 20 2008

Hi All,

here are my photos of Lunar Eclipse of February 20, 2008. This eclipse was not visible from INDIA, but i was lucky as i am currently in New Jersey, US.

The conditions were very cloudy initially but as eclipse progressed the sky was also cleared and almost clear around moon during totality.

I used my AT66 ED refractor at prime focus (@400mm) and Canon Digital Rebel XTi camera.

1. Patial Phase @ 9:26 PM EST | 1/60sec | f/6 | ISO-100


2. Partial Phase overexposed to show shadowed moon @ 9:45 PM EST | 2.5sec | f/6 | ISO-100



3. Totality just began @ 10:03 PM EST | 5sec | f/6 | ISO-100


5. Mid Totality @ 10:26 PM EST | 5sec | f/6 | ISO-100


6. Saturn - Regulus & Eclipsed Moon @ 10:40 PM EST | Canon 75-300mm lens @ 75mm | 3.2sec | f/7.1 | ISO-100 | Tripod mounted


I will post details of photos including exposure and equipment by tomorrow on my Astrophotography Blog

Mead DSI-Color - First Night Out

On Thursday 14th Feb I have received my Mead DSI-Color camera, luckily today that is Saturday the condition of sky was very good, so i planned for photography session.

Mead advertises DSI cameras are very easy to use, but on Windows VISTA there is lot of problems in using camera, I searched all forums and did not find any proper solution.

I spend Friday night and Saturday morning in installing uninstalling Autostar suite and other required software, at last camera started working...

The evening was chilling, temp was -4 -8 Celsius when i started at 7:00PM !

I setup my mount, did casual alignment, and DSI was ready for action. I first targeted brightest object available MOON, but with focal length of 400mm the results were not acceptable, Moon was not sharp enough :( the Magic Eye function of Autostar software did not help much !!!!

Then i turned scope to M42(my test object) and spend some 10min in focusing cam, i realized that the most critical part of any astrophotos is focus!!!

As soon as i got reasonable focus, i took dark frames(It is very important to take dark frames for Deep sky photos, DSI dose have some hot pixels that can't be eliminated without Dark Frames.

Once dark frames are completed i started takings snaps of nebula, I started with 5sec and pushed till 2mins. unfortunately my 1 min and 2mins snaps were not saved due to software problem or may be due to my poor understanding of camera !!!

i got some so so pics with exposure of 5x8, 10x7, 30x5 sec exposures...

I processed those and combined in photoshop, the result is not satisfactory but if i would not have those lost images with exposure of 1 min and 2 min (taken for Luminance) then it would have been excellent image :)

Uff... Astrophotography is cruel, lessons are always learnt hard way !!!

during this session i also notice the LXD 75 mount works great even though the scope aligned causally it tracked objects very well, even 2min exposures were excellent with no trails or jumping in star image... Cool thing [:)]

here is photo of M2 taken with DSI. The result is not great but it is my first attempt with using Meade DSI, and image is not bad; considering heavy lightg pollution of New York...[:)]




Hope very soon i get clear sky !!!

AstroTech 66 ED in Action

After wait of almost 20days, at last i got clear sky on 10th Feb. The sky condition was very good but temperature was chilling -15 Celsius !!!

I setup mount and scope and attached My Camera at prime focus. Now my scope is working as 400mm Tele lens...

I roughly aligned mount using polar finder and centered Moon, focused and bingo !!!

Got few nice images of moon....


using Moon as focusing aid, i turned scope to My Favorite M42...
I took series of photos from 5sec to 30sec at 100 ISO and 800 ISO. photos taken at ISO 100 was almost useless due to heavy light pollution, and at 800 ISO sky background turned red !!!

Also the images are soft-focused as focus shifted while adjusting telescope :(

I combined and processed images taken at 800 ISO and achived acceptable image of M42.

here is the result processed and cropped...



Following are the unprocessed crops from original images which are combined in above processed image..



Now weather here for next 15 days is expected to be bad :( and wait for clear night started again...

The First Light....

After waiting 5 days for clear sky, at last today i got chance to use my new setup.
also just yesterday i received my Mead LPI camera too.. So its good time to test all things together.

I carried everything to terrace with help of Mandar, and setup mount Mead LXD75 and AstroTech 66ED refractor... and without counter weight !!! even with single counter weight i cant balance scope, it just too light for 10LBs counter weight....

It was dammn chilling... -4 Celsius !!!

The sky was clear but very bright due to glow from NewY ork Manhattan and Jersey City lights.... the Orion Nebula was hardly visible in telescope!!!

I setup mount with polar finder as close as possible to north pole.... and set mount for easy align method... It set Capella first and as soon i set it manually and hit enter on Autostar keypad it moved to next star Dhube... Telescope swelled and in low power field the Dhube was right there...alignment complete !!!

Its time to test GoTo capability, object i asked to set is MARs and goto scope did it right at first time.... mars was just below the center of field... Not BAD at all...

I tried to search Comet Holmes but cant find it due to bright sky, next i setup M45 and used Mead LPI to capture pics but the Field of frame is not enough so i switched to All Time favorite of First Time Astro-Graphers... ORION NEBULA...

I used Mead LPI on 400mm AT66ED...

here is the result of First attempt...stack of 3 pics 5, 8 and 11 sec.... combined using Registax.... As LPI is not meant for deepsky photos i was not expecting something deferent than what i got...

But still its my first Pic on owned setup :)

Comet 17/P Holmes - Outburst

Hi All,


Till October 23, 2007 Comet Holmes was fibble small dot of magnitude 17 that is almost 25,000 times fainter than faintest star we can see in clear dark sky with unaided eyes. But on 24th Comet suddenly brightened to 7th magnitude and with in few hours it reached to magnitude 3, almost 400,000 times increase in brightness !!!


Now comet is visible to naked eye like a star in costallation Perseus.


About Comet Holmes...


Comet Holmes was discovered by Amateur astronomer Edwin Holmes in 1892. While he was observing Andromeda Galaxy comet was discoved, and then comet reached to 4th magnitude.
It fainted and again in Jaunary 1893 it brightened 100 fold.


It seems to be the outbursting is the nature of Comet Holmes.


The comet orbits the Sun once in 7 years at a distance of about 200 million miles (compared to Earth’s 93-million-mile orbit). It was observed again in 1899 and 1906But after that comet was not seen for almost 60 years!!! Based on a calculations by Marsden, the comet was recovered in 1964.


No body knows exact reason for these OutBursts !!!

Currently the comet is at magnitude ~2.5 and becomes small fuzzy ball in telescope with bright starlike necleaus. we are not sure how long comet will remain visible....



Here is my sketch of Comet on October 25, 2007

These photographs are taken using mobile camera over my 4" Newtonian telescope. The Quality of photos is very poor but it gives you idea how bright the comet is, to being captured so easily using mobile...




======================

And here is the picture of Comet by R. Richins on October 24, 2007. This is how comet look in small telescope...

2007 Aurigid Meteor Shower Photos

Hi all,

We all know on 1st September 2007, there was rare Meteor Shower "Aurigid". It was indeed spectacular, and unfortunately nothing was seen from India.

Here are some of the photos taken by various observers...

Comet C/2006 VZ13 ( LINEAR ) is here

Hi Friends,
Comet VZ13 Linear is now at its brightest, software predicts at about 9.8-9.7 mag but actual observed magnitude is 7.8. But as we know Its Mansoon time and here and sky is almost cloudy all day and night. But the ray of hope is Sattelite picture of Indian sub-continet shows Clouds are vanishing so in few days we might get clear sky. So let get prepared to watch this bright comet.


Following are the map prepared from software Cartes du Ciel (Mine Favourate). Stars are down to 9th Magnitude and small circle in the center of each image is 1 degree circle.

Postion is plotted at the interval of 1 day at 20:00 hrs when comet will be at zenith most of the days.

Do post your observation at this blog or on Our Group..

Best of luck and have a clear sky

Moon Setting in Yevur Hills

Lunar Observation Session on May 27

Before the mansoon starts we planned observation session on May 26, 2007. We planned to go away from Mumbai to Murbad area for observation. But at Last moment plan failed as we realize that moon will be in sky till 2:45 am leaving us very short period of time for DSO, and that to in cloudy sky. So alternately we planned Moon Observation from comfort of our Home. And here are some of the observations made on May 27, 2007 (:D – Not on 26).

I have decided to do some sketching of Moon, aiming at some domes & rills. Using 4” telescope I targeted Moon at around 11:00 pm, but unfortunatly my all eyepiece combinations provided with only 160X L. And “Jale Pe Namak” sky condition was so good that I could have cranked to 300X easily with 4” !!!!

Well due to lack of Magnification I could not observe Domes as Planned and at somewhat low magnification Sketching is too difficult so I changed my plans from sketching to Photographing :)

Using 4X Barlow coupled with 25mm Eyepiece I used my Mobile Camera, I took some snaps by painstakingly centering tiny Mobile Camera lens over small eyepiece eye lens. There is lot of shaky images :(. So I decided to video shoot using mobile, I know that it will give me small image size but still it is the best thing I can do to get better results as I can choose good frames from 1000s of available. Here to my surprise I do get some acceptable results, If Camera would have mounted on Eyepiece instead of Hand held it would be much better that what I got…

Here are what I got...
==========================================
1. Copernicus View One 2 unprocessed Frames .


===================================================
2. Copernicus View Two – 4 unprocessed Frames .


===================================================
3. Gassendi - 2 unprocessed Frames .


===================================================
4. J. Herschel – I have seen this amazing crater for the first Time, It surprising that I have never come across this big crater before. May be the conditions on May 27 were favorable at crater was rightly placed at terminator. The details visible in telescope were really beautiful as you can guess from this low resolution photo.


===================================================
5. Tyco region - The bright white one is Tyco – Don’t think I have copied it from somewhere by Looking at “DIVx” watermark :D I have to convert file from 3gp format (This is the format Mobile camera captures video) to AVI so that I can extract frames using Microsoft Movie Maker.


===================================================
6. North of Tyco region


===================================================

I will try to find out Names of all prominent craters and other features and will update in my Celestial Log.

I know these photos are not of great quality and even web camera attached to telescope can produce much much better results but these are captured using very crude method and no setup at all just telescope set for visual observation and a Mobile with camera :).

I am posting these photos to make other amatures think of Astrophotography is, also as simple as using ordinary camera; and not always a very specialize stream of Photography which requires costly equipments and great skills!!! Those who have basic digital cameras can produce much better results than this.

Have a Nice Day

Mars Occultation of April 14 2007

Hi friends

Here are some of the pics of Mars Occultation on April 14, 2007 morning, taken with 4" Telescope and Mobile Camera using AFocal Method (Eyepiece and Camera lens in place).

1. 5:44 AM


2. 5:57 AM - Shivering due to Cold ??? - [:D] Just Kidding


3. 5:59 - Touch Down


4. 6:24 AM - Reappearance - faint white dot below core


5. 6:25 AM - Little more contrast but no help :(


Following Photos were taken while waiting for Mars to Reappear.

At 6:05 AM


At 6:06 AM


========================================
This one was taken on March 24, 2007 -

Moon was setting in to Trees of "Yeur Hills" at 11:44 PM. Thin Clouds and polluted horizon make it hard to achive sharp focus...



Have a Nice Time Always
Sameer :)
