Living upto expectations - Tamron 17-50 F/2.8

Dear Friends, Recently I bought new lens for my Canon 7D as a replacement of Canon kit lens. TAMRON 17-50 F/2.8 non-VC. After going through lot of reviews for replacement of kit lens, there were few options Canon 17-55 F/2.8 IS, Canon 17-40 F/4 IS, Canon 16-35 F/2.8 IS and Tamron 17-50 F/2.8. Two canon lenses were currently beyond my budget so I left with two choices Caanon 17-40 F/4 or Tamron 17-50 F/2.8. I though its better to have F/2.8 as many times we struggle with low light situations with wide angle, this is maily true for indoor shots... Also in some reviews i have read Tammy is better in sharpness than Canon 17-40. So despite having dis-advantage of APS-C format lens I decided to get Tammy. Being always felt bad about low quality of Canon Kit Lens, Canon 70-200 F/4 use to live on my Canon 7D all time. Once I receive Tammy the things changed and even in situation where i would / should have used 70-200 (like in Zoom & Aquarium) I kept shooting with Tamron 17-50. There are s...

Astrophotography - Orion Nebula Core Details...

Dear Friends, On the Night of 22nd Jan me and Nilesh Desai tried to capture Beautiful Core of Orion Nebula in the Constellation of Orion. The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated south of Orion's Belt. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. The Nebula is in fact part of a much larger nebula that is known as the Orion Molecular Cloud Complex. The Orion Molecular Cloud Complex extends throughout the constellation of Orion and includes Barnard's Loop, the Horsehead Nebula, M43, M78 and the Flame Nebula. Stars are forming throughout the Orion Nebula, and due to this heat-intensive process the region is particularly prominent in the infrared. The Orion Nebula contains a very young open cluster, known as the Trapezium...

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 Eyep...
