Some bird in the backyard.

Using Canon 5D MKIII and that 70-300MM lens I am starting to hate.

London last year.

5D MKIII and the stock 105mm L lens.

Another backyard bird. It may fly next to Dixit's backyard. :)

MKIII and the not so great 70-300MM Canon lens.

(No Post Processing applied except cropping using Aperture).

I am getting the TAMRON 150-600MM just in time for the spring and a 2x Teleconverter. Stay tuned for some amazing pictures from the nearby creek and the sky.

I was reading a review that the teleconverter does not work with that lens.

I agree you should buy some good lenses for your 5D Mark-3

16-35
24-70
70-200

Are you already on waiting list, getting that Tamron lens is difficult? One of my friend has it, great lens for the dollar. This POTN thread (http://photography-on-the.net/forum/showthread.php?t=1348082&page=406) shows what this lens is capable of. I'm waiting for more reviews on Sigma 150-600 Sport to pull the trigger. I'm looking to add 150-600 range to my kit.

It's due for shipping today or tomorrow from Amazon. Looking forward to it. Meanwhile I got the Tamron 2X converter and got some shots of the moon.

T4i APS-C + Canon 70-300MM + Tamron 2X converter + f/11 (This was the widest the combo could go) + Manual focus (The combo wouldn't autofocus beyond the 70-300MM lens set to 135 -185mm). It is shot at full 600MM (300MM + 2X) and on a tripod without IS.

Once I get the Tamron 600MM I will try a full 1200MM shot on a clear sky with the 2X converter. I may still be able to get f/11 if not f/8 I think.

I think no matter what they say Ti4's APS-C with 18MP packs lot many pixels on the Moon than the FF Mark III with 22 MP. I will continue to use the T4i for Astrophotography.

Conditions: The sky was hazy. The moon was going in and out of clouds. Even when it was completely out it was still foggy around it. I will try again today. The details are not bad but have to wait for a clearer sky and a half moon to see craters and shadows better. No CA at 600MM.

Post Processing: Sharpness, Saturation and Cropping. The size of the Moon in the link below is original.

I took pictures of Jupiter and its moons. Again cloudy skies due to recent rains. The moons are not actually as huge as they appear relative to the planet. The tiny bright spots within the smaller bubbles surrounding the big red planet are actually the moons. I am thinking the halos around the moons are either due to atmospheric conditions or some lens phenomenon or something else. Focus appears to be OK.

5D MKIII, 70-300MM + 2X at 600MM. I had to use AEB. MKIII allows bracketing up to 7 shots. I chose 5 -- didn't want to use up shutter count. :)




The Orion Nebula: Canon T4i and the same lens Combo.

chaks;592837Very impressive Ambhi. If you are serious about deep sky imaging, you have to invest it in tracking system. I don't have any experience in it, currently eyeing on Skywatcher Star Adventurer tracker for wide angle astro photography. I want to capture more detail in Milky way. This tracker is reasonably priced but not much review. Skywatcher is renowned brand though.

Did a little research. While the star tracker is good for wide field photography or for lunary, planetary objects. For deep space astrophotography there is more equipment needed than a simple tracker. I have narrowed down to this list.

1. Motorized Equatorial mount telescope (Azimuth mount telescopes won't work as they don't compensate for earth's rotation).

They are not cheap. This is one of the cheapest from Orion for $1399. http://www.telescope.com/Astrophotography/Astrophotography-Telescopes/Orion-Sirius-8-EQ-G-Reflector-Telescope-with-GoTo-Controller/pc/-1/c/4/sc/19/p/24729.uts?refinementValueIds=4519

2. The above telescope automatically tracks sky objects. However the motorized tracker is only accurate for direct eye viewing. For astrophotography and long exposures however you need another device called the auto guider attached to the telescope's motorized control to guide the system for a very precise star tracking so there are no star trails.

3. You need a T ring to attach a DSLR to the eye piece:

The three together are about $1700.

Either the above or you can wait for the Hubble telescope to be put up for sale on eBay. :)

My requirement is portable one that I can use with my existing tripod for wide field astro photography mainly for milky way.

If you are really intrigued by deep space, try joining astronomy clubs near you. Usually they have monthly meetups, you can talk to those folks on their recommendations. Also you may see cool things through their telescopes.
