Fall 2014

In late October, I sent the T2i to Gary Honis to have its stock IR filter removed and replaced with clear Astrodon glass. This leaves the camera sensor open to receive the full spectrum of light, making it much more sensitive to the pink glow of hydrogen gas in interstellar space.

I also continued to use the Starshoot Pro in combination with the T2i, but mostly stuck with the 6" Newt, except where noted.

NGC 891

A spiral galaxy in Andromeda, seen edge-on.

This image is comprised of 32, 120-second sub-exposures taken through the 6" Newt with the T2i (an adapter allows it to connected directly to the scope through the focuser.

NGC 7635 -- The Bubble Nebula 

26, 120-second sub-exposures taken with the DSLR through the 6" Newt were stacked to create this image.

NGC 7789

This is a large open cluster in Cassiopeia.

14, 120-second exposures taken with the unmodified T2i through the 6" Newt were stacked to create this image.

M103

Another, smaller open star cluster in Cassiopeia.

18, 120-second exposures taken through the 6" Newt with the unmodified T2i.

M52

A larger open star cluster in Cassiopeia.

16, 120-second sub-exposures were taken with the unmodified T2i through the 6" Newt to make this image.

M1 -- The Crab Nebula

The remnants of a supernova that occurred more than 1,000 years ago in the constellation Taurus.

This image is composed of 17, 180-second sub-exposures taken through the 8" SCT with the Starshoot Pro.

NGC 1499 -- The California Nebula

So called because of its shape, which resembles the Golden State.

63, 120-second sub-exposures taken with the modified T2i through a 250mm lens were stacked for this image.
