Omega Centauri from Anza, CA

I had gone out to my clubs dark site for several nights to work on a widefield mosaic of the Orion/Gemini area, once that set I had some free time to shot a few objects I’ve always wanted to go for. I noticed Omega Centauri was barely above the mountains to the south around 1 am so I pointed the 6″ and snapped away. Seeing was excellent that night so even though it was very very low the color wasn’t too washed out.

Markarian’s Chain

This is always a fun target, good test to see how deep I can push the new camera. Pretty damn deep it looks like! You can easily pick out M 84, Ic 3303, Ngc 4387, Ngc 4388, Ngc 4402 , M 86, Ngc 4407, Ngc 4425, Ngc 4435, Ngc 4438, Ngc 4461, Ngc 4473, Ngc 4477, Ngc 4458, M86, M84, Ic 3393 and Ngc 4479. I need to find some reference material to see how deep I’m getting. I also plan on shooting this area again next month in a mosaic from Tierra Del Sol which is a bit darker than Anza.

M78 – Reflection Nebula in Orion

This sure was challenging! Two out of the three nights I arrived late and couldn’t start work until Orion well into the light pollution of north San Diego county. Taking stuff out of the car, polar alignment, mount alignment, focus and framing really eat up my dark sky time but I don’t have much of a choice when I can’t leave work until five and the dark site is three hours away in traffic. Still worth it!

But because it was setting I had a lot of problems with gradients, very tough to get rid of but I think I did a decent job. I must say, my new 1100d is a fantastic camera! I modified it three days after picking it up.

Processing was a challenge because of the gradients. Pixinsight’s DBE tool got quite a workout but I was careful not to get rid of any of the faint dust and gas that IS actually there. I plan on dishing myself some more punishments by creating a mosaic of this region later in March for an art show I was invited to participate in.

M31 Andromeda Galaxy Mosaic

This one was very very tough. I had some very bad gradients from light pollution, upper atmosphere clouds and a red LED that somehow leaked light into the scope causing some nasty images in the core frame. I’m not sure if I’m happy with the colors or not so I may come back to this one shortly.

More from Joshua Tree

Sitting at the airport, flight to SFO is delayed, processing some leftover images from last weekend.

Here is the constellation Orion with some clouds in front of it.

Here is a the center of Cygnus with a 70mm lens I found at the swap meet for $15

Still more to come from this session.

Equiptment pics

I can’t remember if I’ve posted pictures of my setup but here it is. I’m testing everything out tonight before I spend a weekend in Joshua Tree, it’s been awhile since I’ve gotten out to the desert and I didn’t want to forget anything.
