M78 Revisited.

This was one of the first objects I was ever proud of imaging. M78, a reflection nebula in Orion. Check out my attempt from a few years back.

 

This was also the first time in a long time I’ve done proper imaging through the telescope. It feels good to be back for a bit, I love doing timelapses and scenic photography but I think astrophotography is my true love.

Sadr Region, central Cygnus.

What a big difference the CLS filter makes, almost looks like I did hargb. I was lucky enough to get 5 hours on this target from a green zone. DSLR cooler (thanks Stephen!) helped big time with the noise.

NGC7023 – The Iris Nebula

Recently took a week off work and since I’m trying not to spend too much money right now I decided to take my vacation at my club’s dark sky site. This is the first of many images I grabbed… nice thing about having six-seven nights to image is that I have no problem focusing on one object per night and therefore get excellent data.

From http://www.astrocruise.com/milky_way/N7023_05.htm

Object Data: Lying in the western part of Cepheus, this beautiful object is a fairly unusual pure reflection nebula, caused by light from the central magnitude 7 star, SAO 19158, being reflected off the abundance of dust particles LBN 487.

Cocoon Nebula

Finally got a clear night to image (since I live in socal that means we had some clouds for 2 or 3 day). Temps were very nice for me, not so much for the camera. I need to finish that cooler box!

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.

Other details: guiding with PHD, captured with APT, stacked in Deep Sky Stacker and processed in PixInsight + Photoshop for final color adjustment.

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.
