I need to really work on the masks so I don't loose the red in M42. Still a work in progress but I wanted to share. Canon XS unmodded Tokina 70-210 SD, Nikon mount with EOS adapter (20 dollar lens!) @ 210mm F6 Piggybacked on LX3 60 1:00 subs and 60 darks Stacked in Deep Sky Stacker and Processed in StarTools Post Extras:       TimN professor emeritus Reged: 04/20/08 Loc: Ontario, Canada Re: Orion Region 210mm Lens Redux [Re: shawnhar]       #5519999 - 11/14/12 07:06 PM Edit   Reply   Quote Quick Reply   Nice wide field Shawn. We usually see M42 and B33 imaged separately. This gives a nice overall perspective.

I think you have a nice image going...maybe collect more data?

I cannot wait to try my first one out in the near future. Very nice image and with more data I'm willing to bet that $20 lens will be a very good investment.

I have only tried to combine data from different nights once before, it didn't go very well. I do have about a dozen subs from my 1st attempt at this. I will ty to use that data combined with above and maybe I will learn something this time. No break in the weather for the rest of the week so I plan to milk this data for all it's worth anyway. I have a guide camera coming soon and plan to try for some 3 or 4 min subs on this. Terry, you are correct, I was happy B33 is plainly visible, although I had to cheat, that whole area was masked and red boosted/saturation to get it to show up. Tricky task to keep it looking semi-natural, 1st couple of times it stood out like a sore thumb!

Spent some extra time on masks and star color, pretty happy with the way this one came out, even entered it into the monthly contest!

I think this is my best astropic to date. As mentioned, I plan to go out tonight and get more data. The dozen extra subs combination seemed to work pretty well. (Although the above pic did not have those subs) I hope to add another hour to this and see what I can get. was REALLY stoked to see a hint of the faint dusty structure in this area!

I think it is a big improvement over the original. You can see the Horsehead more distinctly as the ionized gas behind it is more evident. Overall the colors look nicer and brighter. Looks good to me.

I can see that it is better, but with 3 hours of integration, really thought the dusty bits would be more apparent. I can tell it's there if I convert the image to black and white, but it's hard to distinguish from the background gradients.

Had some stacking issues with the lower left side, I think it's from poor alignment causing field rotation. See larger size here: http://www.astrobin.com/full/24783/D/?

You would certainly see more of the nebula if you did. I understand that you may not want to if you still want to do terrestrial photography, but you could use custom white balance to compensate on the "earthly" pix.

Zooms lenses generally don't do as well as primes. And shooting at f/6 (vs. f/2.8 with my Canon 200L) extends your exposure time significantly.

I never realized the HH was this big. Thanks for the pic.

Phil, I hear you on the primes, but they are proud of those things! I have an old Nikon 200mm F4, that was my 1st lens purchase, but it has some fungus or something behind the glass, right in the middle, causes a very soft image ,that's why I ended up with the Tokina, supposed to have super low dispersion glass, I just wanted a 200 or 300mm lens so I could start doing some widefield on a budget. I keep looking on KEH for a bargain grade fast lens, but you really can't match those L lenses. I plan to take this exact shot again with 4:00 subs, at 1:00 with my skyglow, the data is barley above the background noise.
