Rodd Posted November 4, 2018 Share Posted November 4, 2018 This is the first modicum of success I have had with this tricky target. I see now that my trouble was not having near enough data. Even this image, which consists of 204 1min lum subs taken with FSQ 106 with .6x reducer and ASI 1600 has nowhere near enough data...but I can see the potential. This is 204 subs which were not inspected or picked through. I integrated all of them just to get an idea of where I stand. Some in the beginning should probably be nixed, as they were taken when Orion was still low in the sky. But--at least I know its possible, which was not the case at all prior to this morning. Still a bit grainy and blotchy--though its getting better. Doubling the data should help. Then with the addition of the RGB and Ha stacks, I think it will work.

Rodd Posted November 5, 2018 Author Share Posted November 5, 2018 Here is a mono image consisting of Ha for background and loop, and Lum for M78. Its hard to isolate M78. I would have liked to transfer the dark horns. Link to comment Share on other sites More sharing options...

A devil of a target. I dare say I'm coming to the end of my three year sulk following my last attempt so I might - only might - consider approaching this one again this winter. But I scent victory for you, Rodd, in this approach! Attaboy... Olly Link to comment Share on other sites More sharing options...

He would look like the world was coming to an end, and I would ask what the problem was. His day was doomed because he had gotten a B+ on a quiz! ?

gorann Posted November 6, 2018 Share Posted November 6, 2018 Looks very promising to me Rodd. If you are interested you can see my attempt at it here with unfortunately only 5 hours of data using my Canon DSLRs and a Canon 300 f/4 telephoto lens supplied with additional data from my ES 5" budget apo. Should hit it with my Esprits and ASI cameras, but only clouds forecasted here for the next week. Not an easy target and as you can see I got to version K before letting it be: https://www.astrobin.com/319196/K/ Link to comment Share on other sites More sharing options...

It always amazes me how a target changes with the camera angle--I guess that's why we can shoot these things over and over and not get tired of it. Just rotate the camera a bit a Voila, there is a new image! It almost looks like there is a red lane extending from the loop on which M78 sits.

Rodd Yes, I have been rotating my recent Sh2-115&116 image over and over again. Looks very different, and with differnt qualities, and I cannot make up my mind.....

That's why this hobby is so great--we can shoot and reshoot the targets over and over again and always have an interesting, different image to admire. I tend not to rotate because I think you need all new flats if the camera angle changes. Olly and others do not feel the same way (if I remember correctly). I would love to rotate the camera at different angles for different targets. But, I will say, even with a CAA, I can NEVER find the exact same angle twice. If I rotate the camera and then try to revisit a target and rotate the camera to try and match the angle--never happens. It is very strange. I will align a star perfectly, but other stars will be off by 1/4 inch on the screen. But the funny thing is--stars in a different location in the FOV will be off in different directions, so if I rotate the camera one way to align some stars, others will be off. I do not understand it. Because of this (and needing new flats--maybe), I am loathed to change the camera angle. Rodd Link to comment Share on other sites More sharing options...

You of course got a point that rotating the camera while finding the best framing is also an interesting/frustrating exercise that easily can use up valuable imaging time....

tomato Posted November 8, 2018 Share Posted November 8, 2018 There is a BAA report that McNeil’s Nebula, a variable Nebula in the vicinity of M78 has disappeared. If I have my location correct, your image would appear to confirm this. A cosmic event captured, congratulations!? Link to comment Share on other sites More sharing options...

So it does appear to be gone. Too bad I was not the first one to image this. Still interesting though. maybe it will reappear during my RGB subs--or just the red subs and then people will say that it turned mono!

Rodd Posted November 8, 2018 Author Share Posted November 8, 2018 I now see in Goran's image the nebula IS there. So....I am convinced.
