Hi everyone, Yesterday over on Cloudy Nights I posted a question regarding an image I've been putting together of the Soul Nebula. There was a rather large red-ish blur in the picture after I got through with processing it. The fine folks over there believe it's stray light getting into the camera f...

Here's what I ended up with after removing the Darks and following your general approach to processing the image:

What do you think?

Hey thanks! I'll give your suggestion a try and attempt to duplicate your method on that new stack. By the way, do you think there is more detail to be gathered here or would I be wasting my time with more subs?

Hi everyone! I'm back with another 2 hours of data on M33. I was hoping someone could take a crack at it as before? I feel like I'm getting close. This image includes not only another 2 hours of data, but I was able to drizzle the image with BackyardEOS, so I'm hoping that reduces the noise characte...

Thank you! I will certainly gather more photons is it were. I feel like I probably need about 4 hours work to get something decent out of it, so maybe another night or two of imaging. Appreciate the help!

Hi everyone, I've had the opportunity to come back with more data and try again at M33. I was hoping I could get some help processing this stack, as it's still a challenge. This stack includes about 1 hour of 3 min subs and ISO 400 and 1 hour of 3 minute subs at ISO 800. As you can see, I'm trying t...

Hi, Can you try just stacking the 3 minute subs? It may be the 1 minute subs are degrading the image. Can you also post one of the 3 minute subs as well? I'd like to see what has been captured. Thanks, Guy Sure, I would be happy to. Here is a stack of just the 3 minute subs: https://dl.dropboxuserc...

Hi everyone, I've managed to get a few more hours in on M33 and have taken a look at the results. Unfortunately my data is still pretty grainy and I'm wondering if I can't get some help with it. Here is a link to the stacked image: https://dl.dropboxusercontent.com/u/29126891/M33_20160927_20160923_s...

Bear in mind I don't know what scope, camera or mount you are using, but when I imaged it this time last year, I used 180 second subs at ISO1600. This was with the Astronomik CLS-CCD clip filter on a Canon 700d attached to my 8" Skywatcher. These produced a histogram that was barely 25%. A 300 seco...

M33 is quite a spread-out target and quite faint as a result. 60 secs at ISO 400 is going to be a challenge to get the signal out of the noise. Can you get to a less light polluted site for imaging, or if not and your light pollution is mainly caused by Sodium street lamps, consider a light polluti...
