M42 - Correcting "Fisheye" effect

Hello, I haven't set up a dropbox yet so I had to convert this to .jpg for posting. Since I've been stuck with cloudy skies every night since, well, June, I've taken the opportunity to learn my tools so I can be better prepared when the weather clears up out here. This means visiting old images from...

Easier masking process for faint background stars

I'd love to see some modification to the auto-mask process for handling faint background stars. I've seen the tips in the documentation which are helpful. The idea would be if there was some way to "sample" an existing background star that would sort of be a guide for the automatic process to better...

Re: Raw Images - Debayering/Stacking - Best practice?

Hi Carles, Stacking is actually the one process that always goes smooth as silk. Debayering has been kind of hit-or-miss unless it's done through the actual Orion Camera Studio software, which is also what I use for subtracting subs. What I'll do is calibrate all my images in one shot, save copies o...

Re: Using Heal to process stars and background independently

Now this could be very useful. Processing background stars independently of the main image would be very helpful for bringing out more of the really faint background stars in a shot. :thumbsup:

Re: NGC 7293 Helix Nebula OSC Narrowband Bi Color

You're most welcome. You definitely deserve the praise for the quality of this shot. It also goes to show that I received some pretty bad advice early on in my adventures in astrophotography. I need more light frames (I never did more than 20). That will probably help a great deal. Like the say, it'...

Raw Images - Debayering/Stacking - Best practice?

Hello, Though my images are shot with an OSC (One Shot Color), I never shoot them color-processed ahead of time. The initial image capture is in whatever Orion's weird variant of the FITS format happens to be. My question is this. Should I debayer the light/dark/flat/bias frames prior to doing the d...

Re: NGC 7293 Helix Nebula OSC Narrowband Bi Color

The word I would use to describe this is "overwhelming". I'm mesmerized by the sharp detail in the center of what is not a particularly large object. You said that you used an 8" reflector (kind of like mine) for capturing this object. One of the things I've been struggling with when it comes to my ...

Re: Messier 83 - Southern Pinwheel - Still learning but getting there

You may find this amusing. I decided the best way to use Compose is to just "get used to it". So on all my image processing I'm opening up the data as the linear with bayer option. Takes some serious getting used to, but it makes handling color adjustment much easier in the long run.

Re: Getting good data - Looking for guidance on exposure times

Hey, thank you for the information on this. I imagine it's a pretty broad subject. I got going on this when I saw that I think the guy behind the Fitswork application did a shot of M42 using 1800 1 second frames and it looked incredible. The advise I was given is, for your light frames, a minimum of...

Getting good data - Looking for guidance on exposure times

Hello, I'm going to do my best with this as I'm still learning all the correct syntax and terminology. If this question is stupid, I'll take my Stupid Cookies with milk this time :) When it comes to exposure times for images and building an image stack, assuming a camera shooting in prime focus, and...
