Re: M45 can I minimize diffraction spikes

Aha! The multi-date acquisition may have something to do with it. If the orientation of the camera vs object changes, then the diffraction pattern will change as well. This can be a good thing too, as some stacking rejection algorithms will be able to reject the spikes if they keep changing per fra...

Re: M45 can I minimize diffraction spikes

Thanks Ivo, as you may recall, I don't think as well as I used to. I'll bet that's the issue, but if it were taken by an FSQ 106, there is a camera rotator which should have cancelled that out if it were used correctly. Perhaps that is the root cause of the uneven and multi angled spikes. I can live...

Re: M45 can I minimize diffraction spikes

Thanks for your reply Ivo, Thank you Troy. It's a lovely image. Diffraction spikes on these bright stars are usually par for the course in M45 renditions. You really kept the stellar profiles under control well. What does throw me off a little though, is that the spikes are all oriented differently....

Re: M45 can I minimize diffraction spikes

Hi Troy, Diffraction spikes are usually considred a fact of life, however you can try to heal them out. Would you be able to post a screenshot/example of the issue you are seeing? Clear skies! Hi Ivo, I hope all is well with you. I'd love to post a shot, but the link I left in my message is the onl...

M45 can I minimize diffraction spikes

I have some clean M45 data from what I thought was an FSQ-106, but when I processed it, I have what I believe are diffraction spikes. Perhaps it isn't from an FSQ, or perhaps I should not have used AutoDev, should I try and use Dev instead? I'm happy with the image color, but I'd appreciate any idea...

Re: Welcome!

Hello Ivo, It's been awhile, and our weather was so terrible this past 9 months that joined Deep Sky West to get some data to play with. Now it might be in the manual, but remember I'm dumber these days since my strokes. I'm struggling to figure out how to get bias frames, flats, darks, etc. into St...

Well, I managed to get out for the first time in months. I imaged the Orion Nebula, and decided to have some fun with it. FSQ-106n & Mallincam DS2.3Plus It is wild what different choices in processing bring out. Not Sky & Telescope material, but it could hang in an Art Gallery...well, maybe :lol: Or...

Re: Difficulty in posting private message

Oh by the way, that is my personal website. It is a virtual I lease for $130 per year, and only I have upload capability. I got to thinking, it's Linux based, and the Vendor has it locked down pretty tight, only I can enable ports which are uncommon. I do understand your hesitation, but I began to t...

Thank you happy-kat! I have posted a link on my website at http://tgalebachmo.net/Horse_stacked.fit It is 50 frames stacked with no white balancing hope you can help me decide which is the proper way to load the file. It is tough remembering things for me these days, but I'm not going to give in wit...
