  1. Just what I were looking for! Thank you very much
  2. Anyone know of an easy way to mark bad image files (FITS format)? I have some 100 fits files from my last session, and want a good way of quickly look through them and mark the bad ones with a prefix so that I don't have to run them through the SubframSelection in PixInsight. I have some FITS viewing applications, but none are easy to use for this purpose, they are all built to open one image at a time, close it, open the next etc. Thanks /Patrik
  3. Found this thread by accident, and sorry for kind of hi-jacking it, but I wanted to direct a big thank you to @Scooot I have been following the tutorials on Light Vortex, and they are excellent...but I was not aware of the above. Attaching a sample with and without bias calibrated darks. To the left is a stack of images calibrated with a bias calibrated master dark, to the right is a stack calibrated with a master dark without bias calibration. Thanks /Patrik
  4. The Astrodons are obviously better than my Baader filters, so lets hope for the best My Baader NB filters also claim to be parfocal, but are not on my f/5 scope...atleast not parfocal enough to produce pinpoint stars without a refocus. /Patrik
  5. Nice one! Love this target but have never come around to imaging it myself. Sorry to spoil the fun, but is there really such a thing as a parfocal imaging setup (using "normal" f-ratios)? I'm not an expert but would say no /Patrik
  6. Nice one, I also tried to image this a couple of years ago with an unmodded DSLR, but couldn't capture the details that you've got there. I think that a bit softer processing would benefit the image, with a more even sky background. You've got some nice data in there Thanks for sharing
  7. Wow, amazing image, I would frame that and hang it on the wall Love the framing and fov, so much going on in there /Patrik
  8. Thanks Martin, means alot! I think I was a bit lazy with the new autofocuser. I told it to focused when changing filters, but maybe I should tell SGP to focus every 5 frames or so to compensate for temperature changes, meridian flips and such?
  9. Hi! I originally posted a rough version of this in the beginners section and after getting some valuable tips on processing I decided to post it in this section as well This is my first post in this section, but I'm actually kind of happy with the result! It's not as crisp or detailed as many images in this section of the forum though. It's my first go at combining Ha, S2 and O3 into a color image, and I've been following the PixInsight tutorials on Light Vortex Astronomy. The image is a combination of 15 x 600s Ha, 16 x 600s O3 and 10 x 600s S2, totalling almost 7 hours of lights, combined with darks, flats and bias. Shot in Stockholm, Sweden with a SXVR-H18 and Baader narrowband filters. Any suggestions or possible improvements welcome. Thanks for looking /Patrik
  10. Ah, I think I misunderstood you, I just ran a 90% scnr on the original, but averaging them out like you did looks better. Will have another try tomorrow, starting from the beginning. I'm getting hooked by the processing now It's Bromma Airport, I'm glad I didn't get any airplane trails in any of my subs
  11. Wim: just wow! Thanks for the tip! The amount of skill on this site is amazing! Sorry for spamming, but gotta post the edit after SCNR Looking through the image progress in this post is kinda comic, lol
  12. Thanks alot for the peptalk Jason ? I gave it another try, with both stacking and processing in PI using various tutorials. Still lightyears away from your image, but at least I'm getting some better results! I have a lot of learning to do... I think the black specks came from clipping during integration as suggested Wim, playing with the values gave a better end result.
  13. Thats amazing Jason. So much detail and a nice black background with great contrast! Here's my quick Hubble attempt using PixelMath, which is nowhere near your image. During stacking I reused flat frames from a previous session (I know I know... ? ), which resulted in a quite nasty gradient that was hard to cope with, hence the massive cropping and halos around the brightest stars. I've tried the tutorials on LightVortex, but my attention span might be a bit short for narrowband image processing. I just want to stack the images in DSS and give it a quick 1 hour process and move on to the next target But looking at your image it sure is worth it. I image with a SXVR-H18. I think the tracking, focus and integration time is good enough to produce much better end results. /Patrik
  14. Tried a quick hubble edit, but I think I need alot more S2 and O3 data for it to work. Found it difficult to control the green in the background (probably due to lack of PixInsight skills )...Will give it another go tomorrow. CosmeticCorrection didn't do the trick for me, I still ended up with the black specks in the stacked Ha image I've tried all stacking methods in DSS and can't see any black specks in the single exposures, so I'm clueless. Will try to learn stacking with PI /Patrik
  15. Thanks for the input, I'll give Cosmetic Correction a go. I think the specks originate from the stacking though, since I didn't see them in the subs at a first glance, but might be mistaken You're right about the colors, Ha is mapped to red, O3 blue and S2 green. I've never tried the Hubble palette, but will give that a try as well!
