Far too kind Thank you. The data would have allowed for a more aggressive processing, but I guess, that's just not my kind. Most times

Best regards, Dietmar.

Thank you Martin! :) using a DSLR with some obvious limitations Absolutely true, it cannot compete with dedicated astro cams. No way. But I think it works much better than older EOS models, at least as far as I can see. A beautifully designed and engineered piece of Astro software !! Sure, agreed! S...

Hi all, I guess an astrophotographer who hasn’t photographed the Pleiades is not a real astrophotographer, no? (Of course, except for our friends living under southern skies.) After weeks of cloudy nights there has been one single clear night and so I gave it a try. https://cdn.astrobin.com/thumbs/w...

That really looks great, Martin! :) So much detail at only 4 hours of integration time. Mono and high quality filters really seem to be the way to go in case of such light polluted skies. Nothing to improve as far as I can see. Unless you want to consider to cut the branch of the council tree ... ;-...

Hi Stefan, thanks for your reply :) Did you have to fiddle a lot manually? And did you also layer in the color of the brighter stars with spikes? Oh yes, that's maybe worth mentioning. No, no extensive fiddling. First, I'm a quite lazy guy, at least regarding boring work and second, I've never been ...

Thank you Martin :) Yes, in almost all cases the results of OptiDev/AutoDev are of superior quality compared to FilmDev. But there are some rare cases when FimDev does a better job for me. I don't know why, but I guess, it's the very poor quality / weak signal of my dataset in this case. So yes, it ...

Hi all, At the beginning of November there have been a few clear nights here at my location, which I used to gather some data of the Cave Nebula. My intention was to acquire broadband- and NB data in order to combine them using the NB Accent Module. But the quality of the broadband data was unusable...

Hi Stefan & all, I then adjusted the blackpoint (in pretty coarse manner). [...] This means that a simple adjustment of the blackpoint distorts the signal ratios across the image massively. I never considered an adjustment of blackpoint non documentary. Is it? Good catch. I think, basically you’re r...

Second - how is preservation of relative emission strengths impacted by using substantially increased exposure times for Oiii vs Ha? This is obviously not an issue for OSC-duoband, but it's pretty common practice in mono imaging. Apart from different integration times it gets even more complicated ...

Hi Andrew, I would guess, that this is caused by atmospheric refraction: https://en.wikipedia.org/wiki/Atmospheric_refraction This star seems to be nicely round, so this is most probably no problem which is caused by stacking. Another possibility is chromatic aberration of your optics (if glass / le...
