    AI Gigapixel testing

    Answer to that is: No. It works relatively well with heavily undersampled data: Astro test 1 But it doesn't bring any additional details in well sampled data. In fact it creates extra stars and details out of noise: Astro test 2

    AI Gigapixel testing

    Topaz labs has released new AI based image resolution increase and enhance software and they claim it to be "stellar": https://topazlabs.com/ai-gigapixel/ I have been briefly testing it and thought to post my findings here as well. Here is the first test, original image is on the right and on the left is a 1/4 resolution reduced one to find out how AI can improve it and perhaps return it to back. Middle is the AI 400% resolution increase result. Files are large so I only post links: Test 1 Second test is a native resolution increase and then viewed in same size than original: Test 2 It seems that AI work better, at least to my eye, when resolution is first increased and then reduced to back normal - use it as a sharpener of some sort: Test 3

    Too much data that put my computer on its knees

    Or just start binning 2x2 during the capture because I use that same camera in OAG winter time. Either way can’t keep processing data resulting 10.000 x 10.000 pixel end images with pointless over sampling.

    Too much data that put my computer on its knees

    I tend to think that the benefit of 14bit vs 12bit is not that big. In fact I have failed to notice any difference, but I can only speak on my behalf and it doesn’t mean the benefit isn’t there. For me it makes sense trying to capture best seeing with less bit depth and more disk space. I’ve also understood it doesn’t increase dynamic range to use larger ”colour” space - it only makes shade transformation smoother but we stretch the data like crazy persons in the end anyway

    Too much data that put my computer on its knees

    I'm using 500GB SSD, but it still feels like it fills in a mere moment with ASI178. 3000 frame SER file takes 18GB captured 12bit and 14bit takes just a insane amount of disk space. 20 stacks 3000 frames 3000x2000 pixel each just makes my computer crawl. It helps a bit downsizing files to 1500x1000 pixels to reduce over sampling, but my flats tend sometimes get out of sync then. Hardware binning could help this and I did some experimenting last season even though didn't draw any final conclusions on quality. I'm also dreaming of better computer, but it sits 99% of time idle so it feels a bit unnecessary to put 1500€ into more cores. Or does it...

    How much data do you normally take Dave? I’m thinking to switch from 14bit to 12bit capture and bin as well.
  7. For two days I most likely need to scale it down before AS3 processing, or upgrade my gear. Still working with my trusted i7-870. Anyway, this was captured 19th of April.
  8. Almost new, only couple of times used - perfect condition! For sale to clear room for new gear More info: Vixen SG 2.1×42 Binoculars Review Vixen SG2 Widefield binoculars SOLD

    Some details in sun 14th April

    Year is still young and it’s called lucky imaging for a reason Seeing lottery favored me this time
  10. For sale Astronomik 12nm 2" HA Filter. Couple of years in casual use, stored in warm and dry. In very good condition, I can post images if needed. Teleskop Express Astronomik 12nm HA filter 200€ + post fee This was shot with it near airport:

    Some details in sun 14th April

    Thanks, it happened to be a moment of top seeing during the capture. The surface part wasn’t that good.

    Some details in sun 14th April

    Sun is pretty dull these days, but got nice details yesterday. Plan was to make comparison today, but clouds rolled in that's about it then. Spot 2704

    My honest, and somewhat painful opinion is, even though I don't dare to think about it, that I made practically as good images with my TS65Q and Quark than now with slightly more expensive 106ED, 110mm ERF and Quark. Here's something taken today: My directions are messed though and need to fix that in next images..
