  1. Well I never really had any previous problems with focusing using a Bahtoniv mask. But being all new to that CCDinspect software, I did get this result from using all 23 images combined.
  2. Focused on the blue, what do you mean by that? I used a Bahtinov mask, and focused on the yellow star Pollux, all the spikes were perfectly alligned.
  3. I figured out how to use the CCDinspector, to inspect my subs, not sure if I used it correctly, but I'll upload the results I found.
  4. I was in perfect focus before I started, but maybe focus shifted. I imaged another target for 40 mins before this one. So slewing, cables hitting the focus knobs during slewing, slight temperature change might have changed iy.
  5. If it's only a focus problem, I'm relieved, but wouldn't focus affect ALL stars, including those in the middle?
  6. I couldn't find the trial version, I downloaded it, installed it. And it let me use it once. Then it couldn't open cause it said I need to buy a license..
  7. I heard that this telescope, reducer fitted with a DSLR dosen't need any spacing, as it fits directly, even FLO said this to me. Again I used a Nikon D5300 with this exact setup with no issues. Actually I'm on it right now to see.
  8. But coma with a reducer/field flattener dosen't make sense? All my subs are like this, stars are fine in a "circle" around the middle, but everything outside this "circle" and the stars are looking like this. When I did some flats awhile ago, which are now deleted, as I deemed them unusable, they clearly showed a circle in the middle of the image, which makes sense with the stars in the light subs.
  9. Here's a single stretched, non-calibrated sub. But guiding was between 0.50-0.80" RMS
  10. But still wouldn't guiding affect ALL stars, and not just those around the corners?
  11. I've been noticing some weird looking stars, all around the edges and corners of my last two images. I tried to figure out what it could be, but spacing shouldn't be the issue with this, as I see tons of people using pretty much same setup, just different DSLR cam. Also I tried the same setup with a Nikon D5300 with no issues at all. My setup is: SW Evostar 80ED 0.85x SW Reducer/Field Flattener First Light Optics Nosepiece Nikon D5600a SW Heq5 Pro mount Please zoom in on the image to really see the star shapes.
  12. Hi guys So I've imaged IC 1805 over 3 seperate nights, getting a total of 6 hours of integration time (60x360 sec subs), using my STC Astro Duo-Narrowband Filter. I've tried to bring out the blue from the OIII, using different methods, and techniques, and in PS and PI, but nothing really brings out the blue in my image. I was aiming at a HOO image kinda like this: https://www.astrobin.com/209354/C/?nc= Even tried simulating the Hubble-Palette, which normal easily bring out the blue, and then some green, but even that didn't work. I did get the famous golden color though, but that's it. So hopefully someone here can help me? Gear used: SW Evostar 80ED SW Heq5 Pro Rowan Belt modded mount Nikon D5600a STC Astro Duo-Narrowband Filter Bortle 4 backyard Stacked in APP, processed in Pixinsight & Photoshop. I've attached the image from my best try in this topic:
  13. Hi all. First of all, can you extract HA from OIII in DSS, as you can do in APP and PI?, my license ran out on both APP and PI, so I have to stack with DSS right now, as I can't afford a renewal at the moment. Also if yes, I'm curious on how you color map them in PS, let's say R=100% Ha, G=100% OIII B=85% OIII and 15% Ha? I have Noel Carboni's action tool, but not sure how to properly do that. Probably should say I used a Nikon D5600a, and a STC Astro Duo-Narrowband filter. Best regards, Mats
