Adam Y Posted February 12 Share Posted February 12 This one fought me all the way, but I'm reasonably pleased. I naively thought I could just pop my DSLR with a t-ring and nosepiece in the diagonal and be able to get something. Ran out of focus all the way in, and so I learned about back-focus. Got myself the proper T-adapter along with the .63 SCT reducer/corrector and now I was able to get focus. Solar cap filter > Celestron 8SE > reducer/corrector > adapters > camera. Camera is just a Nikon D90 with no filters or mods. ISO 400 with an exposure time of 1/50th of a second got me a pretty nice histogram somewhere around 80-90% in live view. LOTS of spots on dear old Sun!! Took about 60 frames with 20 darks and 25 flats. Used PIPP to calibrate and sort the RAW pics according to quality and convert to .tif. AS3 to stack, pretty much just the basic option here, keeping the best 95% of a really good set of frames. Registax 6 for wavelets then over to GIMP for some mild stretching exercises. I used Colour > Levels to align the RGB channels, then boosted up the red just a touch until it was pleasing enough to my eye without being garish. That part is subjective, I know. Now I really want to get a Lunt or Coronado! But for now I'll get back on track with DSO stuff as soon as it is warm enough that I feel like standing around outside all night. Might try the moon while I'm at it! Thanks for looking, this is fun. 1 Quote Link to comment Share on other sites More sharing options...
