    M33 ATIK 428 OSC

  2. A tough deepsky object especially if you are using a small refractor like SW ed 80. Anyway it seems that this small semiapo telescope can do more things than we think it can. Hope you like it. Location : Mt Parnon & Athens-Keratea (Pegasus Observatory 2.5) Constellation : Pisces Telescope : Skywatcher ed80 f/7.5 CCD : Atik 428ex Temperature of ccd : -10 celcius Mount : Eq6 Guided with : Ts oag Focal Reducer/Flattener : No Image scale : 1.56 arcsec / pixel Field of view: 50.25 ''x 37.77 '' Filters : 2" Baader Filter Wheel : Starlight Express Focusing with Pegasus Astro Dual Motor Focus Controller Sub-exposures : Lum 42 x 600sec Red 38 x 300sec Green 20 x 300sec Blue 15 x 300sec Calibration frames : Bias,Flats,Darks Stacking with median combine Maxim DL Capture : Nebulosity 3,Maxim DL Process : Photoshop CS6 Tracking : Eqmod
  3. First light for my new Tec 140 and i'm very happy with the result. Hope you like it and thanks for watching. better image quality and more info here
  4. Two clear nights running to try out my new Samyang 135mm with the 428ex. This is 24x300s processed in PI: DBEx2, MaskedStretch, HDRM + LHE. I know this combination produces significant undersampling but that aside I am very pleased with the widefield capability now available with the 428ex. Thank you for looking. Adrian
  5. Sometimes the weather gods look on you kindly. A nice new Samyang 135mm turned up from that well known jungle supplier, I managed to assemble it to my Atik 428ex mono along with an Ha filter and got the spacing correct, and low and behold the skies stayed clear - all on the same day! I am sure there is room for improvement with the processing but this is IC1396 processed in PI; STF applied with HT, and a little HDRM + LHE to try to tease out some detail. Any help on improving the processing would be gratefully received - I really don't feel I get the best out of processing mono images. By the way this is 12x300s + 10x600s combined with HDR process in PI; flats, no darks and a master bias. Thank you for looking. Adrian
