Astrobdlbug Posted March 18, 2021 Share Posted March 18, 2021 Here we are again - after my Tadpole Nebula (declared last image of season 🙄) , here is the next last nebula image of the season..... This week the skies cleared for a few hours on Tuesday and Wednesday, the transparency was not that great, especially on Wednesday and as the winter nebula fade westwards into the atmospheric haze and light pollution from the many distribution sheds in Northampton imaging time is quite limited - basically 8pm - 11pm give or take 30mins. That being said, these new Antlia 3nm filters do seem to be quite resilliant to the LP and surprisingly the atmospheric haze does not seem to have resulted in any fuzzy stars . I managed to pull down 2 hrs Ha and 1hr each of Oiii and Sii, total 4 hrs Integration over two eveings. Processed with APP / Pixinsight / Photoshop CC NGC 2174 is approx 6,500 light year distant I have posted the full frame , slight edge crop to remove stacking artifacts and then a closer crop as the image seems to support the crop. I also rotated the frame 90deg to make the monkey head more apparent in this nebula (sometime I see it clearly and then it dissapears) Bryan Image Information Dates: March 16, 17, 2021 Imaging telescopes or lenses: Astro Tech AT106 EDT Imaging cameras: ZWO ASI1600MM Pro-Cool Mounts: Skywatcher AZ- EQ6-GT Guiding telescopes or lenses: Astro Tech AT106 EDT Guiding cameras: Starlight Xpress Loadestar 2 Focal reducers: Riccardi Reducer/Flattener 0,75x Software: Aries Productions AstroPixelProcessor · PS CC · EKOS KSTARS INDI RASPBERRY Rpi4, EKOS, INDI, AstroBerry · Pleiades Astrophoto PixInsight 1.8.8-4 Ripley (x64) Accessory: Celestron OAG Frames: Antlia Ha 3nm Pro 1.25": 24x300" (gain: 200.00) -20C bin 1x1 Antlia OIII 3nm Pro 1.25": 12x300" (gain: 200.00) -20C bin 1x1 Antlia SII 3nm Pro 1.25": 12x300" (gain: 200.00) -20C bin 1x1 7 Quote Link to comment Share on other sites More sharing options...
