Review OOTM from 2023 or 2022.

March 2024 Objective: Pick an object in the constellation Leo.
  • object: Leo Triplet
  • imaged by: Bennie Palmer
  • image capture/processing details: This captures the “Leo Triplet” (M65, M66, NGC3628). Presented is an 87000s (~24 h) integration of an L RGB capture from an Astrotech 130@f7 fl910mm, 0.80 FR scope with ASI2600mm camera using Optolong filters, ASIAIR, and was off-axis guided with an ASI290 mono camera. It was cheerfully processed using magical technology contained in StarTools, Siril, Gimp.
  • location: Ellicott City, MD
  • date: March 2024

Jan/Feb 2024 OOTM was the Jellyfish Nebula (IC 443)

TIE: Bennie Palmer and Lee Amos
  • object: Jellyfish Nebula (IC 443), a galactic supernova remnant in the constellation Gemini.
  • imaged by: Bennie Palmer
  • image capture/processing details: captured for 19.5 hr in narrowband filters and is presented as an SOH mapping onto the RGB pallet. Using an Astrotech 130 refractor setup as f7 with a focal length of 980mm with a 0.80 focal reducer. An ASI2600mm mono camera was used and controlled by an ASIAIR plus on an iOptron CEM70 equatorial mount guided by an ASI174 off axis. Processed in Siril on an iMac with lots of fun discovering the filaments, structure and colors of this enjoyable target.
