  • M15

    Object: M15 Date: August 27, 2007 Location: "My-Spot" Observatory, West Bloomfield, Michigan (4.2 ZLM, ~3.0 due to full moon) Exposure(s): 72 x 45 Seconds at ISO800 Camera: Hap Griffin Modified Canon Rebel XT (350D) Equipment: 10" f/10 Meade LX6 OTA with UHTC optics and Lumicon GEG @ f/7.5, Losmandy G-11 Guiding: ST-4 (A3's) on ETX90 OTA Software & Processing: RAW image files were dark frame & background subtracted and converted to Tif files using my RawHide RAW file converter. The Tifs were then aligned and stacked using Registar 1.0.7 and then processed using Picture Window Pro. The full moon was only 27° south of M15, as a result, subframe exposure time was greatly limited due to skyglow.

  • M52

    Object(s): M52 Date: Sept 1, 2002 Location: My-Spot Observatory Exposure: 3x 15 Min Film: Kodak Royal Gold 400 Equipement: 10" f/10 Meade LX6 OTA (w/UHTC) w/Lumicon GEG with focal reducer at f/7.5 position Guide Scope: ST-4 autoguider (A0 - A2's) Hardware & Software: HP S20xi film scanner (2400dpi). The images were color corrected, processed, and cropped using Picture Window and then digitally stacked using Registar. Info: M52. I am fairly sure that the RG400 film used for this image was the "old" (read: good) stuff. In any case, M52 is a boring little open cluster. At least the focus and the tracking a good. The mouse over shows you the full scan resolution.
