Capture: ArtemisCapture
Autoguiding: wxAstroCapture (FS60c)
Calibration: ImageTOOLSca
Stacking: ImageTOOLSca
LRGB processing: IRIS + Photoshop CS2

This was an excercise image after very long pause in LRGB imaging. There are many imperfections due to using old flats and darks. The FS60c was mounted "piggyback-style" and guiding with Vesta SC3 colour.

The guiding with wxAstroCapture was using File Interface towards MTSca Pro. It will be interesting to see how wxAstroCapture native telescope control might work when that is completed.

Due to heavy dew problems, this image appears somewhat fuzzy.

NGC891 shot using my C8 and Vesta 690 SC3 B/W camera, with 0.6x focal reducer.

The image is a mosaic of 2 series 80x25sec and 90x25 sec. Increasing fog and clouds made it difficult, and leaves it open for another try under better conditions.
