CLICK ON IMAGE FOR FULL SIZE VIEW (3200x2400) Scope: Explore Scientific MN152 Maksutov Newtonian at f/4.8, Location: DAA Observatory, Shelter Valley, CA, 3 March 2020, Camera: ST8300M (Baader LRGB filters) Exposure:
Exposure: 16 x 10 min (1x1 bin) exposure with UV/IR block filter, 10 x
4.5 min (2x2 bin) each RGB
exposures.
Processing: Data
Collection - Sequence Generator Pro (as FITs). Sub-frame calibration
- Pixinsight. Sub-frame registration and integration (Average combine - Winsorized Sigma
Clipping) - PixInsight. Non-linear stretching, normalization and
gradient removal - PixInsight. Curves, Levels, RGB combine, Luminance
layering - PixInsight. Final finishing - Affinity Photo. RGB calibration
- PixInsight. Annotation - PixInsight, Aladin (Simbad and NED), and Affinity
Photo. This
is a RGB image with luminance layering. The Luminance stretching
on stars was light to minimize star bloat; galaxies had a heavier stretch. The
heavier stretched galaxies were merged with the lightly stretched stars.. The resulting image was used as luminance for the image
consisting
of the RGB data. Images processed at 3352 x 2532 resolution. Final
Image size is approximately 3200x2400. North is up in this image. Image center is approximately - Equatorial 2000: RA: 10h 36m 35s Dec: -27°31'06"
