Scope:
FSQ-106N at f/5; Location: DAA Observatory, Shelter
Valley, CA; Dates: 26, 27 September, 1, 2 October, 2024; Camera: ASI2600MM (Astronomik
type 2c Ha, OIII and LRGB filters) Exposure:
Exposure: Lum - 90 x 3 min (gain-101
1x1), Ha - 132 x 6 min (gain-180 1x1), OIII - 132 x 6 min (gain-180 1x1), RGB - 36 x 2 min (gain-101 1x1) each RGB exposures. Processing: Data
Collection - N.I.N.A. Sequencer (as FITs). Sub-frame calibration -
Pixinsight (WBPP). Sub-frame registration and integration (Average combine
- Linear clipping) - PixInsight (WBPP). 2x Drizzle of Lum and
Emission Line stacks - PixInsight (WBPP). Noise reduction - NoiseXTerminator - PixInsight.
Non-linear stretching, normalization and gradient removal - PixInsight.
Photometric RGB calibration (SPCC) - PixInsight. Deconvolution of Lum, Emission
Line, and
RGB combine -
BlurXTerminator. Generation of starless nebulosity Lum, Emission line and RGB images for later processing - Star XTerminator. Curves, Levels, RGB
combine - PixInsight. Lum starless and Emission Line starless combine - PixInsight. LRGB
stars screened to starless Lum + Emission Line - Pixinsight. Final finishing, crop,
and resample -
Affinity Photo. Annotation - PixInsight, Aladin (Simbad),
and Affinity Photo. This image is an LRGB / HOO starless composition -
with RGB stars added. Image processed at 12496x8352 resolution. Final Image size is approximately
6207x4150. North is up in this image. The
above image is a modest crop of the full size image. This image shows the
brighter section and knots of this faint Supernova Remnant as well as some
of its fainter structure to the left in this image. Emission line structure in
Ha and OIII are shown as well as broad band structures and stars. The
mouse-over in the above image shows the difference between broad band only and
the emission line structures. The lower image mouse-over shows the difference
between the broad band and OIII structures. SNR G126.2+01.6 is faint -
making age and distance estimates less certain. But studies and analysis put
distance estimates between 11,700 to 18,200 light years and age between
210,000 to 270,000 years. There are several dark nebulae in this image
revealed by the broad band structures (Dobashi 3769, 3770, 3775, 3776, 3777 and
TGU H826, H834, H838 P7, H841). These objects and some of the brighter stars are identified in the annotated image. Horizontal Full FOV is approximately 2.52 degrees; above crop is 2.05 degrees. Full size image scale is about 1.46 arcsec/pix. Image center is approximately - Equatorial 2000: RA: 01h 19m 53s Dec: +64°27'04" OIII AND BROADBAND DATA VIEW MOUSEOVER IMAGE FOR BROAD BAND ONLY VIEW
