Posted: Sat Nov 02, 2019 7:20 pm
M33, Triangulum Galaxy, captured under Bortle 6 skies. Celestron AVX + Vixen 81s + 0.8x reducer + Atik 314E. Teleskop LRGB filters. Polar scope with 2 + 4 star alignment and All Star Polar Align (ASPA). Unguided, focus with Bahtinov Mask. SharpCap + Astro Pixel Processor. L bin 1x1, RGB bin 2x2, 25 darks, 100 bias, 100 flats. Total Integration Time = 3h 15m.
Colour balance achieved at point of capture by varying RGB exposures. Many thanks to Brian (@oopfan) for his work at https://u235.herokuapp.com/ especially the LRGB Calculator https://u235.herokuapp.com/#color-balance-instructions and description of G2V stars and the use of AstroImageJ.
This object could do with more data and/or darker skies but for me M33 is now becoming 'meridian challenged'
