M31 spiral galaxy in Andromeda with adjacent irregular galaxies M32 and M110 / NGC205
M31 Andromeda Galaxy

 

Image obtained 11-03-2015 through RVO's Megrez 80mm refractor with Orion field-flattener lens, using a Baader-modified Canon XSi DSLR and BackyardEOS image-acquisition software – 26 (of 28 obtained) carefully selected and stacked 300-second luminance frames combined with multiple dark, flat and bias calibration frames shot at ISO 1600 and totaling more than 360 minutes (130 minutes effective luminance) were used to create this image; optics driven by the Losmandy G-11 mount equipped with Ovision's precision RA worm gear, guided with an Orion SSG3 Monochrome CCD camera using Maxim DL Pro and post-processed with DeepSkyStacker and Photoshop CS3.


Intricately spiraled M31 is the main object, shouldered by M32 (below and seemingly within) and M110 / NGC205 (above) the larger spiral galaxy, most distant of easily seen nighttime objects.
