Heart Nebula

Image obtained 12-02-2015 through RVO's Megrez 80mm refractor with Orion field-flattener lens, using a Baader-modified Canon XSi DSLR and BackyardEOS image-acquisition software – 22 (of 24 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 320 minutes (~110 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.

 


 

Note -- click this text to be linked to an excellent and entertaining tutorial discussing this object and the methodology of finding it without the use of digital setting circles or go-to auto-aiming technologies. Excellent!
