M3 and NGC5263

[dunc]

Globular clusters are good targets when there is a bit of Moon in the other half of the sky. I'm particularly happy getting colour and detail in NGC5263 at the bottom and there are some other galactic blobs around as well. The sky was excellent and I am lucky to live in a 21.47 dark zone (when the street lights go out at 23:00).

41 of 50 x 250s, Gain 121 (unity +1 for luck), Offset 4, Temperature -15c. Stacked using PI BatchPreprocessingFD (Micheal Covington version) so Flat Darks are used instead of Bias frames. The stacked image was then saved as 32 bit uncompressed TIF and loaded into StarTools for stretching, gradient removal, colour correction, deconvolution, denoising and saving as JPG (seems to have a very good algorithm for this).

Image date, time and location:   2019-04-12 23:00-01:00CET Manche, France
Telescope aperture and focal ratio:   TS1506UNC f4, TS Komakorr
Camera and filters used:   ZWO ASI294MC Pro, Baader Neodymnium 1.25" filter
Processing applied:   Pixinsight, StarTools, Irfanview
