Description

782 60 secs unguided subs taken on the nights of the 11th and 12th of April. Orion 250 F 3.9 telescope, qhy183mm camera, Ioptron CEM60 EC mount. Aquisition and part of the process (star elongation correction and some little deconvution) with Astroart. Remaining process (mainly cosmetic) with PS.

Some gradient, that I have not been able to remove, is left on the image. This probably is due to high amp glow of the camera, that is left even if I have applied 90 darks.

Thanks for looking
