GSO 305 mm - Canon T3 - ISO 800 - 4 x 5 x 4 min (80 min) - OAG - Skyglow filter - Coma Corrector
I am not very glad with this work. My set distort the image at periphery and I can't assemble the mosaic with perfection. Some areas of final result have a strong error of star position.
Other issue is a black frame border for each photo. Clean them is very hard.
In short words: my set isn't good for mosaic !
