Description

An other M31.

ISO 800, 51x40".

With a flattener/reducer this time.

But I haven't found the good distance with backfocus for my refractor, so the picture is soft, and there is still coma in the edges...

According to the information I've read, i need a 5 mm extension tube.

I'll try next time. For now, it's raining in France
