Photo description / processing

I continue testing the wonderful astrograph Askar SQA 85. Indeed, an almost perfectly flat field across the entire frame, stars at the edges are not stretched, which of course no Newtonian can achieve. Thanks to Oleg Chekalin for the consultation before the purchase. I added more material and improved the processing.
