A 10 hour image of the Needle Galaxy (NGC4565) shot over 3 nights (13., 16. and 17. April 2020). I struggle with obtaining good flats, but hope to improove this next season. Also the sharpness could be better, poor sharpness probably due to reduced seeing one of the nights. May be I should do a harder selection of the images to process?
