Description

Last night I tried an imaging session with M51 the Whirlpool Galaxy: around 4,4 hours with my SkyWatcher 200PDS and ASI533MC camera. At 3h in the morning something went wrong with the autofocus: ASIair says "AF succeeded", but the image was completely out of focus. I assume that there is some mechanical problem with the connection of the EAF to the focuser, I have to check it before the next astrophoto session.

M51 is a very common and prominent deep sky object. "M51 is an interactinggrand-designspiral galaxy with a Seyfert 2active galactic nucleus.[5][6][7] It lies in the constellationCanes Venatici, and was the first galaxy to be classified as a spiral galaxy.[8] Its distance is 31 million light-years away from Earth."
