Two weeks after i shot this object with my APO, I did it again with my VISAC.
Same object, same exposure time, same camera, different telescope: Astrophoto: Pelican Nebula IC 5070 – 08/22 – astrography.eu
VC200L instead of ED80sf.
This is the very first test, hard to talk about first light when you a re working with a 20 year old telescope, with my VC200L VISAC. I had really bad seeing and still the 50/162mm guidescope. From now on I ll guide with a 60/240mm guidescope.
