Hi everyone, here's an observation from my home country (Netherlands) in Wieringermeer (SQM 21.1) with my 16" Alkaid and Pentax XW 7mm at 259x
Arp-337.jpg
Very bright and very large with many immediately visible details. Three dark lanes, of which one is very apparent, are seen perpendicular to the plane. Additionally, there is a dark “notch” just behind a mag 15 star. The core is split by the the thickest dark lane and has a very mottled appearance. Stunning!
