Jones-Emberson 1 (PK 164+31.1) is a 14th magnitude planetary nebula in the constellation Lynx at a distance of 1600 light years. It is a larger planetary with low surface brightness. The 16.8-magnitude central star is a very blue white dwarf (96x15s with darks)

M87 and friends, mag 9.6, in the constellation Virgo. 15 min integration time, various sub exposure in the same stack (4s to 15s), darks, flats and Sharpcap enhancement on the fly.
Because of the moon, it was impossible for me to get the true color of the sky.

Nice! Did you see the jet sticking out from M87? I wasn’t able to see it in your image but maybe you saw it during live stacking?

Unfortunately no, But I do not despair..maybe one day waytogo.gif

 

Leo I, a dwarf spheroidal galaxy in the constellation Leo.The proximity of Regulus and the low surface brightness make it a real challenge to observe it. (7 X 120 s with darks.)

Hi!

Arp 286, Trio in Virgo : NGC5566 (mag11), NGC5560 (mag12.4) & NGC5569 (mag13.7)
Sharpcap 3.2 64bit pro, 48x30s, with Darks (x20). No flat since I changed my secondary mirror (70mm to 82mm) to have a bigger field of full light.
