Veil nebula is a supernova remnant - an expanding cloud of gas resulting from the explosion/death of a massive star. This image shows only the western part of this large nebula (covers ~6 full moons) which lies at about 1500 light years in the constellation of Cygnus.
Details in Alt text.
Conditions are quite good for astrophotography tonight. Able to get 2 hours on western veil so far. The forecast says clouds by midnight. Hope to catch one more quick target before that happens.
Lobster claw nebula (Sh2-157) is a large emission nebula in the constellation of Cassiopeia at about 11000 light years. It is a stellar nursery and is shaped by radiation and stellar winds from a young massive star at its center.

Last night, took another crack at capturing the supernova SN2025rbs in NGC7331. It shines as bright as the galactic core. Other bright stars are the ones in foreground much closer to us and not from that galaxy.
This image is from 90 minutes of data.
New supernova in NGC7331 (49 million light years away) was discovered last week. I could get only 5x1min exposures last night through the clouds. Even in this crappy image the supernova (above red arrow) is obvious on the right side of the galactic core.
Cygnus wall in NGC7000. Really like how all the details of dark nebulosity showing here.

Single 3 minute frame of the Ring nebula (M57) in Lyra. This is a shell of gas expelled by a dying star. In the cropped version the remains of that star, a white dwarf, can be seen at the center of the ring.
M13 aka the Great Globular Cluster in Hercules is a cluster of several hundred thousand stars that is part of our galaxy at a distance of about 22,000 light years. The little smudge at the top is a galaxy (NGC6207) that is much farther away at 50 million light years.
Last night’s astronomy outing was so much fun! Just three of us with a 14" SCT and a night vision attachment for the eye-piece. We spent a few hours hoping from galaxy to galaxy with a few clusters. And the astronomy chatter was priceless. Don’t know when something like this will happen again.
M51 aka the Whirlpool galaxy.

Planning for May 2nd to 4th for an opportunity to capture Mars in Beehive cluster. On May 3rd, the moon will be close by to be in the same frame.
This group of spiral galaxies is about 35 million light years away in the constellation of Leo. M65 and M66 can be seen face on while NGC3628 shows an edge-on view

Rosette nebula (NGC2244) is a giant molecular cloud where new star formation is happening. It is about 130 light years across and at 5000 light years from us.

Flame and Horsehead nebulae in the constellation of Orion. New star formation is taking place in this region of gas clouds and dust at 1500 light years away.

Made a quick composite image showing Mars before (below) and after (above) the Lunar occultation. I have enough images to make a video but need time to do that.
