Nebulae and terrestrial objects

During the holiday break, I cleaned up my Google Drive and found an interesting gem!

When I used my ultra-wide field setup with a Pentax lens, I sometimes captured some nebula in Ha together with terrestrial objects. Mostly during focusing or model building.

I like these images as they make these nebula look more connected to us on earth!

The Cygnus Loop over our house

The Seagull Nebula in a tree

"some other nebula" over our house.

I might try to take more of such images.

SH2-170 (The Small Rosette Nebula)

This nebula (which is also cataloged as LBN 577) in Cassiopeia is surprisingly dim. Despite taking more than 50 hours of data, I still had to be very careful when processing it.

The nebula is about 7500 light years away in the Perseus arm of our galaxy.
