Description

Rather a short night, got less than 3 hrs of data, struggling between the Vegas light dome and the moon. L-eNhance filter seems like it did a decent job, though! Hope to be able to add to this dataset in the future.
Many interesting objects in this frame, including what looks like a bow shock wave in front of the star at top, a bright trail behind the star left and slightly below center, the nebulosity around HIP 34178 at far left, the little tent-shaped bit of bright blue reflection just above HIP 33953 low left of center, and the bright red variable star HIP 34413 at top and left.
The Seagull head is IC 2177 at right, the dark curved feature to the left is NGC 2327, clusters NGC 2335 and 2343 at visible in the upper right corner.
