Hi all.
It's a new month, time for a new monthly imaging challenge. We hope you take the time to participate and image these objects, and generally discuss these objects on the forums.
I'll make 1 sticky instead of 6, and link to the 6 threads here:
Galaxy - NGC5128 (Centaurus A)
Open Cluster - M6 (Butteryfly Cluster)
Globular Cluster - M22
Nebula - M20 (Trifid Nebula)
Planetary Nebula - NGC3918 (Blue Planetary)
Multiple Star - HN40
For reports & sketches of these objects, please see the sticky thread in the
Space & Astronomy Talk forum.
