Description

NGC 6622 data from Hubble Legacy Archive.

Clouds are very bad and am running out of data to process. I decided to fetch the Hubble data.
This data is amazing, and easy to process. I guess there is no light pollution up there. The HLA data is a good way for me to learn how to process different data. One of the difference with my own data, is the high number of dead or hot pixels.

Hotpixels:
If you look at the histogram, you clearly see the dead/hotpixels flaring up as the second blue peak.

From Wikipedia: NGC 6621 is an interacting spiral galaxy in the constellation Draco. It lies at a distance of circa 260 million years. NGC 6621 interacts with NGC 6622, with their closest approach having taken place about 100 million years before the moment seen now. The pair was discovered by Edward D.

Keep Looking up!
