Description

768 60 secs unguided frames taken during the nights of the 10th and 23rd of March 2021.

Orion USA 250 F 3.9 scope, QHY183M cool CCD, on top of an Ioptron CEM60EC. Aquisition, stacking with Astroart. Processing with PS. On the 10th I have used the Baader 45nm ha filter. On the 23rd I have used the IDAS LPS2 filter. The night of the 10th was very humid. Some frames were not so nice. On the 23rd I had a little problem. After 300 subs the Newton went blocked by the Ioptron Tripier. Some panic. But no damage. First time happened.

Messier 109 (also known as NGC 3992) is a barred spiral galaxy exhibiting a weak inner ring structure around the central bar approximately 83.5 ± 24 million light-years away in the northern constellation Ursa Major. M109 can be seen south-east of the star Phecda (γ UMa, Gamma Ursa Majoris). (Wikipedia)
