Description

This image is the composition of the image of 23rd and 10th of may (over 12 hours at 60 secs unguided subs with a Orion USA Newton 250 F3.9, a QHY183Mcool on top of a Ioptron CEM60EC) and 4 hours an 46 minutes taken with an Acuter 90ED F6.7 (with focal reducer) and a modded Canon 600d put on top of the Newton. One of the 2 batteries of the Canon had problem during one night so exposures are less than they could be. Subs duration for the Canon is 120 secs with 30 secs interval. Camera is controlled by an intervallometer. Stacking is done with DSS and composition entirly in PS. Thanks for looking

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)
