Description

-20C

Too cold to set up autoguiding (I aint crazy).

Shutterboss intervallometer refused to function, so took the shots manually

Around 40 mns total time

But 25% turned out bad (very low scores on DSS: star trails...). The manual remote shutter has to be manipulated very cautiously (thats my conclusion, because excellent subs and very bad subs are mixed at random...)

Just took 4 darks... Turned out that closing the scope and reopening it condensed some humidity, so I had to quit after taking a few darks.... But I looked at the darks and frankly there is very little noise

Processing : Just DSS and basic stuff in Photoshop Elements. Got to buy Pixinsight !

Frankly I am really impressed by the quality of my Esprit 80mm refractor !

And a word of caution: Left the tripod in the trunk of my car. When I got home I got all my stuff inside. Went in, removed the multiple layers I had covered myself with and decided to store the tripod. Bad mistake: when I touched it, it really burnt me .....
