Description

First time trying to shoot at native F/10 on EdgeHD 8''. It was hard but I decided to accept the result...
The first night was destroyed by wind completely ;) I tried to collect Lum data at the second night, but it was really a bad decision to use Bin1 (the pixel size of 2600mm is too small for this scope). RGB data was collected at the third night, but 2 hours data was ruined because of dew - I forgot to turn the dew heater on ;)
Anyway, I eventually managed to create an acceptable picture. Hope you like it!

I may try shooting the M51 and Markarian's Chain later this month but I'm really looking forward to the summer when the Milky Way rises.
