I did the unthinkable

[AstroAndy]

Hello all

After a long time, I went out again to my dark spot (Bortle 4) to image NGC 2841 in Ursa Major. Finally, after a few weeks, I got all my equipment to play, however, trying to focus an old QHY5 guide cam. thru a C11 OAG (even stopped down to f/7) had me hopping around in triangles (thought I'd reached some semblance of focus during daytime but no dice with PHD at night) So, with imaging time slipping away, and a windy environment,  I did the unthinkable and stuck my guidecam onto the finderscope.

So, here is 4:26hrs of NGC 2841 (Luminance) at 200s (80frames), and 90 flats. Equipment: Celestron C11 Edge HD, 0.7 reducer, ZWO ASI294mm pro, Skywatcher EQ8 pro mount, guiding 9x50 finder scope, QHY5 PHD2.
