First Light for QHY-8L

Arrived yesterday afternoon & praise be, the clouds disappeared :-)
LXD200 10" @2500mm, PHD guided. No filters. Stacked in DeepSkyStacker then onto PS4.

NGC2070 Tarantula Nebula 15 x 300s subs. Half were taken with the TEC off!!
I did try taking darks but only managed to take 5 & they just added to the noise. (Probably due to the different TEC temps)

NGC3372 Eta Carinae Nebula 4 x 120s subs. Again no darks..

A few things I found out about the QHY-8L:
In DeepSkyStacker the FITS camera selector doesn't load the correct Bayer pattern when you select QHY8. I had to use Generic GBRG.

When using the supplied software EZCAP, the TEC controller seems to be ignored when you start capturing an image. This means if your TEC is at 80% the readout may state a temp of -15ºc (my desired temp) but may well be at -25ºc (Just carried on past -15 until it stabilised at whatever the 80% temp may be) & you won't know until the end of the capture...Moral of this story is to make sure the TEC is at stable temp before taking shots.
