M20 with GSO 10"RC and QHY10

Finally managed to get all my equipment in order with all the required software and as a test image I did 27x5min subs on M20. From the suburbs its difficult to get all the nebulosity etc surrounding the object so I may attempt this at Astrofest with this scope. Im pleased with the camera which has a few idiosyncrasies. The major one is that bias frames must be taken at the time of imaging due to the way that the chip downloads the colour wells to different sides. If this is not done correctly then a colour gradient results which is difficult to remove with flats etc. I found that I have a tilt in the chip and must check this with another camera as Im not sure whether this is from the chip plane or the scope itself. The field is quite flat apart from the tilt as I used Als Collimation tool to check a defocused star and that shows really good collimation. Thanks again Al (Sheeny) as I find your programs really helpfull.
I must add a note here that Theo of Gama Electronics went to hysterical and heroic efforts with some initial issues with the camera. I cannot recommend nor praise his attention to the needs of the amateur more highly.
Thanks again Theo but you need a public acknowledgement from me.
Comments welcome.
