I'm slowly coming to terms with my new imaging setup, but I came up against a problem last night that I'd like some feedback on.
After my session last night I found all my images has drift symptoms. I was accurately polar aligned, the autoguiding was behaving better than it has for the last week. Its been terrible seeing for a while. Its been difficult trying to guide with the stars flaring so much. I'm using the Losmandy GM-8, with a Meade 8" sct (with mirror lock to help reduce mirror flip/slip) for imaging and the Orion 80ED for guidescope. K3CCDtools V2 for autoguiding and ToUcam for the guide camera. Camera was 300D with 6.3 meade focal reducer.Total weith around 10Kg, about 70% carrying capacity of the mount.
One of the issues I've been having is the guide rings I bought are really poorly made and the guidescope has been known to slip. However when you look at the images the one of the Lagoon the drift is in dec (90 deg to what I would have expected slippage to have produced). One of the Dumbell is in dec and the other is in RA????
All images were taken between 6:30 and 12:00 last night, with the Lagoon taken first and the Dumbell at around 10:00ish onwards.
Any ideas would be appreciated. I'd really like to get this sorted out before the Astrofest next week.
