Thanks for feedback sil.

You got me a bit worried now since I was imaging at native f10 on the night (not using any additional lenses in the path). My LX200 is brand new and this was my only second outing / first imaging session.

On the first night out, having been late with installing Kendrick dew cap, I got some moisture forming on the corrector plate around 2am. I promptly put the main dust cap back on and brought the OTA indoors. Last Saturday night I shone a torch at the plate and discovered to my horror that it was covered by a lot of fine dust! Tried blowing some of it away with the hurricane blower without much luck.. Don't know if that first night's dew coupled with Canberra's spring pollen are the culprits.

Can condition of the corrector impact image quality in this way?

NB I have not tried taking day time photos with the SSSSI yet, will give it a try when the dusty season's over..

Thanks, I will try searching for these online.

I was running out of the box, unmodded version of AMCAP. All I have done is checked the Low Light option, lowered exposure setting to 4 and increased the Gamma slider to around .8. I think I will give SharpCap software the go next time as I do not like the way AMPCAP allows you to overwrite previous capture files without warning. I must have done it about three times before realising what was happening!

This camera has a lot of quirks, the biggest of which seems to be focusing as discussed here..
