alpal,
Focus by cranking the lense to the "infinity" stop (I'll be printing up a focus mask when i get a round tuit, as i do believe it's a smidge off)
No guiding - 65 second exposures. Once i figure out the controller pinout, i'll make up an arduino based PC interface that will let me guide with PHD
Mount should be level, but i'll check that again - i've got three pavers cemented into the ground with holes drilled for the tripod feet to sit in, and i almost certainly didn't check the level before imaging (I levelled it once when it was daytime and cloudy) - i was in a rush after doing things like hunting down a bolt to cut to the right length to fasten the camera to the DIY dovetail plate.
Processing was reasonably quick in DSS - a few flats and darks and some stretching.
There was also essentially no drift aligning - i aligned the camera via eyeball on the EQ head, pointed it towards the SCP, and took some "star trail" images, and adjusted the mount until the stars were circling the "middle" of the sensor
Crude crude crude, i know - but i'd been waiting for quite some time to take some images!, and didn't want to waste the night drift aligning.
