yes my observatory in the corner. will post a article and pics for you maybee today as ive got day off due to material delivery problems.
must check that camera is square in focuser ive had that thappen before. i noticed a drop in image quality during evening but put that down to altitude of object which went from 58-40 deg. if the focus changes during the evening due to temp drop does it move in or out?
one thing i am having trouble with is a very slight drift during exposue 3-4 pixels in 6 min and its constant during the whole length. do you need the giude star to be in the same field as the pic as i assumed it shouldnt matter give everything moves at same rate together., i suspacted my polar alignment to be a smidge off possibly (using losmandy pole finder which is accurate as far as i can tell)but it seeems to happen consistently. im using guidedog ed80 guidescope but the guidestar holds steady for duration. the plate holding al the gear is solid architectural alloy which is twice as strong as normal aluminium, so not expecting any movement there, rings are tight.... hmmm puzzling
8 exposures @360 secs 800 iso, 5 darks at same, standard off the shelf 350d with 12 inch newt
