hi rich i have the same camera the moon ,if am use in scope and no guideing then its about 0.200 of a sec iso can be any where between 100/200 make sure you do have a pen and paper handy for when you do get it right if a use the goto mount on high precision works fine for me,if i usejust the camera its imposible for me the 90mm frac a one set,of settings the 300mm reflector is the same i did some wide field shots just on the tripod the other day 0f cassopeia, i used iso 400,manual focus at infinity,(turned all the way to the right the lense) and 10sec subs i did about 30 pics at that with darks,flats and bias its a bit hit and miss its another ball

game when you use the t ring ect so its hard to say but for the moon and telescope its normaly iso 100,0.200 sec

heres a link to some

a lot depends on the conditions on the night

Thanks Todd.

I will give it a go, need to get another battery for it next. Have you managed any shots of nebulae yet, im really keen on getting a shot of the horses head in orion when weather allows, its going to be my second target.

orion is a bit low for me ,theres other nebs out there but a fear the 90mm refractor is not good enough for that and the 12" dob is a no go apart from video and a have no ccd camera just a web cam but it would work may be 3 secs unguided iso 400 ,and alter the iso to suite,what systen do you gave to track?
