Thanks for the replies.
I will recheck my DSS regiter settings.and check out the links to Wayne's thread.
Please accept I am not trying to get "the perfect image" , l am just trying to get the most out of what I have and enjoy the simplicity of my setup.
I do my more serious work (hobby ) from a permanent pier mounted scope in a an Observatory.
I am exploring this alt az setup purely as a fun option for club observing nights and while travelling (camping). There are plenty of targets that are bright enough for 20 or 30 sec exposures.
I don't want to get into the alt az verses eq wedge discussion ..... I know the limitations of what I am trying to do!
From what I have experimented with so far , I believe I am either having problems with the DSS stacking settings and/or lack of data in the image. I am still unsure though, of DSS's ability to stack frames with field rotation?
I recently tried to stack 47 tuc, 150 X 10sec subs plus darks. ,FL 945mm, f6.3, .......DSS only registered 1 frame.
