I am thinking of buying SW Star Adventurer and wanted to know about a feature of it. I know that it can be used with an autoguider but I would like to be able to make corrections manually. I have a Celestron RJ-11 keypad (for RA-Dec) from the early 90's which I used for astrophotography with film cameras. Does anybody have experience with connecting a keypad to the ST4 port. Does it work? would it be possible to short-circuit the electronics?

When I show my astrophotography images to my friends and family they invariably want to know what they are looking at. This led me to wonder if there was a way I could display my images on a single page together with a few notes on the target object as well as few technical details of the capture for those who might be interested. What I came up with a "scrapbook" like page that combines all of these three elements in a single PDF sheet ( or jpeg image) that ultimately I might combine together to form a PDF book that I can share online or send to friends and family. In the meantime, I thought I might post in this thread each page of my work-in-progress towards volume 1 of my Astrophotography Scrapbook.
Any and all comments, observations, suggestions and constructive criticisms will be warmly received.
ps. The pages have been sized to fit full screen on an IPAD

i own an 8 inch newtonian telescope with a focal length of 1200mm and a focalratio of f/6. My big concern is the focal length though. can this newtonian be used for astrophotography or do i need to buy an astrograph so i can start with imaging. Or is there anything else i can do to reduce the focal length or of my current newtonian so i can start with imaging...???
