Quote:I'm happy with my Atomic Platform also. After a year the drive circuitry died, and he sent a replacement for $40. So far so good on the new one. The drive circuitry is from a Celestron product. I would like to add wheelbarrow handles, but the platform/telescope setup is not really able to be picked up and moved all at once. There is too much danger in having the platform shift and have the telescope fall over. There would have to be more design put into it to make it easily moveable. Plus the base needs leveling and often need wooden spacers put under some corners, not easy when the weight of the telescope is on the platform. An idea for the Atomic II?Mike

Quote:Yep. I put my PST on a small tripod riding on the platform.
Quote:These platforms can be multi use as well. I have placed my DSLR on a tripod on my platform and was abe to get 2 minute exposures with round stars using my 35mm lens and that was with just an eyeball polar alignment of the platform.

Quote:I built my own platform because I thought it would be a fun project and it was. However, I have put into it about what Atomic sells theirs for. Ed has really good platforms too and he is a master at building them. Platforms are built for a specific latitude and can generally be used within 5 degrees of that, so if you buy one used, take that into consideration.Here is the link to my platform pictures:http://www.flickr.com/photos/jeff-guck-in-die-luft/8257785049/in/set-72157632...
Quote:I was looking at your design and was wondering. Is it made to be adjustable to the Latitude? I ask because it looks like the north and south bearing arcs and guides can have there angle adjustable with those threaded eye-hooks and turnbuckles.

I ask because it looks like the north and south bearing arcs and guides can have there angle adjustable with those threaded eye-hooks and turnbuckles. Yes, the turnbuckles allow for some adjustment in latitude. They are very stable as well. I have not tried it out at a different latitude yet. I believe the comments about COG are true even with the turnbuckles, but the XT8 is not as heavy as bigger dobs so I am not as concerned about that. With other platforms you have to raise or lower one end to adjust for lat. With the turn buckles, you can keep the platform level and still change the lat. The other benefit of the turnbuckle is that you don't need to worry about getting the angles cut exactly for the sector supports.
