Hi Robin, I've been following this thread along, but may have missed this comment from you. My question is: What mount do you intend on using? If you intend going to a AP900-1200, I would seriously

Hi Doug, (And the group) Sorry that I didn't notice the 4 latches per case. You are correct, this should be sufficient. If anyone would ever be in doubt, Under the most adverse conditions such as

I haven't given him a design incorporating some of the suggestions here. So, I don't have a good estimate for what I plan to do. The original design was estimated at around $75.00 ea. for eight bars

Fair enough, Robin. I have made inquiries elsewhere, from a group having several expert astro-imagers (some of whom are also on this list) and if I am able to find reliable information about

In my first message I outlined what I thought to be the possible consequences of flexure in the bar. 1. Go to pointing inaccuracy -- To test whether this would be a problem from flexure you would

I feel confident that the mount would be quite safe. The case on the other hand may be dented. I encourage you to talk to Thermodyne about those concerns. Ask to see the qualification data. Please

Hi Robin, Yes, I did read Bob's message, but I find nothing in it that suggests he tested it under conditions of use; i.e., actually measuring flexure during tracking. Lifting the scope up by the

Did you read Bob Luffel's message? From what I understand, the hollowed out bars have not been produced very long. Bob's description sounds like he did test it "under conditions of use." From Bob

I guess Roland just did! I stand corrected!! :-) -Ray

Hi Mike, Yes, I'm aware of those commands. I thought the "guide rates" only applied to hardware guiding from signals given through the cable connected to the mount. But, the button commands (from

Thanks Mike. Looks like a winner. So, if I understand all of this correctly, I can make my board so that I can use MaxIm serial commands for guiding an AP-GTO mount as follows: 1 - send :RG0# -

The firmware also supports 0.25x, 0.5x and 1x. These are referred to as "Guide Rates". Referencing the Astro-Physics command set, these rates can be set with the :RG0#, :RG1#, and :RG2# commands

Hi Doug, and all, Now seeing the actual cases, I do have issues, questions, and uncertainty, that I'm going to have to address to Thermodyne. First, the size change, and integrity of the cases: I

I forgot to acknowledge all the effort and work by Mark D'Ambrosio for bringing Thermodyne to my attention and getting the case design going and negotiating a group discount for us. Thanks
