Has anyone looked at Orion's website and seen the GOTO upgrade kit for their Atlas mount? I am thinking of getting one to convert my CI700. Just wondering if...
I have seen it and have been following it's evolution since the first beta units were in the hands of amateurs. Stepper system instead of servo (supposedly...
497 Autostar Firmware v40Ee posted at Meade http://www.meade.com/support/auto/Build.zip It fixes the GoTo Comets issue, ..and it has a specific fix for the 10"...
Hi Christopher, If I didn't know better, I'd think you had something against steppers.... The main concern I'd have (for general roboscoping) would be that...
Hi Darren, Hi, Christopher, Although I don't have a SynScan, but I did play around the gearbox-less high-end micro-stepping stepper driving system. One thing...
Darren, Well that is a pretty concise response to the pros and cons. I will have to think about it and figure out the better way to go. I guess I can always...
Hi Robert, You're welcome. I thought you deserved a better response than the ones you originally got. Except for the meade, the Synscan is pretty much the...
Chris, Thanks for being patient. I see what you have for the formula, but where did you derive the 0.01666666 rom? I Verified the count on the teeth as you...
Thanks again so much Chris, Im gonna give it a try tonite. Regards, Terry ... 55 ... [mailto:RoboScope@yahoogroups.com]On ... but ... on ... so I ... anyone ...
I think all the response were good. It is helpful to know some information the details about the orion kit. It would be nice if meade would just sell a...
Hi Chris, Sorry, I own you an apology for that implication. It was uncalled for. Still, I do think the responses he got here were counter productive and...
Terry, You may want to check: File > RatioFormula- variable Spur Gear In the very end of the write-up, there is a brief explanation :-) ccs_hello ... LXD-...
Hi All, I've got the mod up and running with a 497 handset in polar mode using the LXD EQ option on the 497. Can someone tell me how to get up an running in...
OK, still won't goto correctly so it must be me. I've had it. Anyone who wants it make me a resonable offer. If you need pictures just ask. Thanks to all that...
Did you experiment with the numerical sign in front of the axis ratios? Did you make sure not to check or change the scope model after setting the axis ratios?...
Hi guy's, My fork mount for my 18" is coming on and I now have to work out some math ;<{ I have made the worm wheel which is 15.5 inches in diameter (Biggest I...
Chris, Tried reversing the sign, scope mount went reverse of what it should, and I made sure the scope model had not changed. Still no good, won't align....
Microstepping is the key. (msg 5334) Better driving circuit and high-quality stepper can handle fine-grain u- stepping quite well, so can they handle fast...
Can I add: Celestron (now owned by Synta) also has few servo-based: StarSeeker ..... and up, CGE, CPC, etc.) Don't know if the ratio is field-changable...
I already have the steppers and an controller that can do 1/4 steps but I still need to now I guess what is sutable ratio from motor sharft to worm gear (RA...
Tony, (360 * 60 * 60) / (480 * 200 * 4 * belt_ratio) = arc-sec/quarter-step The vaule should be in between 0.2 (fine resolution) and 0.5 (course, but a bit...
Tony, You know Darren Hutchinson has the GPL'ed code and circuit to make the original (EQ6's) quarter-step controller to do 1/16 microstepping and other neat...
Hi Tony, Just as a reference point I use a 256 step cycle (64 microsteps per step) with a 5:1 belt drive, 200 step stepper motor with the EQ6 worm (180 teeth)...
Aah, Terry, I don't like to see someone giving up! What about an empirical approach? When you switch on, bypass the alignment etc. by continually pressing...
Hi again, Terry, astrotk wrote: <snip> ... I hope this doesn't mean that you reselected the 'scope model after changing the ratios. As Chris pointed out, this...
Me again, Terry! If you try the method I suggest below, be sure to set Targets to Terrestrial (<System><Targets>), otherwise the mount will be tracking in RA...
Peter, Thanks for the reply. I did not change the scope type after resetting ratios. I will make an attempt to try what you outlined in your previous email but...
Aagh! yet again! I should have tried this before the original mail. When slewing in one axis with Alt-Az readings, the reading on the other axis will change...
