On the other hand, we don't need extreme accuracy, and most Tue, 14 May 2013 11:29:04 GMT Joe Bloggs http://groups.yahoo.com/group/lunaticoastro_en/message/1093 http://groups.yahoo.com/group/lunaticoastro_en/message/1093 Jaime, It's not meant to be selfish but I don't think you'll ever solve a belt and pulley issue if the backlash is down to some stretching.

The way I see it is 1) gravity engages the gears so that i) movement against gravity has Sun, 12 May 2013 20:55:14 GMT bermassi http://groups.yahoo.com/group/lunaticoastro_en/message/1088 http://groups.yahoo.com/group/lunaticoastro_en/message/1088 WOW, This could be a good solution and I'll try it next time.

I never had problems to center a guide star into my OAG, neither before mount flipping nor after that.

Two different issues here: - first, the Sat, 11 May 2013 00:19:14 GMT Jaime Alemany http://groups.yahoo.com/group/lunaticoastro_en/message/1084 http://groups.yahoo.com/group/lunaticoastro_en/message/1084 Hi Paul, thank you very much for the sincere answer; actually I'll probably add this feature anyway, but of course if there are users demanding it the priority Fri, 10 May 2013 23:56:34 GMT Joe Bloggs http://groups.yahoo.com/group/lunaticoastro_en/message/1083 http://groups.yahoo.com/group/lunaticoastro_en/message/1083 Jaime, I'm not sure how much of a "problem" it is in reality. About 1 degree is bigger than I would have thought BUT the main reason I am (starting to) use a Fri, 10 May 2013 23:07:35 GMT neillm2001 http://groups.yahoo.com/group/lunaticoastro_en/message/1082 http://groups.yahoo.com/group/lunaticoastro_en/message/1082 I have been attempting to interface the seletek focuser with the SkyX. So far the attempts have had negative results.

I can add a "map" of position / angle
