GordonCopestake Posted April 28, 2006 Share Posted April 28, 2006 I'm thinking about having a change around in scopes. I currently have a ED100 on a Vixen GP with tracking via 2 MT1 motors but not GOTO. I would like to add GOTO and i have various options. However im finding that as i add more and more weight to my rig im using it less and less. Therefore i'de like to re-evaluate my options and think about getting a lighter rig.Ideally i'de like exactly what i have now, a ED100, with GOTO (and this is the unreasonable request) that only weighs about 10kg. Now the ED100 is apparently 3.2kg, so this leaves precious little for my mount options. Plus a 7kg mount isn't likely to be very stable. However the vast majority of my observing is purely visual and as I live under mag 4 skies im thinking that i should really stop messing around with astrophotography anyway, or at least stick to webcam'ing the planets (DSLR's are heavy!)Now as most EQ mounts require a counter weight this would eat up another 3kg of my payload (maybe a little less), so i was thinking about a AltAz mount instead. Possibly a fork mount even. I've seen Celestrons new SLT scopes and was wondering if these mounts would be solid enough to hold a ED100.Does anyone know of a similar lightweight mount that has GOTO and is capable of handling a ED100?My other option is to exchange my ED100 for a ED80, as I know that the SLT mount will happily carry a ED80 as others have done a similar conversion in the past on Cloudy Nights Forum. (the SLT mount has a standard vixen dovetail)Any advice would be greatfully recieved. Link to comment Share on other sites More sharing options...
