Cazz Posted November 7, 2013 Share Posted November 7, 2013 Do these ever come up for sale second hand at all? I'm just working out a few thoughts - that won't break the bank with the ST150. Link to comment Share on other sites More sharing options...
Brantuk Posted November 7, 2013 Share Posted November 7, 2013 Last time I saw some come up s/h was about 3yrs ago. They used to be a regular thing every few weeks a while back - but doesn't appear to be that way now...... They went for £75 - but they're only £95 brand new (both RA and Dec together) - I would chuck in the extra £20 and buy new. Link to comment Share on other sites More sharing options...
Perkil8r Posted November 7, 2013 Share Posted November 7, 2013 I've got a spare RA motor and bracket for the EQ5 but not much use without a handset I wouldn't have thought? Link to comment Share on other sites More sharing options...
dawson Posted November 7, 2013 Share Posted November 7, 2013 There was a goto handset on abs for £80 or so the other day, and they appear reasonably often. James Link to comment Share on other sites More sharing options...
+Graham Posted November 7, 2013 Share Posted November 7, 2013 Its not just the hand set you will need if you are planing on going down a goto route. You will also need the breakout boards and they only come with the synscan kit. when you add up all the bits even second hand the £300 price tag on a full synscan kit is not too far off the mark.

Cazz Posted November 7, 2013 Author Share Posted November 7, 2013 GoTo isn't essential - as i have to build my skills up, and we do have push too on the C8 if i struggle lol. It's the tracking I'm in need of more I reckon. Now for probably the dimmest question of all time, would a switch do the job to make the motor work? :-/ Link to comment Share on other sites More sharing options...
Perkil8r Posted November 7, 2013 Share Posted November 7, 2013 Sadly not I don't think. I am not sure but I think they rely on a pulse of on-offs to make them step. Link to comment Share on other sites More sharing options...
xanthic Posted November 7, 2013 Share Posted November 7, 2013 Are you after goto or do you just want RA driven? Link to comment Share on other sites More sharing options...
Cazz Posted November 7, 2013 Author Share Posted November 7, 2013 Are you after goto or do you just want RA driven? Just RA driven. :-) Link to comment Share on other sites More sharing options...
xanthic Posted November 7, 2013 Share Posted November 7, 2013 If you can get the motors, I can build a stepper motor driver. Link to comment Share on other sites More sharing options...
Cazz Posted November 7, 2013 Author Share Posted November 7, 2013 Sorry to be thick, but I don't really understand, I'm currently looking at FLOs website page with them on, and it's not really helped lol. Link to comment Share on other sites More sharing options...
xanthic Posted November 7, 2013 Share Posted November 7, 2013 If you buy the kit from FLO, it comes with a unit that'll drive the motors at the right speed. If you just get the motor on it's own you'll need a driver that sends pulsed power to it, so that it turns at the correct rate. Link to comment Share on other sites More sharing options...
Cazz Posted November 7, 2013 Author Share Posted November 7, 2013 I see, thank you, so that just leaves a hand set or something to make it all work. :-) Link to comment Share on other sites More sharing options...
Brantuk Posted November 7, 2013 Share Posted November 7, 2013 The RA motor comes with a handset when you buy new: http://www.firstlightoptics.com/skywatcher-mounts/single-axis-dc-motor-drive-for-eq5.html Still £75 new I see - that price has held steady for 3yrs.

Perkil8r Posted November 7, 2013 Share Posted November 7, 2013 If Leigh can make you a driver for it, I have the brand new one with mounting bracket and drive gear for the RA slow mo shaft, yours for £20. As I say though, you need to have something to send a pulsed feed to it, it can't just be a switch. P.s. the EQ5 motors (non goto) are 6v Link to comment Share on other sites More sharing options...
