I went for the goto option in the end, I figured.it would be a false economy in the long run to add the RA motors then upgrade to the goto system at a later point.
I'm just at the stage of getting it out of the boxes & ensuring it was shipped with the polarscope as promised, otherwise I won't be a very happy bunny!!!
Hoping to catch up with you guys at the next meet, I've been frantic the last month or so...
Cheers
Andy

We have encountered one mechanical weakness in the bolt-on dual-axis declination motor assembly: the RJ11 connector is on a small circuit-board which is "out on a limb", and so is prone to getting snapped off.
I've just repaired one, by glueing and strapping the connector-board onto the side of the motor-case:

Here's how I did it with the EQ5 I've been fettling...
  • Aim your polar-scope's cross-hairs at a fixed object (a neighbour's TX antenna makes a good target). To reach this you'll need to tilt the mount over to its minimum altitiude setting, and maybe extend the South leg of your tripod too (but then hang onto it so that it doesn't overbalance!)
  • After centring the cross-hairs on the reference-point, rotate the declination axis through 180 degrees and see how far the target seems to move in the eyepiece.
  • Now adjust the three set-screws to "split the difference" between the two target positions
  • Repeat the last two steps until there's no apparent movement as you rotate the declination axis through a full circle.
  • Make sure the screws are good and tight, then check the alignment again.

Is there any big differences between the EQ5 pro goto and the Celestron CG5-AGT?

the only thing I've heard is the CG5 is slightly more noisier when slewing than the EQ but the CG5 has better software.

I need it to be on the quiet side so I don't wake up the neighbours. cheers john

I wouldn't describe my CG5-GT as "quiet" (you could pop round and hear it in action if you like?), but then I've never tried an EQ5-Pro.

The SynScan EQ models are compatible with EQMOD (unlike the Celestrons), so if you'll be doing PC control then the handset isn't needed (in fact Carl bought his NEQ6 without one).

Id not bother with the EQ5 - if you can afford it (and lets be honest, price dictates everything!) i'd go for the EQ6. I thought the EQ5 would be the answers to all my prayers - and it has been up til now - as im looking at observatories etc in the future - my EQ5 wont be substantial enough.
If you want to remain portable, its perfectly fine, but if youre looking to sink it into the ground/observatory - then you need to think a bit bigger.

Cheers Ross, next time you whip it out give me a bell and I'll come round and have a look ;)

@ Andy, its going to have to be portable, no way the other half will let me put up a shed/ observatory in HER garden, maybe a pier but I still have to lug it up and downstairs so its going to be a toss up between them two....john
