I am selling my Meade LX90 8" EMC with many accessories due to equipment upgrade, so this lovely scope needs a new home. All in excellent condition; no rust, battery boxes spotless, all motors function perfectly, holds collimation extremely well (only had to collimate once in the past 2 years), when well polar aligned I have achieved 3 minute unguided DSLR exposures.

I'm having a bit of a clearout to make way for a new project. For sale here are a couple of items that have seen very litle use:
1) Celestron Omni CG-4 GEM Mount + Tripod - £125 *** SOLD ***
This is in generally very good condition. There are a few marks, and scuffs consistent with normal use. There are also a couple of minor (small) patches of surface rust on a few of the bolts and steel legs. It has seen very litle use, and has been in storage for the past few years so it is time to find it a good home. The small rubber tips that go on the very end of the feet have perished, so these won't be included.
It includes tubular steel tripod, 2 counterweights, built in polar scope, built in bubble level and slow motion controls.
Due to size and weight, collection would be preferred from the RG27 area. If you are reasonably local, I would also consider delivering.
Price: £125, but I am open to offers. Payment can be made via Bank Transfer (preferred), Paypal or cash on collection
2) ***SOLD*** Celestron Omni XLT 127mm Telescope ***SOLD ***
Again this is in very good condition, and has been in storage for the past few years and has had very little overall use. A few marks on the dovetail as is to be expected.
It includes a small finderscope, diagonal and a 25mm eyepiece
Can be collected from the RG27 area, I could deliver if you are reasonably local, or can be posted for an additional £8.
Price: £110, but am open to offers. Payment can be made via Bank Transfer (preferred), Paypal or cash on collection *** NOW SOLD ***
Any questions please do let me know.
I popped this topic on CN too but noone seems to know anything.
I came by an old Celestron Ultima 8 pre-PEC. I really like the scope and the mount it may be that I have read too much of Uncle Rod's and other's praise that I feel this scope has some intangible personality and charm.
Circuitry in the base seems to work fine even though the batteries don't hold charge but drive the Ra axis . I have 2 replacement on its way to me.
Now my issue: It didn't come with a hand controller. I know it is not needed for tracking, and I don't have a Dec motor but I find it would be useful for centering in RA and D.A.R.V. method drift alignment.
I was on the verge of making a crude controller out of veroboard and 4 momentary switches that I thought to be correct from the info on various sites, but then I came across an Ultima 8 project that clearly showed the hand controller for my scope.
The pic attached is the one.
I am looking for help on how the dial and buttons are wired in and/or photos of the innards of the hand controller or if anyone knows what else is inside the handbox.
The sources I was going on so far is a combination of the following 3 links:
These of course don't include drive rate rotary switch in the middle and if I could I would really like to to restore the full ability of this mount without spending too much on electronics. Plus I don't want to spend time and effort on wiring something that doesn't work.
Oh and lastly I have no background or experience in electronics just own a soldering station and a whole lot of determination.
Thanks in advance
I am selling a JMI focus motor for Meade SCT's.
It has a replacement controller as the original was lost many years ago. Works fine on a LX200.
Asking £40 for complete unit and controller plus £5 if you need it posted.

lets imagine I wasn't to see a nice DSO about 15' size and I think it should look good nicely framed with a 1 deg field of view in the EP..
Which would give the better (or higher probability of seeing anything at all ) view from a semi urban light polluted home site (e.g Bortle 6)?
a) an 100mm f/6 refractor (fl 600mm) and a 10mm EP (60 deg afov, gain 60x = fov pf 1 deg)
(and exit pupil of 100mm / 60 = 1.6mm)
b) a 200mm SCT with focal reducer to give f/6 (fl 1200mm) and a 20mm EP (60 deg afov, gain 60x = fov of 1 deg)
(and exit pupil of 200 / 60 = 3.3mm)
My gut feeling is that the SCT should give a better view just based upon its 2xaperture - but Im not sure I understand fully the maths why.
Is the larger exit pupil going to result in a better / brighter / more successful view?
Or will the view be 'roughly' the same ?
Or have I got it all wrong.....
