I’ve been using my 8’ Edge HD on an Evolution mount for a couple of years now and I added a wedge to it a few months back. Using SkyPortal with StarSense I’ve never really had any major issues getting it aligned.
Last night I was setting up to photograph Mars and went through my normal procedure. StarSense took its images but, after confirming success with the third plate, instead of just winding up a bit and parking it proceeded to pitch the ota towards the north well below the horizon.
Fortunately nothing snagged. I skipped the ASPA and instructed it to goto Mars and was surprised to find it was spot on (better than usual actually).
Anyone any ideas why it took that nose dive? Thanks.
For sale is my beloved but now superfluous to requirements HEQ5 Pro for £650
It's in a used condition as you would imagine. I've had it for about 4 years and found great success with this mount. Ideal for those beginning astrophotography and also good for visual users.
I'm calling it "deluxe" due to the upgrades I've had done.
- It's belt modified
- It's had brand new bearings and grease
- The backlash has been expertly setup
- It has the latest polar scope
- The power port has been replaced with an aviation style port which is a lot more secure
It'll come with the hand controller and at least 1 counterweight (if I can find the second it'll come with both). The polar scope cover has been lost. The counterweight is rusty as always. There is some marring on the counterweight bar housing as shown in the photos.
It also will come with the modified power cable required also.
Note: the power LED sometimes doesn't illuminate but the mount is still powered (please see the photo with the hand controller).

This is my first post on this forum (although I've lurked in the shadows for a while). So I thought I'd share some of the modifications that I've had done to the new Mesu MkII I received last week in case someone can benefit. Sadly I haven't tried it imaging yet only balanced, slewed it around and read the Sitech documentation to make sure everything is functioning. The day it arrived we plunged into sub-zero temps and snow 😫.
The mods include an extended wedge for some limited imaging past the meridian, and an angled counterweight bar for clearance in the tight space. Some have commented in other posts on the long Mesu CW bar but its necessary to balance the weight of the head (unloaded) and to accommodate counterweights for the significant payload. Once tested I'll be loading this bad-boy with a number of different focal length scopes as changing equipment at 25C below is not fun. I lasted one winter doing this and the automated ESO (Exceedingly Small Observatory) was born.
Has anybody with this mount installed homing switches? The Sitech1 controller has an aux port for this purpose. For me this would be for integration into the ROR control system to prevent an expensive mistake. Eventually the goal will be to monitor for inclement weather and shut down the system safely or automate parking and calibration frames at the end of a normal session. This is a work in progress as I only completed the ROR roof upgrades this summer.
PS That flats panel needs moving. It was ok with the old mount but every inch counts now!
So the little circular bubble level is weak.
But how to improve the levelling stage a head of the alignment stage?
A traditional level like this one
Or a simple multi purpose one like this one?
And we do this on the tripod before adding the mount & OTA?
The mount looks gently curved. How do we check that for level or do we trust the ‘fit’?
Hello everyone, I'm wondering if I could get some help, sort of ripping my hair out a little.
I have the EXOS2 PMC-8 and last night I used Sharpcap to Polar align, I set the mount up as usual and adjusted until Sharpcap said excellent Polar alignment.
So my next step was to do a 3 star alignment I was using a program called Explorer Stars to achieve this, so when I asked the mount to slew to the first star it was way off even in the finder scope, is that normal? So I used the controls to get the star in my FOV and centred it, it was the same for the next two stars way off. so I did the same.
I finished the 3 star alignment and when I asked the mount to find an object the object was not centred it was bottom right of the quick photo I took.
I've made sure all the information is correct by setting my Longitude and Latitude and also made sure my time is correct, the mount is balanced and level and pointing North. I think I'm doing something wrong somewhere.
Also may I ask should my counterweight bar be parallel with the mounts front leg? I have two little arrows on the mount that should be pointing at each other when in the home position but when they are the counterweight bar is pointing to the right quite a fair bit.
I'm new to all this only been doing it for a few months so a lot of things are quite confusing.
Thanks in advance Bill.
