Due to an unfortunate accident my SN10 primary mirror is broken. While it was an unwieldy beast and pretty much required a complete rebuild when I got it from the previous owner I really loved it.
My understanding, thanks to discussions between owners of this OTA, is that the SN10 used a spherical mirror. However Meade's representative did not wish to confirm this "proprietary information" after stating that they could not sell me a replacement.
So, I'm stuck with a bit of a quandary: do I roll the dice and attempt to get a spherical mirror constructed? (I doubt that non-parabolic mirrors are routinely manufactured and would probably come at a price-premium). I have read anecdotal discussions that the primaries are somehow "matched" to the schmitt correctors which, I must admit, makes no sense to me as I thought that a spherical mirror was manufactured with a uniform curvature. Thus, without more information, I'm thinking that this could be an expensive and ultimately unworkable solution.
Alternatively, do I cut my losses and replace it with something like a Skywatcher 250P?
Any other suggestions?
Many thanks for taking the time to read this and for any advice you can render.
I know it may be a bit of a long shot but I'm looking to buy a HEQ5 Pro mount or an NEQ6 Pro or something similar. Preferably belt driven but not necessary as can happily modify it. Please let me know if you have anything! Thanks.

I have a Skywatcher Newtonian telescope ( D:200, f:1000) The other day I noticed that the 'O' ring which was attached to the finder scope had broken. After a bit of digging around, I obtained what I believe is the correct size replacement ( 1.5 mm thickness, 52mm internal diameter). However, I can't see how it attaches to the finder scope ! Can anyone offer some guidance ? Many thanks in advance.
Please find for sale my SkyWatcher 250 Reflector and NEQ6 SynScan mount.
The reflector has of course been used and shows sign of use on the outside of the tube but the mirrors show little sign of wear or tear apart from a few dust specks. As you can see from the photos the Scope is in very good condition and all viewings are welcome.
The NEQ6 mount powers up but refuses to move. This may be just an update to the handset or maybe the gears need a touch of TLC due to itself being sat doing nothing for so long. The tripod is missing the locking pin that pulls the plate up against the legs but this will be reflected in the price.
i would like to offer this to the SGL community as I know it will go to someone who will appreciate the kit and do so much more with it than I’ve been able to.
Given the fact I haven’t used this kit for a few years now and I’m also moving house, I know longer have the time or room for it so this is the only reason for sale.
*** Update 26/1/2020
I have purchased a new support shaft for the tripod and I have also got the NEQ6 moving so the motors seem to be absolutely fine, please see latest video attached of the NEQ6 powered up and moving.
Skywatcher 250 - £200
NEQ6 - £450
Collection only from Walsall/West Midlands
Please don’t hesitate to contact me if you have any questions and I will do my best to answer them.
Wishing you all clear skies wherever you are
I own a skywatcher Heq5 pro mount, its awesome!
I just realized the AC wire for my AC / DC adapter is broken (see pic 1). I found another AC wire from an old AC adapter and was wondering if this is ok? I see the gauge wire is bigger though and wonder if it matters?
I am thinking of cutting near the female adapter and soldering it back to the entire length of wire that came from the laptop adapter even though the gauge is bigger. ( see pic 2).
