From Derek’s post on CN
“We'll be demonstrating the mount at the PAS show in Kettering UK this weekend.
We were also due to attend NEAF in April where we would be showing the mount with the GOTO kit but this show has been cancelled again 😞
The mount is booked in for EMC CE FCC certification at the lab in April, so assuming a pass (never guaranteed!) we'll be in a position to start supplying shortly afterwards.”- 1

What’s that old saying “Horses for courses”🤔

Love my 8” CC and impressed with the views as are many using it and don’t give a damm about the reduced aperture as the scope is still an exceptional performer.
It’s the views through the scope that counts. Had a Celestron C8 and much prefer the CC8”

Have done a similar bearing mod and it did need something to add friction. The centre bolt isn’t enough and the bearing will run rough if over tightened. I used a couple of stick on felt pads to add just a bit of friction.

Nice bearing. 👍🏻
Will need to add some method of friction to provide a bit of resistance to turning otherwise one push and it will spin round for ages. 😁

Just something I read on a Camera forum. The conclusion seemed to be no one was sure which anti-fog solution was safe for a camera lens.
-
Some anti fog sprays can attack the coatings on optics so not a good idea to use them.

That's an “L” of a bracket all right. 😁

Mostly good then with a few irritating shortcomings.
Do wish more dobs used tube rings to mount the tube so you could rotate the focuser round to the right position.
18mm marine ply does indeed make a far better base than chipboard / mdf but would bump up the price of the scope a fair bit but a price many would be willing to pay. Perhaps a deluxe version with a ply base would be a good option.

Coming along nicely. 👍🏻
Getting a bit fed up of night after night of misty moon here. 😢

As SW hasn't said what glass is being used highly doubt it is FPL53 or 55. They would shout about it if it was.
Will be interesting to find out what it is actually is. 🤔

There are good lasers that are spot on as delivered but they cost. The Hotech laser is great but not cheap.
Cheap lasers usually need collimating themselves.

Keep looking at the 10” CC version and yes does look a bit of a beast. 👍🏻👍🏻👍🏻

The quality of the SS60-DS is a bit variable so best to buy from a local dealer who will exchange it if you aren’t satisfied. I had one but sold ot on as it wasn’t a good performer visually although OK for imaging.
Even the regular Quarks can be a bit hit and miss so again buy from a local dealer. The higher end Quark stuff seems to have better quality control though.
Having said that a lot of SS60-DS owners are happy with theirs but just be aware that you might have to exchange to get a good one.

Have you had need to adjust the damping adjusters, John? Can’t say I have.
Nope have never touched mine. 🙂

Stuttering occurs when the scope isn’t properly balanced or the clutches set correctly.
You don’t want the clutches set too tight. You should be able to move the scope by hand or with the slo-mo cables when clutches are set correctly.
You can also adjust the worm mesh if need be.
Note that the damiping adjusters only adjust the friction of the slo-mo control cables and not the mount itself.
