Aren’t the Meade HD60 eyepieces supposed to be essentially the same as the X-CEL LXs?

Divine intervention perhaps. 🤔

Which version? The Altair.

Found this on a Australian dealers site.
** Please note the release of the Sky-Watcher Evolux range has been delayed and according to Sky-Watcher’s Australian distributor availability is now December 2022 **

Found the article on calculating the size of the alt bearing and added it to my earlier post.

I think the bigger the better more or less but this article gives the calculations to work it out.

While the SW 180 mak is a good planetary scope ypu might also consider the GS0 8” Classical Cassegrain. Used to have the 180 mak but replaced it with the 8” CC. Find it has the edge over the 180 in on axis sharpness and resolution.and has a crayford focuser and fixed primary (no mirror flop). Great overall build quality and will take about 500x mag on the moon when seeing is good enough.
Classical Cassegarains used to be very expensive and hence you didn’t see many around but now that GSO has brought out an affordable version it is rapidly gaining in popularity.
I have both the 8” CC and the 6” CC which is a grab’n’go scope.
My 8” CC along with a 125 APO.

No the TS says comparable to FPL53
“Triplet Apo Objective with two special glasses (Lanthanum glass and FPL51) - Ohara Japan - colour correction comparable with FPL53 triplet objective”

Same as the TS 115 triplet except for the focuser and rings.
Or the.

There is the StellaLyra Classical Cassegrain as well that is rapidly gaining a strong following.

Opticstar are the new UK importers.

The Concentre is one of those bits of kit that become an essential for setting up a newt once you’ve used one. The Cheshire is a lot cheaper of course so very popular.

I would recommend a Concentre for setting up the seconday properly. Will get your secondary perfectly centered and set up. Tried all the other methods and none was as accurate as the Concentre.
The Hotech is about the cheapest good laser collimator around. Used one after the Concentre and got great results.
Many will come along and recommend a Cheshire eyepiece but I’ve found it’s better than nothing but a poor substitute for the Concentre.No where near as accurate.
The Howie Glatter collimating gear is excellent but expensive.

Secondary mirror can sometimes dew up if dew is heavy. Kendrick makes dew heaters that fit RC secondaries but are bringing out a new design in Feb so temporarily unavailable unless you can find a dealer with stock.

So all you want is a rail under the scope with a motorised weight that automatically moves to correct balance when you change an eyepiece. Simple. 😁😁😁

Are there any updates on the AZ75? I heard it was being tested by a couple of members, I'm curious!
I’ve heard it is close to release so hopefully not much longer.

So will the AZ100. Can disengage the clutches and move the scope from low angle to vertical and it stays there.

Set the alt and az clutches slightly loose and the alt lock completely loose for now. Found having the alt clutch in particular overtightened isn’t good for smooth movement. I can move the scope from low angle to vertical and it stays balanced. You don’t have to have the clutches fully tight to use the slo mo controls. You should be able to move the scope easily by hand as well as using the slo mo controls.
I suspect some of the other adjustments have been played with.

OOUK VX16 refurbishment
in Discussions - Scopes / Whole setups
Posted · Edited by johninderby
When I had my 14” OO I glued an EbonyStar ring onto the base and movement became perfect. The ptfe pads that OO use are good and don’t need replacing.
Pity the EbonyStar rings are no longer available from Telescope Express. 😢
