I have the same scope and went with a moonlite cr2 focuser, its excellent can carry a bit of weight and no flex, what I did too is add another tube ring to stiffen the tube around the focuser even though it’s carbon fibre it’s not thick carbon so the tube can still distort from the weight of a camera but if your visual only no need to do that

Beautiful image and really well controlled, what gear was used to grab these fabulous galaxys?

My neq6 has been outside under a telegizmos 365 cover for about 4 years, I just take the cover off every now and then to let it “breathe”, temperature shouldn’t be an issue mounts can take some big temperature changes, take people who live in the likes of Canada who lug their gear out from a heated house outside to -30, I’m glad my mount is outdoors permanently makes setting up a 5 min job

+1 for off axis guiding, I tried for months and months with a separate guidescope on my 10 inch Quattro, differential flexure was my problem, I got a zwo OAG and guiding was much much better

Just to note I have had a couple of nights with my new spring and silicone mod and yes it’s much much better at holding collimation at any angle

A very very slight gap like the thickness of a cigarette paper, the silicone will hold the mirror perfectly well so some never put the clips back in but I like abit of security just incase, best be safe than sorry

The mirror still needs to be allowed to expand and contract during changes in temperature so the sealant needs to be elastic enough to allow this

I used grip bond pro for my 130pds and my Quattro 10inch, that has worked with no issues whatsoever, just ensure the mirror and cell is grease free before you stick

I vouch for the 533mc pro it’s an excellent camera, the square sensor is actually great for framing albeit it’s smaller than you’d like but I’d class ot as the little brother of the 2600, same pixel size etc, the 294 is particularly picky with calibration frames but once mastered it produces quality images also, there is a recent vid on YouTube on mastering the 294 calibration, at least 3 second flats it’s one that’s mentioned

My neq6 had the rubber mallet treatment too for an hour 😂 But all is well once back together and tuned backlash it’s running great

Yep I’d check the Bayer matrix pattern

Some of my favourite things to image and look at are galaxy clusters, I did the Perseus galaxy cluster this week, although not as spectacular to look at as some of our own galaxys show stopper nebulas, there’s just something about these images that gets my mind working overtime, and the fact that the photons took all that time to get to our cameras sensors is astonishing there’s no way on earth that there isn’t any other life out there I refuse to believe it😂 well done for having a crack at this

That’s a lovely image of m42, and from a fellow Quattro 10 user that’s nice to see, you pulled some nice detail in the clouds

this is my first image since doing a few more mods on my quattro 10cf over the summer, including upgrading the primary mirror springs to stronger ones and also siliconing the primary to its cell. its also my first image with the starizona nexus 0.75 reducer/coma corrector bringing the scope down to f3 some call it a poor mans rasa, but adding a 600 quid nexus isnt a cheap accessory 😂 guiding was abit of a pain had to bin a few subs but hey ho taken with skywatcher 10cf reduced to f3, asi 533 mc pro 106 x 2min subs 3 hours ish im quite pleased with the nexus reducer dont think its done a bad job for 3 hours on these faint galaxys please feel free to comment, please bear in mind that this is a jpeg version on here and astrobin as im too tight to pay astrobin for premium that allows larger png files to be uploaded to it so for the moment im stuck to uploading images under 25mb https://astrob.in/lsb1t6/0/

The Ra is constantly on the move so the gears are pretty much always meshed but the dec is fixed until a guide command is issued so if the gears have contracted away from each other slightly widening the meshing it will cause problems, that’s my thinking anyway I could be talking absolute garbage and looking for something to blame 😂
