  1. I'm going on this info found online: "The compatible Maksutov-Cassegrains have a baffle tube diameter of approx. 30 mm. In theory, one might doubt that a 2" eyepiece makes sense here. But we can say: it does! If using eyepieces with larger field stops, the image does not become dark at once but slowly from the perimeter to the edge. The human brain can compensate brightness differences up to approx. 15%. As long as an illumination of 85% is acceptable, the usable field stop diameter rises to 40 mm and you significantly gain field of view."
  2. Do I need, firstly, this https://www.firstlightoptics.com/adapters/lynxastro_makcas-sct_adptr.html And then also one of these https://www.firstlightoptics.com/adapters/astro-essentials-2-visual-back-eyepiece-holder-for-sct-telescopes.html ?
  3. Hi Getting confused by the huge array of adapters I might need to be able to use my 2" push in diagonal and 2" eyepieces with a recently acquired secondhand Skymax-127. Do I first of all need a Mak to Sct adapter and then also an Sct to 2" adapter? Any help appreciated.
  4. Hi I'm trying to choose a new scope. I started with a Skywatcher Explorer 130P on the Synscan AZ GoTo mount years ago. I then bought an Orion XT10i dob, which I love, for the aperture and faint fuzzy abilities. Sessions with it are few and far between though but when it gets out to dark skies it's a treat. But now I want to own a frac as well, something a bit more portable for 'everyday' use. I already have an eyepiece collection, telrad, dew heaters etc built up over the years. But I will need a mount for the new frac, it'll be too heavy for that AZ GoTo. The budget for both OT
  5. Thanks for that info Scooot. Great to know that it is possible (but I fear too pricey for me). Cheers,

  7. Whilst collimating my bins I somehow managed to lose one of the four tiny collimation screws. Does anyone happen to know what screws these are eg thread size, length? It was going so well, gradually merging the two images, but then nothing happened even though I thought I was still turning the screw. Doh! The screw had actually come out, lost forever. :-)
  8. Thank you, Peter. Now off to find some M4 5mm screws!
  9. Does anyone happen to know the size of the small, black, flat-tipped, philips head screws that hold the primary mirror cell in place. These are the screws on the outside of the OTA at the end, just above the black "collar" of the mirror cell. Thanks.
  10. Ha ha! Ok. I'm sort of looking forward to the poor weather that I am going to experience at my house over the next few days. May those who don't live in my vicinity have beautiful, crisp, clear skies. Better? :-)
  11. The coming wet weather is the perfect opportunity to treat my baby to some upgrades and mods. My XT10i is to be pampered with: Telrad finder on a 4" riser Primary mirror cooling fan Protostar flocking Bob's Knobs on secondary Moonlite CR2 focuser Fingers crossed it all goes well and my baby will be even more wonderful. :-)
