  1. For the off chance, looking for an Ayo II mount in excellent condition. thanks andre
  2. Hi Robin, i would need 1.5" for the top dust cap. The 2 links above look interesting, not sure how deep the caps are to hold on tight.
  3. I was hoping for an easier solution
  4. I spent the last couples of days looking for 38mm (1.5”) eyepiece caps for my Tak LEs. surprising how hard it is to find something as basic as this . Does someone would have a pointer where to find a handful?
  5. I still have the original Ayo Traveler mount, worked like a dream with my ED100. For anything bigger the Ayo II would be perfect
  6. Thats a good start i am happy with Cheshire/Catseye collimation, just wanted to confirm that i use the right mark on my primary to do so. Now i just have to work out what the difference between infocus and outfocus star image means. I am visual observer only and generally happy with the views, but interesting to see if my OO mirrors live up to premium you pay.
  7. Thanks for the link alacant, by the sounds of it, when collimating the scope with your primary spot (which is my Catseye hotspot) and the star image is not asymmetrically skewed than you primary spot should be placed reasonably correct.
  8. It has been a while since my last post, as i don’t seem to have the same spare time I used to have. I decided a while ago on a simple setup, a 10” OO dob with binoviewer for longer sessions and a 6” OO tube on a small photo tripod as grab and go scope. Both with their top spec mirrors. To help with collimation I got Catseye primary sticker for both, and in both cases found the existing primary spot (which I wasn’t able to remove – but I didn’t try to hard) to be a few millimetres of from the Catseye spots. It has bugged me since then if I placed the Catseye correctly. Yesterday
  9. do they only work as pairs in binoviewers ? - edit: should have read you report first ! I was kinda hopping I am all set with my 3 Tak LE pairs
  10. I use my 100ED f9 only for planetary with either a Take LE 5mm or TV 6-3mm To make life easier with my alt az mounts I would grab a Tak LE 30 and 12.5mm for lower mags. (There are better and more reasonable choices out there, but I have them anyway for my binoviewer. Better eye relief and form factor then TV plossl)
  11. Good idea, I try this, is not much I need. Just thought after investing in the oo scope and collimation tools I try to get it as good as I can
  12. Thanks Shane, yes the washers did the job. Was a bit worried they might leave marks on the tube but what can you do. Yes it is a oo UK scope. The ring on top of the ota is round so I took it from there
  13. I followed the instruction that came with the cats eye set. I think flo has the book as well (new perspectives on Newtonian collimating) I only started as I couldn't properly centre the secondary in the sight tube. It was offset to the right so it kinda made sense to lift the focuser slightly in the right side.
  14. After receiving my new dob I went out to order the cats eye kit and then took the ota apart to instal the cats eye dot on the primary. While I was on it I thought I might as well flock the upper and lower part of the tube. I then started the collimating process, making sure the 4 spider vanes are equally long (tick), the focuser is perpendicular to focal axis (holding a ruler in front of the Cheshire and on the opposite side of the tube, tick). Then I inserted the secondary screw on its own and checked if the cross in the Cheshire lines up with the screw to see if the focuser points towards th
  15. Still debating the best way on how to improve on my 100ed / Quark combo. I got a TV 40mm plossl to get the magnification down and would like to go a bit lower. As a reducer in front of the plossl wouldn't help with the small fov I rather try to use a reducer in front of the quark. I saw a picture from Stu, he had the Orion 2" 0.8x in front of the quark. the 0.8x would get me down to an fl of 7.2, still within the recommended range. Looking for recommendations for a reducer with filter thread to fit my 2" UV/IR cut filter in front. Idealy with a 2" nose piece and a T2 thread on the other side
