  1. You can however the scope needs a lot of in-focus to use a reducer. Similar requirement with an SCT.
  2. Snap to focus, easy to focus or the range over which scope is in focus is short?
  3. The LZOS does snap to focus and stay's there. Where as with a the F7.7 doublet I need to adjust more, the focus point is over a shorter range hence hard to find/keep.
  4. We can test a scope on an optical bench, however how the scope responds to environment is going to be hard to replicate and we’ve not even mentioned seeing conditions. I’d suggest that’s the variation being reported…
  5. Tak and Vixens scopes cost around the same in Japan, the price difference is on treasure island. One question around the focusing in the doublets you have used, does the FS128 keep the subject in focus other a greater range compared to the Vixen doublet? I find my LZOS triplet easier to focus as it’s focus range is greater then doublets I have used. e.g., on Jupiter I would have to adjust the focuser less with the LZOS compared to a doublet.
  6. According to Markus lens design not changed since Thomas Black original design. And lens material, well we have measurements for that. One thing I would state is that other manufacturers have been increasing there tolerances, e.g Stellarvue is now fabricated in house Strehl 0.99 lens whereas LZOS has not followed suite as would add at least an extra $1000 per lens. It’s not the lens material but figuring the lens. We could also include the C-F correction for a scope. Also the PV of a lens, if you have a high Strehl and a high PV which do you priorities, you want a smoother lens as well.
  7. Lol, a bit like items from Baader, it will be next week, then next week…
  8. The only other Taks you need are a TOA and a Mewlon, then you have almost full house!
  9. Also what weight do the drives support, presume its 20 kg's on both sides? How much do the drives weigh?
  10. Here some competition then, the vixen half pillar is a lot lighter (1.8 kg) and easier to attach... However it's cast I believe, Japanese like to use this approach...
  11. Any news on the new half pillar Derek is putting together?
  12. Anyone here any experience mounting a Newt on an AZ100? On CN I've seen a 115 cm Newt mounted on there AZ100 and that looks possible. The Newt options I've come up with are: BS 10" (length 95 cm) weight 11.5 kg BS 12" (length 110 cm) weight 18 kg. My main concern for the 12" is the weight however the extra aperture would mean not needing a larger aperture for some time. I already have a AZ100 so why buy a Dob mount, especially as I have push too.... Why not buy a Dob, well these are Boren-Simon Newts and run at F2.5 which is great for NV usage and can be used in prime mode so no long stack attached to the focuser. Thanks
  13. Serge needs to have a physical scope tech zero present to make a set of encoders. So it's a nope at the moment.
  14. If theory it would hold a TSA-120, however in practise no, just a little to heavy. It's really aimed at Japanese market for holding 4" Vixen/Takahashi scopes
  15. Slo-mo? If only the Scopetech Mount Zero had push-to.... Looking at a lot of the comments, maybe another thread, whats the best grab n' go setup. 1) What's the lightest setup you find usable? 2) What's the largest aperture you can use as grab n-go? Two trips is grab n' go?
  16. Very true. Open question what's the lightest's alt-z mount you can use with a Nexus and carry a 4-5" APO?
  17. Bag, it’s just easier. Takes 5 seconds to put finder on/off.
  18. My Avalon T-Pod tripod, means I can carry my mount and scope into the garden in two trips. Makes the setup grab and go, setup 5 minutes. Without this I would not go out on nights that could go either way with regards to cloud cover or seeing:
  19. The 130 I have are star light, Rupert wanted them to match the anodising of the FT focuser. However the weight is more, I’m sure I could get lighter, but finding them is hard…
  20. You might be able to use the KUO handle, ask APM if they have any spare.
  21. @GavStar you will need a hoist to get that down from the top room, time for an obs? Of course we could ask @Tyson M for pointers as he is a bit of an expert on this. APM max load mount on order?
  22. You might see some "dimming" around the edge when using EP's with large fields stops. I believe the CN thread you referring to is here: https://www.cloudynights.com/topic/499161-c11-edge-07x-reducer-visual/
