I only have room in my life for one lovely refractor, so one must go. I have acquired a Takahashi, so my beloved and well cared for William Optics Zenithstar SD66 has to go. It is optically perfect with no scuffs or scrapes. Has been used as a guide scope and astrograph on my LX90. It comes in its aluminum flight case. OTA only.
Price is £280 or 325 euros, to include postage within the EU.
PM me if interested.
Hi Everyone, need a little help choosing the right flattener/reducer for the William Optics Zenithstar73.
I am after one that does both jobs so that rules out the dedicated Flat73 which is just a flattener!
So I was wondering if I could get away with the Flat6 0.8 reducer which does say it works on scopes 70 - 80mm f/6 but doesn't list the ZS73 in the models list or do I need to spend the extra and get the Flat6A11?
Can anyone shed some light on this have email 365 where I have seen the Flat6 but had no reply.
Thanks in advance.
As you can probably tell I’m brand new to the community. While I’ve been passionate about space related topics for my whole life, I’ve finally taken the leap and I’m about buy a simple astrophotography rig. Ive done a fair bit of research and, like many, I’ve decided that the William Optics Zenithstar 61 APO refractor is best suited for my situation. I plan to use my canon 600D/T3i as the main imaging camera and I also plan to use the Skywatcher Star Adventurer as a tracking mount for this scope. However I have a few questions:
1: I seem to be confused about how I should connect my DSLR to the Z61. As far as I’m aware, all I need is a T-ring and the WO Flat 61 Field flattener and I should be good to go. Is that correct?
2: will I need a dovetail bar to mount the Z61 to the star adventurer? Or can I directly mount the z61 to the base of the star adventurer? (This was demonstrated by Trevor Jones from astrobackyard with his Z61 and the ioptron Skyguider Pro.)
Sorry for such a long thread; I’d just hate to finally get all my gear together and find out that some gear is incompatible.
Thanks for the help!
