快將復活 -- 30cm F4 Newtonian
Re: 快將復活 -- 2nd light
Tried to input different gear ratio value into the Skysensor 200PC controller but still failed to get the correct tracking rate. Maybe I need to disassemble RA body of the mount for a check.
Here is the second light of Jupiter taken on last Saturday evening in YL with this 13.1" Newtonian. But seemed the focus was a bit out and the color setting was way too much incorrect. Really a long road to me to learn how to use Firecap and Astrostakket.
1000 out of 3000 frames stacked, 13.1" F4.5 Newtonian + 2.5x + 462C

Re: 快將復活 -- Sliding roof
At the very beginning, sliding roof was not my choice on the design for openning the sky of my shed. But finally, take it, and what is shown in the pic is just a temporary setup.
Re: 快將復活 -- Shed too small
Due to some issue to be concerned, this shed could not be built to be too large and that results in it looks like too small to that 13.1" F4.5 Newtonian. Maybe the same situation to a 12.5" F5 Newtonian. So, I need to rebuild the OTA with shorter length
Re: 快將復活 -- 30cm F4 Newtonian
Execpt this shed not large enough to house the 13.1" Newtonian, the tracking rate of the motor drive system could not be set to the correct value after several attempts. So, the DIY mount and the Newtonian were moved out and they are replaced by a 30cm F4 Newtonian and a very old mount of Vixen Atlux for operation temporarily until all the issues happened to the 13.1" Newtonian system have been fixed.

Re: 快將復活 -- 30cm F4 Newtonian
Good job!
BTW, can I ask you if you have these Vixen accessories available?
(1) 77237 Corrector PH for R200SS (plus the details of its threads)
(2) 72689 EA 42 to 31.7mm
(3) 72954 DC Ring 60mm to T2-thread or equivalent
Will need details in (1) to check if I need more adapters for my CMOS camera

(1) No stock at this moment, and usually this item needs to be order per customer's request. The thread size is Vixen 60mm.
As there is an adapter available from ZWO for coupling EF lenses onto their cameras (assumed you are using EOS system), with the adapters as shown in the attached pics, the ZWO cameras can be coupled onto the corrector PH.
(2) & (3): I cannot find the items no. with Vixen catalogue. Please allow me some time to look for them.
Just one adapter for coupling EOS camera bodies onto corrector PH Do the same job with these 2 adapters

Re: 快將復活 -- 30cm F4 Newtonian
呢樣嘢就比較急,原來 Vixen F4 R200SS 嘅 coma corrector 係安裝咗入去個調焦筒裡面,唔係外露,所以一定要 Vixen 原裝 adapter,但係我買入嘅係二手貨,無咗個 adapter,用咗 MPCC III 先發覺唔夠 back focus,然後先至知道 coma corrector 唔係喺對焦筒外,係入咗去。
你可以睇片就明白:

而 PH coma corrector 就只能夠用 原裝 72954 DC Ring 60mm to T2-thread adapter. 我已經唔用 EOS,用緊 ZWO/ QHY。
