Hi Qiu

You did not explicitly mention this in your previous post, but do these adapters also work with
  • the standard medium filter wheel QHYCFW2-M-SR
  • plus the OAG-M

Extrapolating from your provided measurements
QHY163M + QHYCFW2-M-US with small screw connector: BFL=25.5mm

SR should be OK
QHY163M + QHYCFW2-M-SR with small screw connector: BFL=30.0mm

but together with OAG we would be in the 54mm range?
+ OAG-M is 13mm with connector
+ 10-11mm from Canon adapter

Am I missing something, or if this would be true then OAG would also not work with Ultra Small filter wheel?

To put it more simple, my assumption is:
- both QHYCFW2-M-SR and -US will work without OAG
- neither will work with OAG

And any hints on availabilty yet :-)

Best
H

Hello,
         Yes the OAG will add extra 10-13mm for the system. And for the 10mm NIKON/CANON adapter , the total length is 20mm. Looks it is hardly to use the OAG together with this setup. But to consider the lens has short focal .So maybe a miniGuideScope is good for that.

Hello Qiu,

I found this accessory for QHY21 22 23 on taobao.com. Here is link: https://world.taobao.com/item/537334146511.htm?spm=a312a.7700714.0.0.yPKRkQ#detail

It has a screw connector, looks very similar to your small screw connector using in Reply #5 (or Method 2). So, are they the same? Can I use this to connect QHY163M and QHYCFW2 by screws?

Hello,

          They are very similar. This is done by the another factory but I think you can use this also.

Tks Qiu. I live in Vietnam, so I can only buy QHY Products through our dealer on taobao. I did not find any "Big M42/M54 screw connection" or "Small screw connector" (which made by QHY) for my CFW2. Did QHY sell these accessories on taobao?

I'm a little confused by all the numbers in this thread.  What I would like to know is with the "big screw" connector attached to the camera, what is the back focal distance from the face of the new adapter to the sensor?  (without the filter wheel).

Now install the M42 big screw connector onto the QHY163.

Hi,

What is the new back focus of the QHY163 with this new ring? I am interesting in reducing the total backfocus of the camera to couple it with my Takahashi Epsilon 160 (55mm backfocus) and my Starlight xpress filter wheel.

One nice thing about the SX fuilterwheel is that they sell all kind of adapter rings so you can screw the FW directly to the reducers without adding extra steps rings.

Anyway, I hope the QHY163 backfocus could be reduced to 13.5 or 14 mm of backfocus, that would be fantastic!

Cheers,

Jose

I received a QHY163 with the M42 "big screw connector" last week.  As near as I can tell, the total backfocus from the face of the new adapter to the sensor is 13mm.

How Joel,

Thanks for your reply! The big screw connector is T-thread female?

Thanks! That's another nice feature of the SX Filterwheel you can change the connectors to Male/Female easily.

One last question, Where did you buy the "connector"?

Regards,

Jose

What do you mean by "Connector"?   I bought the new low profile adapter directly from QHY.  These adapters were just made in the last few weeks.

Hi,

I am interested to buy the QHY163M with the standard medium size filter wheel for 2 inch filters to be attached to Nikon F mount lens 300mm f2.8 and 600mm f4. I saw the parts list on the webpage to do so. Would like to confirm which setup will work for these 2 lens, parts needed and where to buy those parts. One of question is can we control aperture in this setup?

Thanks
