QHY163 + QHYCFW2 Canon/Nikon Lens Kit
« on: January 12, 2017, 03:10:07 am »
Hello,

          Many people ask us to make the QHY163 + QHYCFW2 with Canon/Nikon lens adapter. Now we have finished it. Here is our solution.


          This is a universal kit. It gives the freedom connection method.In this kit , we have designed two connection method. 


Method 1:  Big M42 or M54 screw connection

To minimize the distance between QHY163 and the color wheel, First you need to take off the "fast installation ring" of the QHYCFW2-S

Now there is a M42 female screw on the QHY163. Just screw camera into the QHYCFW2-S

With this setup. The back focus of QHY163 sensor to the QHYCFW2-S front surface is about 26.5mm


In this condition. The front to nikon/canon lens should be 20mm or 17.5mm

Due to camera and colorwheel connect by M42 screw. The disadvantage is the camera orientation may not just be zero degree or 90 degree for the center line of the color wheel

Here is another connector in this kit, called small screw connector. This connector use four M3 screw to connect the camera and colorwheel.

This is the small screw connector

Install this adapter on QHY163  Please note there is some glue for the air proof of the heat board. There is a slot on the small screw connector . You should find the correct direction to install it.

To connect the camera with the colorwheel. You need take the disk off and install four M3 screw. Here is the installed setup . The advantage is the camera sensor orientation is in the symmetrical position and also the screw connection is very solid. The disadvantage is that you camera is connected with QHYCFW2 by screws and you need open the QHYCFW2 to install/uninstall the camera. 

The back focus length to the QHYCFW2-S front position is 26mm in this setup.



Summary:


QHY163M+QHYCFW2-S with big screw connector.  BFL=26.5MM   
QHY163M+QHYCFW2-S with small screw connector: BFL=26MM

And for the QHYCFW2-M-US:

QHY163M+QHYCFW2-M-US with big screw connector.      BFL=27.5mm
QHY163M+QHYCFW2-M-US with small screw connector.   BFL=25.5mm

Hello Qui,

Nice!

Maybe these adaptors will also allow for the use of 1.25" filters with less vigneting?

When will these be available on dealers?

Thanks

Depent on the opening size and F number.

Most 1.25inch filter is 26mm opening diameter, And the QHY163M diameter is 22.5mm. So when F number not so short it should be ok. You can make drawing to see if there is vignetting of your F#


Here is a picture to show this setup with 1.25inch filter

Best regards,

Thank you Qiu,

I mostly use a 200mm f/4 newtonian (stopped down to 175mm f/4.6) and also an SW ED80 with 0.8X reducer, so maybe I'll get away with at least the ED80 :)

One thing I found with my Astronomik 1.252 filters is that the actual clear apperture is only 24.5mm...but I disassembled the filters from the cell and measured a full 26mm, so I found a way to assemble the filters at this full apperture on my 1.25" filter wheel :)

Having this adaptor would be even better though, so I'll place an order with my dealer.

Cheers,

QiuHY

Besides the two connector, we have prepared the spacer for the lens adapter kit.

This spacer is very userful. It has 0.5mm, 1mm, 2mm, 3mm, 7mm spacer. With you can get the length from +0.5mm to +13.5mm each 0.5mm step. (0.5,1,1.5,2,2.5.......13.5mm) This is used for fit any lens back focus. This spacer is very solid and flat.

What are sensor to front FW (for S and M versio) distances with short adapter (that which is connected to FW via four M3 screws)?

Do you mean the original adapter? It should be :

QHY163M+QHYCFW2-M-US=36mm
QHY163M+QHYCFW2-M-SR=41mm
QHY163M+QHYCFW2-S =37mm



This is the BFL of this new kit:

QHY163M+QHYCFW2-S with big screw connector.  BFL=26.5MM   
QHY163M+QHYCFW2-S with small screw connector: BFL=26MM

And for the QHYCFW2-M-US:

QHY163M+QHYCFW2-M-US with big screw connector.      BFL=27.5mm
QHY163M+QHYCFW2-M-US with small screw connector.   BFL=25.5mm


So the new kit is reduced up to 10mm to compare with original one.
