So I was able to get the adapter printed along with the M54 tilt adapter that I ordered, we got a solid clear night while down in Southern Utah on our trip so I tested it out with my 2600mc Pro and a Voigtlander 50mm APO lens. I definitely need to dial in the tilt a little bit more, but the lens is so wonderfully sharp and mostly aberration free that even with the tilt the images turned out ok. I think the adapter can be refined a little bit in some spots, a little longer and adjusting the widths/lengths of some of the right components to tighten it up, I'm also going to try printing it with a different filament to see if I can make the threads a bit more robust, but all in all I like having the small ring adapter for each lens versus changing out the tilt plate every time I wanted to use the camera on different optics/mounts. Here's a pano I did with the setup:

 

2 minute subs at f2.2 and gain 100, 22 subs for the sky and 13 for the foreground:

I wanted to know if any 3D design was successful with ASI cameras??? Así071 or así2600

Did you not read any of my reports in this thread?

[Joball23]

i'll definitely send you one for testing when i tune up design to make a good fit. Several hundreds of people downloaded my models but none reported but you. Who else I can ask it for? 

Due to recent job change, life got a lot busier than before so progress is very slow though. And I don't have a lens. Why am I keep developing this? 

 great friend, what a good publication, your 3D design that you have done for the 6mm ASI cameras (ASI 533, ASI 183, ASI 174, ASI 294) is very good... I think that with this it solves the problem of not firmness simply and quickly

friend I have already read the entire post, writing down information and I see that you managed to print one in M54 and inside it is a sony mount, only that I am not clear, so you put a spacer from M42 male to M54 female and inside your 3D design ?  .... is this how I understand it?  ...this for ASI 2600, ASI071... cameras with 17mm sensor distance

I am interested in a Sony E mount to QHY268M adapter. I have acces to a 3D printer and can design in Fusion 360. I have the camera and the lens but lack the understanding about the measurements and correct back focus. If anyone is willing to guide me in designing this adpater I'll give it a try.

Nope, the 3D printed adapter with the M54 threads screws into this: 

 

https://astronomy-im...nsor-tilt-plate

 

You want to replace the tilt plate on the 2600 or 071 (which has m42 threads) with the tilt plate which has m54 threads (that plate comes stock on the full frame sensor cameras, the 6200/2400). The flange focal distance on an E-mount lens is 18mm, you just need to adjust the tilt plate until the distance between the back of the lens and the sensor is 18mm, it doesn't have to perfect (within 0.5mm is perfectly fine, as long as you don't go over 18mm, if you go over 18mm you won't reach infinity focus). You can also 3D print the tilt plate that Jinux made and just use that, but then you have to swap the tilt plate out when you want to attach the camera to different optics (like a telescope or Nikon/Canon lens), with the m54 tilt plate you have a lot more options for just attach the camera to various optics, you just need to incorporate an m54 adapter.

Earlier in the thread someone already started making an adapter for the 268M, I'd reach out to them.

just great!!!!  friend can download the 3D design for cameras with a distance of 6mm jinux (thank you very much for that) .... but I did not see a link to your design for cameras with a distance of 17 mm would it be too much to ask that you share it with me?

I'm wondering if another approach to attaching a Rokinon 135 F/2 E-mount to ASI cameras is to remove the back portion of the lens. Would that reveal a Canon mount? I have other 3rd party "E-mount" lenses which are just their Canon mount version with a Sony E adaptor attached. I just thought about trying this with my Rokinon E-mount 135, but the 4 screws holding the "adaptor" in place are not budging. Has anyone else tried this?

just sell it and get the cannon version, then you can buy an m48 thread to replace the canon mount and you have a lot of backfocus.

 

I did that and added a filter drawer, but honestly the 135 f2 just isn't that good for my standards and has a lot of CA, bright stars look weird and deformed, and it's overall not sharp enough to take advantage of small 3.76um pixel cams completely. it's good for the price as a beginner lens but I should have moved on  to something better a while ago instead of attempting that project. 

 

 

not sure on a better option yet the voigtlander 110 is interesting I just don't like the short infinity focus throw of the macro lenses if it is like the 65. I had the 65 macro and mine wasnt great and it got sold. the 35 and 50 were good though.

Better than nothing but only supports "small sensor formats" and "manual lenses" though.  The opening is M42. 

 

I have five Sony lenses, none of which are manual, and one ASI camera which is full frame.

Hello!

This thread is really interesting and though I don't have an astrocam nor an e mount lens, I would like to suggest something.

There was mentioned a problem with the tilt plate designed by jinux. I think it should be possible to make an exterior "skeleton" to hold the camera and the lens together as rigid as possible and that woud free the load on the tilt adapter thus dimming the tilt problem.

Also, by using a skeleton, it should be a lot easier to place a filter between the lens and the sensor (maybe more like the 31mm or the 36mm ones). I don't think it was mentioned in the thread but by placing the filter inside the adapter, the focal plane shifts a bit towards the sensor (around 1mm, depending on the filter) so instead of 18mm, you can work with 19mm, which might help a bit.

Biggest con would be that you would need a different skeleton for each lens, but I think that's manageable.

What do you think?

Any feedback on Eric's E-Mount to M54 adapter?

I think it's great idea and now my CNC is set up properly, I'd like to make one in Aluminum and try.

Just tried M54 thread cutting on hardwood to check program and fit. It is good to go while may need to adjust bayonet side fit. I want really tight fit on this side.

I have following two questions.

1. Depending on M54 thread start point (lead in), lens can sit on 2600 camera in different angle than normally anticipated by bayonet. Would this cause any problem?

2. How do you remove it? By nature of screw in, people usually tighten it and there is not much place to grasp to turn it back. I'm thinking designing a remover using bayonet blades. 

[Jinux]

BTW, for the people who has QHY268, take a picture of sensor side of the camera and post here. I might be able to come up with some design.

I can send a link to the 3d 3mf file for the adapter if you want to give it a go. My thought was to have 3 holes along the side of the adapter to incorporate grub screws to "lock" the adapter on a lens, but I actually ended up selling my 2600mc Pro (dang kids are expensive and needed some extra money) so I never got around to designing that part. The bayonet side definitely will need some trial and error changes, I found that the bayonet side was where most of the printing error happened which resulted in tilt problems.

That doesn't look like it's big enough to get correct backfocus.

 

I've also designed adapters for the ASI planetary cameras and also for the DSO cooled ones. These are for Canon lenses but I can upload the files for anyone to download and measure exact distance from flange to lens and use them to design for other mounts. If I recall, there is 5mm difference in the adapter between the planetary cameras and DSO cooled cameras, the same adapter won't work with both.

 

I will upload tomorrow and post details.

This is example of the one for ASI DSO cooled cameras:

I just ran across this post. Very cool. I am trying to connect an ZWO 294 cooled camera to a Rokinon 14 or 16 mm f2.8 lens with a standard Canon EF mount. ZWO makes an adapter but their support people are very quick to say it won't work with non-canon cameras even though I think it might. Would you happen to have anything that might work for this?

Thanks

[Jinux]

With some trouble, I was able to machine the piece.

M54 thread fits well but bayonet needs improvement. I made it too tight.

With all busy work and occupied weekends, I don't know when I can finish this project. Haha.

Nice, looks great!
Just in case, I can beta test in case you want, I am located though in Greece.
Got a Samyang 135mm that turned out to be great and would like to use it with my 268c

Found this thread while looking for answers to my situation...
I have a Tamron 70-180 2.8 lens I'd like to use with my ASI 533MC Pro.  With the ZWO adapter, doing the math, I'd be right at 18mm. Can someone else verify this is correct?

 

I can remove the 11mm ring on the 533, which leaves me with 6.5mm of back-focus.  The adapter is 11.5mm according to the reference guide, so I think that means I can connect the two?  If this seems sound, my next issue is mounting the lens to the AM5 mount...

Has anyone had success mounting a Sony E-Mount lens to the ASI 533MC Pro?

that's quite interesting curious if you got further

 

 

after frustration with MILC cams I keep coming back to this. A 6200 would be nice...

Did anyone try this on an ASI 2600 Cam? How much vignetting?

It does not work with an ASI2600mc, the 2600mc has 12.5mm of backfocus distance WITHOUT the tilt plate, the ZWO adapter is 11.5mm thick, that brings the total distance from the rear flange of the lens to 24mm which is well beyond the required 18.5mm flange focus distance of an E-mount lens. This is why I made the adapter above, Jinux machined one which looks quite nice, I 3D printed mine and it worked well enough when threaded into the tilt plate (see my post, #76, at the top of this page for an image I did with the 2600mc Pro and a Voigtlander 50mm APO lens). Keep in mind with that adapter you need the M54 tilt plate, the stock M48 tilt plate does not allow enough width to fit an adapter on an E-mount lens. 

 

The ZWO adapter is only for "smaller sensor formats", basically anything smaller than the 2600mc cameras.
