How to connect ASI6200MM Pro to 2″ EFW/M54 filter drawer and OAG-L?
How many solutions are there for ASI6200MM Pro to get 55mm back focus length?
If you are still stressed with these problems, then this tutorial is exactly what you are looking for.
There are five connection solutions for ASI6200MM Pro.
1. Using adapters only
*This solution needs the M48-M48 16.5mm extender and the M54-M48 21mm extender. You can find them in the package of the ASI6200 camera.
*5mm sensor tilt adapter is attached to the camera.
2. Using 2” EFW
*This solution needs M48-M48 16.5mm extender and the M54-M48-2 adapter (come with the 2” EFW). You can also buy the M54-M48-2 adapter separately.
*You need to disassemble the back cover of the 2” EFW and then fix it to the camera via the screws.
*5mm sensor tilt adapter is attached to the camera.
3. Using M54 filter drawer
*5mm sensor tilt adapter is attached to the camera.
It is much easier to connect to M54 filter drawer than to the 2” EFW with the M54* 0.75 male thread of the filter drawer, as the picture shows below:
Please note that the back focal length of the solution 2 and 3 is 56mm, and the M48-M42 adapter will block the sensor for a little bit as the diagonal of the ASI6200 sensor is already 43mm.
Thus, we more recommend you go solution 4 and 5.
4. Using M68 OAG and M54 filter drawer
*This solution only suits the telescopes with M68 thread side.
*5mm sensor tilt adapter is attached to the camera.
The detailed connecting instruction:
1) Preparation: M68 OAG, M54 filter drawer, ASI6200, and hexagon wrench.
2) Screw off the M54-M48-2 adapter from the filter drawer.
3) Mount the M54 filter drawer on the camera via threads.
4) Connect the M68 OAG to M54 filter drawer via the 4 screws. Please notice that you should keep the prism of the OAG parallel with the sensor of the camera.
5) Done.
5. Using OAG-L and 2” EFW
*5mm sensor tilt adapter is REMOVED from the camera.
This is the very first and also the most recommended connection solution. The combination of the mono full-frame camera and 2” filter wheel can create many possibilities for your astrophotos. The use of OAG-L will also help simplify your imaging setup by replacing the guide scope. It’s very suitable for skilled astrophotographers.
The installation of the OAG-L, 2” EFW and ASI6200 camera is not very complex, but considering you need to remove the sensor tilt adapter of the camera first, so we’d like here to teach the detailed connection steps to help you quickly complete the installation without making mistakes.
The detailed guide of the fifth connection solution:
1) Disassemble the 5mm sensor tilt adapter on the main camera with the help of a screwdriver:
2) Remove the back cover of EFW:
3) Disassemble the filter wheel carousel (Note: Please do not disassemble or move the central screw of this carousel, otherwise the EFW will be damaged):
4) Align the four screw holes of EFW with these in the four corners of the camera chip as shown below:
5) Tighten the screws at the interface between the EFW and the main camera:
6) Install the filter wheel carousel:
7) Fix the OAG-L to the back cover of EFW
Note: You may reposition the prism to make sure it would not block the sensor.
The M2.5*8 screws used here can be found in the package of OAG-L.
8) Fix the 5mm sensor tilt adapter to OAG-L.
9) Attach the back cover of EFW to the front cover:
10) Installation completed.
Note:
*In all solutions, the producing motor side of the EFW(the side where the ZWO logo lies) attaches to the camera.
*Please make sure the prism does not block the sensor or your telescope.
*Adjust the focal length of a guide camera by using the guide knob.
*It would be better if you finish the above steps during daytime, as it is very difficult to adjust it accurately at night.
Can you provide the instructions to connect the ASI 2600MC Pro with the 2″ Filter Drawer (m54) and the New OAG (M68), How to connect for backspace 55 ? The output of the reducer 0.79x being m48.
Can we buy a new m42 to m54 sensor tilt adapter from the ASI 6200MM Pro ?
Thank you.

Sorry the 2″ Filter Drawer (m54) was specifically made to match with the full-frame cooled camera ZWO ASI6200MM/MC Pro. It can’t connect to the ASI2600MC Pro. And the female thread of the Filter Drawer is M54, it can’t connect the M48 reducer. You could use M42 filter drawer and ZWO OAG to connect ASI2600MC. Sorry we don’t have M42 to M54 sensor tilt adapter.

Hi,
I have the same issue.
I use a Tak FSQ106 with 0.73x reducer.
With this reducer and at F/3.6, the basic OAG can’t cover the APS-C format because of the shadow of the prism.
Why don’t you offer the same options for the ASI2600 than for the ASI6200 ?
Could we order the ASI2600 with the M54 tilt adapter in place of the M42 one?
The M54 tilt adapter is not in your Accessories options. Only M42 or M68.
For all telescopes < F/4, your M42 solution isn't correct to cover the APS-C format with the basic OAG.
Thank you.

Sorry we don’t have M54 tilter. You could try move the prism to reduce the shadow. And the occlusion of the prism will not have much effect on the imaging.

Thank for your answer that not satisfy us 🙁
I’m pretty sure that we are many users that need:
– the M68 OAG
– the M54 filter drawer to use ASI2600 with dual-narrowband filter
This M42 solution isn’t viable for all the scopes below F/4.
For myself i use a very expensive scope (Tak FSQ106) and i already use the ASI6200 with another scope (AP 130 GTX). I cannot consider to have vigneting or shadows due to the prism because ZWO won’t provide just a little M54 adapter (this adapter exists and is standard in the ASI6200).
Can you consider our request and tell your technical department to provide the M54 tilt adapter as a standard solution for the ASI2600MC or as an option solution, in fact we need exactly the same options than for the ASI6200 color one.
This is not a new reference to create or a new adapter to produce, all are still existing.
We just need to have the opportunity to use our expensive setups in the best conditions possible 🙂
A big thank you 🙂

+1 for this. 42mm does not cut it with my Epsilon 180ED neither. I have the FW 2″ (for LPS filter, HA filter), the 68 OAG, and then the whole ZWO stack ends in a 42mm peeping hole, cutting of the cone of this fast Takahashi system. That is obviously not good.
The tilter should have been the same as in the 6200 camera. We need this solution as soon as possible. I for one am stuck with it, and our camera + scope need to travel 2500km to a remote observatory. I really want to test everything here now before shipping it. Please provide us with this tilt adapter! Should not be a big issue I think to provide it in aftersale (or even better: just include it with the camera as it should have been in the first place ;)).

Is there a way you can use the filter drawer and the M68 OAG with the ais6200 mm?
0
0
Yes, you could try the following way: ASI6200(12.5mm) + M54 filter drawer( 20mm) + M68 OAG(17.5mm) + telescope.
Note: If your telescope has M68 threads, it can directly connect with M68 OAG. Otherwise you need to customize an adapter.

Hi,
Can I use an SX Lodestar II guide camera on the OAG with this camera?
Also, could I use a 6mm camera rotator between the FW and Camera without causing vignetting?
Thanks
Jon

Yes, you can use Lodestar II guide camera on the OAG. The vignetting might be caused by shelter, filter hole, interface or large senser.
Could you tell me what 6mm camera rotator looks like? And how to connect with EFW and camera?

Hi, I wonder if the new ASI071MC PRO will have the same housing and 55mm backfocus, so does the 071MC PRO can be combined with in the same way with the ZWO 2″ EFW as well? Thx

The backfocus is depend on your telescope,instead of camera.
Sorry,the 071MC PRO can not be combined with the ZWO 2″ EFW in the same way.

Is there a way to connect a Nikon lens directly to the EFW withe proper backfocus? The available M54 Nikon adapter works great with just the camera, but does not provide proper back focus when used with the EFW. Thanks

Hi. I do not have an OAG, so I’ll just use the configuration ASI6200+tilt adapter+2″EFW+M54-M48 adapter+M48-M48 16.5MM adapter. My problem is that the M54-M48 adapter is loose (it doesn’t have a position where it stops rotating inside the M54 thread of the EWF exit hole) and therefore the 16.5MM adapter and everything that is connected to it (other adapters and coma corrector) is not securely tightened to the EFW. What am I doing wrong ? How can I make everything securely tight ?

Fabrizio, I’m considering purchasing a 6200 and using it without an OAG. Is it correct, from your experience, that the camera + FW will not tighten down?
Thanks!

The EFW and ASI6200 camera are connected by screws which can be tightened.

Couldn’t EFW be used to hold a dark frame filter? Using it that way, what is the best way to attach it?
0
0
Could you tell me what is dark frame filter?
0
0
It is a filter that is completely opaque so you don’t have to go out to a remote observatory and put your lens cap on the telescope to make dark frame exposures for calibrations.

We are sorry that we haven’t used it like this, but you can try it. And you could pay attention to the light leakage during the test.Will you share the result with us if it can be used.Thanks in advanced!

Katherine: yes, but how? 🙂 I have the same question.
We would use the ASI2600MC with the 2″ fw and new OAG, how to connect for backspace 55… Thanks.

You can remove the sensor tilt like ASI6200 and then follow the steps given by this article.

Hi Katherine,
Followed the guidelines on my brand new 2600MC + 2″ FW + M68 OAG, but I run into trouble. I need female M48 scope side, but much to my surprise, ZWO opted to deliver the 2600MC with a M42 tilt plate. So none of the adapters that are explained in the 6200 configuration scheme will work. I am stuck. Impossible to add another adapter as the backspace will be too
long, and frankly M42 for an APS chip, in front of an OAG and a FW will give vignetting on my fast Epsilon 180ED. I know I could get a M42 to Tak adapter, but that will definitely not solve the vigenetting. Why this decision to put such a small peekhole in this nice camera 🙁
Is there a way to urgently get from you a tilt plate that will work on the 2600 so I can use the pieces of the fw? I suspect the holes of the much wider open tilt plate of the 6200 will perfectly do, as mechanically it connects the same way in front of the OAG… This scope/camera setup will be set up remotely, so I need to be able to test this the coming weeks. For now, no way to continue any test, unfortunately.

Hi,
Maybe you could use a M54 Sensor Tilt Plate to attach M68 OAG and M54-M48 adapter to your M48 telescope. There is a link for your reference:https://astronomy-imaging-camera.com/product/m42m54-sensor-tilt-plate

If I may telle something : it will be interesting to put the sensor chip 90° the position you show on your picture. Doing that, it is easier to balance on a newtonian telescope, et and you can do the right orientation for delta and alpha (alpha on the long side of the sensor, delta on the small one.
If I explain badly, don’t hesitate to ask. But your solution is also very cool!

Thanks for your feedback and I will sent your message to our devs.
When you connect the camera to the scope, the orientation of the camera won’t always be fixed as it is shown in the picture.

Can sensor tilt adapter be skipped? it seems like it can cause some vignetting.

It will not and cannot be removed if you do not have other adapter to replace it.
