That's how I had it setup (new observatory box coming online soon...):

😉

Example or what others are capable of capturing with the OpenAstroTracker and this lens.

And here's a video of it

Almost there with my OpenAstroTracker setup.

ok thanks, but where is your focus mark? As in, when you've achieved focus, where is the mark on the lens?

For those of you using an OSC camera on this lens, where is your focus mark on the lens scale?

Will test that once it's up and running and adjust accordingly. Thanks for the heads-up.

The two main brackets holding the lenses are solid pieces. So they are correctly aligned to each other.

A few pictures of my twin lens system, still a build in progress... but almost there... (waiting for the 2" filter holder to be able to add the second camera and final bracket) If you're interested in the build https://discord.com/channels/693401540744183859/1016760448764350474

Looks like a nice compact setup, I would definitely tidy the wires...

I have received the second lens for my twin system... (thanks @odyseus10)

There is nothing to panic about, just a small batch got some banding issues. Text from PlayerOne: Recently we received feedback from 3 customers, the issue behavior is some horizontal bandings on the top of the image. After we repeat this issue, we notice that one batch of Uranus-C camera has possibility of this hardware issue. (This batch start from Sep. 1st 2022, end at Oct. 25th 2022) Here is the settings for checking your Uranus-C camera: Cover the camera to take dark frame, full resolution, Exposure time: 20ms , Gain: 600, offset: 10 Cover the camera to take dark frame, Resolution: 1280*1024, Exposure time: 20ms , Gain: 600, offset: 150 But there's the coolest thing about it: We will send you the replacement camera once upon we got the tracking number from you. We will also refund you the shipping cost based on your receipt ; ) Please let us know how much it cost you for the import tax when you receive the replacement camera, we will refund you the money, the same way as the shipping cost ; ) so yeah, no stress, no panic, poops happens and Player One have taken care of the issue. They are truly a great company to deal with. I'll spare you the details of the issues I had with the useless UK courier companies... while Player One sorted out the return label within hours of me asking them for help.

So due to some hardware fault on my two Player One cameras, they've gone back to them to be exchanged. I have also recently secured a second Samyang 135mm lens for my twin imaging train. Should be there by this week-end...

The cameras have arrived, they are so tiny !!! Quick mock up with one to see how it looks like on the lens. I'm very please with the overall build quality of the Player-one camera.

Going to use this https://www.astroshop.eu/filter-wheels-filter-sliders/ts-optics-m48-filter-holder-for-mounted-2-filters/p,63651

The ZWO OAG fits nicely, untested as my Player-one Uranus-c hasn't arrived yet (next week).

exactly this ^

Has anyone ever used an OAG on this lens? "lens + oag + filter drawer + camera", the TS Optics OAG is only 9mm thick so it could 'work' in theory.

Let the fun begins...

I think you meant to write: Thanks Phillyo

yes I've been reading about the distance between the filter and sensor, a 1,25" would introduce vignetting if it's not super close. And mono is probably the way to go...

If one was to buy an APS_C size mono camera for this lens (asking for friend there... 😉), what sort of filters would I be looking for?. In terms of brand/quality and size please.

I moved away from my idea of an Askar FMA135 and bought today a Samyang 135mm F2 after seeing so many nice pictures taken with this lens.
