C or CS mount to M42

Sat May 23, 2020 12:35 am

I am hoping to use my Pi High Quality camera with my telescope. The scope interfaces with M42 threads. Is there a threaded adapter with male threads for the camera mount transitioning to female M42?

Google is broken today?

I have been Googling and can't find it. That is why I asked here.

I don't know what to say... The first search I used got the results for which I posted the link. And my Google-fu is pretty poor. If I had to find a lens adapter I could probably do it without Google just by looking on one of the major NYC photo suppliers, like B&H.

Are you sure it's really a M42 mount instead of a T-mount? Both are 42mm in diameter but the thread pitch is different. T-mount is commonly used in telescope and microscope attachments.

I have SRB one, works good.

But as noted above, check if your telescope is M42 or T-mount, they have the same diameter but different pitch angles and are often confused. Most telescopes actually use T-mount. Here is example of T to C adapter: https://www.astroshop.eu/extension-ring ... le/p,22010
Those should be available in every astronomy shop.

Thank you for the examples and help. Most of my search results yielded the wrong gender(s). I am using a t-adapter. I ordered a part. I was too slow on the uptake to get my order in for the high quality camera on the announcement day and am still waiting. It will be a race between the camera and the adapter.

This is an adapter for T2 thread used in the telescope area (which is 42 mm but with 0.75 mm thread pitch, instead of M42 with 1 mm thread pitch): https://www.astromarket.org/andere-adap ... r_0_select

I ordered the part from Astroshop (Germany) Saturday morning, and it just arrived.
