At the bottom of the screen you'll see a section marked "Additional Options", the second box "Attach files" click the "Manage attachments" and a Pop up menu will allow you to upload image images. Note the image size limits.

Thanks for that.

The male thread fits the COAG female thread, but the female thread of the adapter does not fit over the Adapter plate's male thread.

(There's a 3.25" thread hidden underneath the rear cell thread of the Meade. Used by things like Peterson's Eye Opener attachment https://optcorp.com/products/peterso...acf-telescopes) |
Yep, agreed. That's where the .7 reducer or the adapter plate thread to. From the reducer, you connect the adapter plate as those threads are the same. However, from the adapter plate onwards, the threads are smaller, but no quite 48mm.

It sounds like your COAG has a female SCT thread(?) why not directly attach that to the rear cell? I assume it's one of these, do you have all the attachments?? https://www.bintel.com.au/product/ce...v=322b26af01d5
You may be looking at the front of the nosepiece...this has a 48mm filter thread, for 2" astronomical filters. |
Yep, I think you hit the nail on the head. This is a piece to use with 2"screw in filters before your eyepieces. At least that's how I see it.
