Awesome pictures. Very clear and beautiful images👌. But loss of your mother on the same day of your capturing above images makes me sad.

This must be the manual of your telescope: https://www.meade.com/pub/media/downloads/53/DS2000_manual.pdf Yours might be DS-2000 series reflector telescope. Surprisingly I have one with the same 114mm aperture and 1000mm focus length. The only difference between yours and mine is the finder scope. I got with red dot finder. And I got the same manual as mentioned in the link above. Here is my telescope in action!

I too had exactly the same problem of lengthy T2 ring. It is too long for my Canon EOS M50 Mark II camera that has EF-M mount. Couldn't get a shorter T ring from local vendors. When I kept the camera without any lens close to the draw tube of telescope, I could use telescope focuser to get sharp focus. I badly needed a shorter T2 ring of width 10mm or less. Then I thought of extending focus of telescope using a Barlow lens that I already had. This is not the best solution but it worked (Now I see that you already considered the Barlow lens!) I could get good focus and take pictures of the Moon using the mirrorless camera. Here are pictures of my telescope with the camera and Barlow lens, and the picture of the Moon:
