Good starting point for all things stellar: https://in-the-sky.org/

GillE:
It's a Celestron Astro-master 130 telescope.  I have a T adapter which means any Nikon DSLR can be connected directly.  I'd prefer to use my full-frame D850 but I fear it may be too heavy, in which case I'd resort to my cropped sensor D3300.  Insofar as aperture is concerned, the camera connects to the telescope via the lens mount which means I cannot use a camera lens.  Therefore, there's no aperture.  If I were to photograph the night sky without the telescope I could mount the D850 onto a tripod and use a Sigma 150-600mm sports lens with a F5.6 aperture or possibly a lens with a shorter focal length and a faster aperture.  I have a variety of ND filters, for 1 stop up to 10 stops.

Thanks for the link to in-the-sky which looks very informative  :).

I had meant the aperture of the telescope.

Looks likely that the counterweight on that telescope wouldn't cope with the full-frame TBH. You will likely get similar magnification with your  typical lenses. I'd do that for the moon, with some form of ND filter.

The benefit of a correctly setup telescope is that you should be able to use the RA wheel to track the object.

Oh I meant to post before:

Thanks Sam  :) .

GillE:
Well, I had a go at tonight's 'Wolf Moon'.



F2.8, ISO 800, 1/3200 sec, focal length 200mm.

I'd like to get more detail but perhaps my gear isn't sufficiently sophisticated.
