Celestron T-mount and adapter to attach a Pentax Q camera body on a standard 1.25 inch telescope fitting. I have been using this "straight through" on a Nexstar 4SE with excellent results (see images) but this a widely used telescope fitting so it will fit others too. The Pentax Q cameras have three advantages for this purpose (1) they are tiny and light (2) a relatively small sensor size so the image fits and (3) you can use a remote electronic shutter release avoiding problems with vibration. NB camera shown is NOT for sale. Moon images are genuine shots with this setup. Not 'stacked' images. On one of them I marked a red square with the Apollo 11 landing site. Postage included.
