Telescopes anyone?

Anyone here use telescopes attached to Pentax camera bodies?

I have a few myself. Everything from "borderline" telescopes; which are actually just preset mirror lenses, then to short length (real) telescopes), all the way to a Meade 20" (bot a Meade Max mount and working on a secondary). The Meade is great and I've used it with two Pentax bodies, but the focal is really too big for non Astronomy dedicated sensors.

I'll be posting some new photographs soon on my trip across the pond to witness the NASA launch today. Interesting to see the numbers of companies (and even agencies) from here in the United Kingdom that are also directly involved in making NASA work!!

I hope it gets launched today.

His Nibs used to work on scientific satellites when we lived in the UK, mostly involving NASA and some European agencies. Good times. We visited some old friends from NASA in October when we were in California.

In answer to your question though, no I don't have a telescope, though it is something I would enjoy if I lived somewhere with some sky and some darkness.
I made my first attempt at astro photography in Death Valley. Astounding to see so many stars, but my photos weren't great and clearly need more practice. I shall try again if we go to La Palma this winter.

Let me also add in...

I have a very old (even unlabeled) adapter for my t-mount telescopes to convert them to PK. Anyone happen to know who makes the best PK to t adapter presently? I've seen quite a variety in the quality of these. Unfortunately I've even heard of a few getting literally stuck onto camera bodies. Ouch

Ah, I see the launch was successful. Lucky you getting to see it.

Pentax make telescopes and binoculars, which we don't often see discussed on PU as these are quite specialised areas. I've often fancied having a good astronomical telescope but I really doubt I'd have the time to use it properly.
Best regards, John

Might be the time to go for it? Link to Express website link

Putting a telescope on a camera is quite an arduous task, they're not ideally suited to photography unless it's deep sky astro work (where you really need a very good guided 'scope, expertly setup). I have a 4.5" 900mm Newtonian reflector with a 20mm (45x magnification) eyepiece which (for eye viewing) is pretty much equal to a Tamron 500mm f/8 mirror lens and 10mm eyepiece adapter (50x magnification). The Tamron is much more compact and portable (a big telescope with tripod in it's box takes up a whole wardrobe).
