Pentax Q for astrophotography beginner?

The moon detail with Gassendi, Copernicus and Erastothenes craters (most impressive craters - left to right), Montes Riphaeus, Montes Carpatus and Montes Apeninus.
This was made with Bresser-Messier Ar 102 - 102/1000 refractor (1000 mm FL, f 9.8, ISO 400, 1/200 s, 6 frames, only, stacked in Sequator). It seems this is very good match as these are just baby steps with much room for improvement. Moreover both telescope and my Q are white:)

I have the same when the battery in my K-r is not fresh, esp. with lenses having no "A" contacts. The best remedy in my case is to use Eneloops/IKEA Ladda AA's, not BC-109's. Also the new batteries are better in this regard.

Wow - sharp and with nice stars! Is it Super - or SMC Takumar? I have one 5-Element 135/2.5 but was only using it wide open from time to time... Do you remember the f-stop used here?

Very nice! Many say FA 80-320 is not sharp, but it seems to produce nice color which is sometimes even more important. How do you rate it regarding detail preservation?


I would say sharpness/contrast is easy to improve in post when needed, but having nice picture (colour, tone, saturation etc.) with no postprocessing is always a bonus.I have many fine pictures with FA 28-70 even if technically it is not the best lens.

I think that Q/C-mount adapter plus C-mount/1,25" adapter is the most common option.

Thank you! This is really good lens (04B I mean), even if it was not part of "SP" line.

Fresh (brand new) batteries could help. On mine with some older batteries I have no problem with modern lenses or lenses with A-contacts, but with older M-series lenses it happens. M-lenses are close to t-rings as they have no contacts on lens base at all.

SP 23A (60 -300) on K-7. First one closer to the long end, second one around 70 mm.

BTW, I realised that I need one more P-KA mount. To my surprise there are (almost) any Adaptall listings in the marketplace. Maybe one of the Members here has one spare for sale?

Thank you! No, chromatism is almost not visible. I wanted this one (70 mm model) instead of 90 mm one, hoping that even if it will resolve less it will have no abberation at all. It seems to be the case. Celestron Astromaster 70 has f 12.9 but Q seems to doesn't know that it is so far in diffraction zone - photos seems quite OK.

Genuine Q on Celestron Astromaster - 70 (900 mm) - stacked from 3 images, cropped. I'm sure much better results are possible with this setup.

FA 28-70/4 is not the aviation lens usually, but I had today the biggest plane of the world behind my windows, so it turned out OK.

I have no problem at all to focus using standard C/PQ adapter plus C-1,25 in my Newtonian. It is not true for all my other cameras, but for Q it works. I'm just putting the eyepiece cap on the eyepiece adapter when not used.

Not the best photo, but clearly great camera for travel! I used my Q on the go at the airport while running (almost) for a meeting.

Genuine Q plus Tamron 16/1.4 C-mount lens is my favorite combo for short business trips (taken yesterday in Brussels, Belgium).

It is nice lens - maybe not super sharp and contrasty, but I found it usable for nightscapes/starscapes (infinity photos) wide open on APS-C. Seems to be better for this sort of images compared to it's modern incarnations.

I always planned to get M150. And, looking at the photos, you prove it is a good idea. How do you like it?

Now I can rationalize not getting M150 little bit as I have M 75-150, which is nice also, but...
