guessing a minority here is deeper into AP like going to Namibia, doing mono etc. I will post a few results here of my first going thru the data. I usually do this before finetuning, which will be ...

Never had that with my 3 arts. The zeiss apo 135mm I have as well. More vignetting than the sigma mainly. Optic is very good. Voigtlander I heart only good things about. Never had one. If 110mm is ...
-
There are variations. Like said above I have both, chosen out of many, so no decentering etc. The Nikon cannot match the Sigma Art 135 at all, see also here , the 105 is not good for fullframe. Loo ...

Thanx for that. What to write when cofe break, haha. Progress? A difficult topic maybe since it is tempting. The balance between being drawn and driven, well... This pic for example: "Progress" ...

I remember coming home the first time being in Namibia and starting to get pics out of my data, that was maybe the hardest ride. I found out that this astromodification guy did not consult me ...

looks like some are interested. So what else is there to say? I was there for 17 nights and 2 I just spent visually. I can recommend this to all AP's. I see often AP's looking to the ground when ...

here you can see a typical night we had. Quite warm even before, sunset just past 6 pm seeing can be as good as it gets, except you have like this, a little wind, some chaning air: Seeing was not ...

some especially spouses ask "What else can you do there?" and it get's interesting. What I really like are the e-fatbikes they have since a few years. You might not go very long and far, but with ...
-
Not sure how far this will go, also depends on the interest (questions?). astro fotos are usually not the most interesting stuff, so maybe the other things are better posted here. This year I was ...

Hello, it has been my 4th time now there as pure astro tourist and still I feel the first love feelings when I am under these dark southern skies. Maybe only Attacama is better, since a true desert ...

Yes, some like the above did.

false a few frames as already stated false false really? again, you state the obvious again, thanks for enlightening us do I? how do you know? I have all of these things, so what is your point? yes ...
-
Hm yes, off topic but thanks. I guess most won't do dragonfly science here like me ;)

Hi Andy, interesting, yes. I think I read somewhere they really extended the number of lenses already. 0.2 to 0.8? My apo was optimized by teleskop-austria.at and has a strehl of 99%. Of course no ...
-
to be fair I checked the like 20 subs again of the Nikon and there were a few out of focus when looking close, my fault! So we here in a way were both right and wrong, me more wrong, sorry. I had ...
-
well then there must be something wrong since I get with the original raw about 2,7 px fwhm in PI, which is ok to me
-
no, it was focussed well (enough). the autoguiding shows a little drift, do not know why. stars are elongated a bit, but that is not essential. and with the lens you have bad focus control unless ...
-
sure it has been cropped to size. more resolution always helps. But one reason I got a telescope was sharpness and even more so the control of focus, temperature drift is essential

maybe you need to go to a squirrel forum?
