Yeah I think once you own a 135 the corners become a lot more interesting 🧐 I still use my 533mc but I’m dying to try a 2600mc
that looks great
Youre in a sweet spot there with that camera since its square sensor doesnt ask so much of the lens (a mono 533 would be interesting). Once you go bigger you need a microfocuser to tease out the corners (a b-mask only gets you close).

I haven't even looked at the main subject yet.. its the corners I'm awarding the "likes" for 😮
Thats why I brought it its all about the corners (first place I go on an image)

Well, not a lot on last night, clear sky, but moon in an unfortunate spot so I swung around to this one for a couple of hours.
The primary goal of the image was to perfect the corners at full speed over a 22mm diagonal. And, Ive pretty much achieved that.... not bad for a 450 quid lens
The focus drifted a little as the temperature dropped, but not too bothered about that since its still basically a tester.

very nice. is that with the asi ? I shot the same target/comp basically last night with my 6d +135. Not looked at subs yet but no way as good as that.
Old skool CCD mate QSI583 - KAF8300 sensor. Had to limit my exposure length to 7.5min due to where it was (I have a very limited window on it), at least that way I could generate a stack just big enough to average out some of the noise.

Was this with a dslr or dedicated? Thanks

Save it off as a 16bit TIFF, you might get more responses

Bad LP, but a very good sky tonight. Could probably process it better, but not bad considering the time spent.

Give me an autoguided HEQ5, an APSc CMOS camera and a Samyang 135 lens and I could die a happy man.
Make that x3 sammys, now that would be nice (hoping to get my second in April... all part of the plan)

One for the pixel peepers!
Extreme corner crops from the Jelly/Monkey image... not bad, can be better I think. Getting the focus nailed at f2 is a little tricky in Ha, at least I have the option to lock it now.

There are some absolutely stunning images on this thread. A question for the mono camera users - with the lens being f2, are you using regular (for want of a better word) filters or do you use filters for high speed systems?
Regular filters will do. But as mentioned above, the thickness of the filter is a factor becuase it can have a massive effect of the amount of refocusing you have to do between filter changes.
Personally, I stick with 2mm as more manufacturers use that thickness.

I'll kick it off, a quiet year in astro terms - but things didnt really start improving until towards the end of the year.

Had a couple of good nights now, so Ive been able to gather 4 hours on this at F2.
Corners, pretty good for this speed. Needs more exposure (as usual) if I want to get the noise down further, though my location isnt optimal. Id say the gear is settled enough to take on the road now, but it needs a bit of planning and motivation etc...

What's the capture details for that one please Uranium?
12x900 @f2.8 👍
It's very tenuous though, I'd say about as difficult as the IFN in terms of processing

Quite difficult, I knew there was Ha in the Hyades.... so decided to go looking for it.
Needs more exposure and better processing (when I have the right amount of data!).

Excellent images, what camera have you used for your imaging with the 130pds please?
For that image (and most of my other stuff), the camera used was the Atik 383L+

A quick seardh of google has rumours of maybe april/may before they announce a mono version.
