Huh weird. It can't focus very close for sure. But does about 10m OK, so doubt it's out of range. I fitted a steel mount now with lens support, so will test next time with my full spectrum a5000 and uvir filter. It's very smooth for actually just moving the camera around while videoing - that's a 315mm ff equiv on there so quite a reach, and with the app I can very smoothly move it around. And of course Sony has its own remote view.

its got a custom white balance set which sorts it out. what I've found kinda weird is that, at least on my mac, the raws are read and processed with that white balance too, which is a bit weird - my 6d's don't do that.

a bunch of the jpgs straight out the camera. my filter goes from 520-720nm. the more colour, the lower I'd have shot. apologies that there seems to be a couple of hairs floating about.. and lastly a few with no filter at all:

sure, which is accurate in that, that is how they are usually described. However it was my title and description the Op had an issue with. hopefully that's cleared up now. 👍

correct. I didn't think it was confusing, but clearly I was mistaken... 🙄

Michael, we both did go to some length to explain this, even though your reply was a bit er..uppity. give us a bit of the benefit of knowing what we are talking about. here is the camera and filter: its the filter I am using at the moment- a 49mm EXTERNAL filter. I can take it off (ooo), and replace it with a UV/IR block, or an L-ultimate, or an Sii 3nm or whatever I want. I have effectively, as Stuart says, made my camera the same (sort of) as an astro camera.

All good info - I'd just add that the remaining filter also cuts UV. Hence when both are removed - you get access to ranges below and above the visible range. Not all cameras have 2 filters either - for example the a5000 I got has only the one - so removing it gets you full spectrum. that's common with quite a lot of more point and shoot cameras. So to shoot nebulas,etc you must ensure you use a regular uv/ir filter with it. Whereas, as Stuart says - with my 6d, I had only the LPF-2 filter removed. So I don't need to use a UV/IR pass to shoot nebula with it.

er no you've misunderstood a bit there. The filters are removed making the cameras sensitive to ir and uv in addition to visible light (FULL SPECTRUM) You then would almost never shoot with them without adding your own filters. Otherwise you will get everything from 300nm up through 1000nm..which does not look great as the uv and ir will be focusing at a different point to the visible light. Here I am shooting with an adjustable IR PASS filter. Hence only various frequencies up from what pics say..720nm being pretty much no visible light. I have a uv pass on order.when I fit that instead, I'll be shooting just UV light. Hope that clears it up.

interesting. and does it work ? I mean you could test during the day on scenery stuff ?

pre=order price was $399 from zwo shipped. at the time that was aboot 300 quid

here's a few more: 530nm out the camera colours - just tweaked for exposure, brightness, contrast: 720nm (made black and white as no colour info by this stage): 560nm - out the camera colours - just tweaked for exposure, brightness, contrast: 720nm again, again, tweaked for exposure, brightness, etc then converted to black and white as no colour info really.

haha. I only peeped because I get the same problem! what I tend to do now if I see it is have a less deconvoluted layer and blend that in for those stars if it's particularly obvious. I've become a pixel peeper! arg!! what have I done!

got camera. pretty cool. here's the back garden with 550nm IR pass and a channel swap.

Good attempt. I think there's some more detail in the highlights that you've clipped out ? easy to do with the bubble.

A nice example of how sometimes you don't need a massive target in the middle of the picture for it still to look very interesting.

very nice funky looking galaxy. I wonder if the aliens in there know what it looks like.

just for kicks - here's what 26 mins with a seestar s50 gets you:

I like that a lot - very nice colours. amazing detail That's FF for you! wow

Nice. I see you are getting some weird artifacts on some stars though ? too much blurx ?

very nice. And a tricky target. Can't see a difference between the two versions myself.

I think folk would still be happy to see saturn like that - you can see the rings. What they do need to do is allow the exposure to be set properly so it doesn't just c;ips things out on planets.

here's 26 mins on the crescent, stacked and processed on mac. note the sort of faint circular rings - I reckon caused by the L-extreme. Not having had time to do a side by side and compare it with 26 mins with internal dual band, this is not I admit, that useful. But the weather was not playing ball. But to get results like this after 26 mins with a bit of kit costing 300 quid is pretty amazing imho.

huh.. so the results of having the canon M100 mounted are.. surprising. surprisingly bad. bare in mind that during this time it was shoot the cresent nebula and stacking all the files fine, so the camera was not affecting the tracking of the S50. However every single frame bar one is like this. And it was set at 70mm equivalent, 20 sec exposures. Now, either the S50 is doing some really fancy optical micro correction on top of the AZ movement, and missing this, results in this. Or, more likely I think - the rubbish plastic arm mount I had it mounted on caused just a tiny amount of constant oscillation. I'll have to try with a different more solid mount to find out which. . here's a typical sub, and close up. so unless I was seeing into a tear in the spacetime continuum where stars have all being replaced by space ducks... we have a vibration problem.

oh I wouldn't buy one for the S50 - I just have them for the 'real' kit. I just wanted to see if 10s exposures would work with it. I'm sure the inbuilt wider dual band if great for the S50. It's really just an 'if you have one already'. I mean, the whole S50 cost me 300 quid. An 2" L-extreme costs 210 quid. don't buy one just for an S50! I also have my canon M100 mounted on it by the way - will see what that looks like in a bit.. clouding up soon, so prob only for 30 mins left. stu

8mins into crescent nebula using L-extreme filter rather than built in dual band. Seems to be working nicely. Stu
