Anyone else had a slug get into reflector?
yelsac replied to yelsac's topic in Discussions - Scopes / Whole setups
Yes I've done it once before, just a lot of bother as I've just bought a new camera for imaging Jupiter. Might try & leave it for a few weeks hopefully it won't do to much to the coatings. Happy days 👍 Unless anyone else suggests it will damage it sooner 🥴 -

Oh the cap is left on, the blighter somehow sneaked in between the mirror & base of the reflecter where the collimating screws are, stupid creature 🫣 -

Do you think that will damage the mirror surface? -

Interesting so the fact it's organic does that cause more of a problem? -

Yes I think it did, I found 4 dead very small slugs where I store my scope. hadn't noticed them before. Thanks I'll have a look -
A bit late to the party. First light with new camera QHY5III 462c. Seeing was awful windy, misty, strong jetstream etc..... but just had to have a go at the double transit. Trying to get used to the new setup, but even though it wasn't idea conditions I could still see the improvements over the old QHY5LIIc. I'm excited about what could be possible on one of those clear nights if we ever get one! setup- 10" f4.8 reflector, QHY5III 462c, UV/IR cut, 2.5 Rev barlow, 120 sec avi, pipp, as3, image analyzer. A few all a little on the noisy side I'm afraid

Great So am I right in saying, when I open the stacked image & enter the date/time & my long/lat then save, is that it? Or do I have to do more?
-
Quick question Neil I've got a 6min Avi which I'm trying to put through winjupos. I've put it through pipp & quality which has reduced it a bit. Then in WJ I've selected the de-rotate of video, entered the start & end time but no idea how to get the image measurement of the Avi, do you have to stack it first to get an image?
-
Really nice detail on that, I've recently purchased the QHY 462C so I apologize in advance for the dreadful cloudy nights coming! It's all my fault 🫣
-
Excellent, what camera are you using?
-
Hi Eris Appreciate you having a go, it does look a little less noisy than mine 👍
-
Interesting so which is better de-rotating an image or a video?
-
Must have a go at winjupos, next session I'll try a 6min vid 👍
-
Thanks for your reply Alan Yes my exposure is at 5ms but the maximum FPS is around 68, I can get it up to 120fps if the video size is 320x240 but that's too small for me to capture. Appreciate your other thoughts 👍
-
Woooow a lot more! Do you use this IR890 CH4 filter that you can get with the 462C?
-
Thanks for having a go Neil really appreciate it 👍 I know it sounds obvious but I'm wondering if getting a more sensitive camera with a much higher frame rate is what I need. With my QHY5L-llc I take roughly 9k frames per avi at around 67fps at 640x480. Then cut that down with quality estimation to around 6K in pipp. Depending on the quality graph in AS3 I tend to take the percentage about 50% which normally is around 30-40% leaving me with around 1500 to 2000 frames that actually get stacked. Do you mind me asking with Jupiter what Video size & fps you get with the 462C? Also what percentage roughly (I know it depends on seeing etc..) you stack in AS3?
-
Yes there's a little, still really frustrating though. Can't tell if the focus isn't quite there or if it's just ME! with my processing 🤔😁. Also I'm not sure if the scope is correctly aligned. I've bought a laser collimator which I've tested to make sure it itself is collimated but after using it & when I do a star test it looks slightly out! I think I could do with upgrading to get a more sensitive camera to. I know this is a real cheek but...... Could I ask Neil if you''ve got a moment or two would you mind having a quick go at processing the same image to see what you think? I've uploaded the original & the drizzled version. original.tif Drizzle15.tif

Love the detail on both 👍

250p scope, QHY5L-IIc, 2mins avi at around 65 fps, Pipp 9k frames down to 6k, best 40% from Autostakkert, probably over did it with the wavelets in registax then a fiddle in Image Analyzer. Still trying to get the balance between detail/noise! I find the image is extremely noisy but didn't want to loose the detail I had 🙄. Its also 1.5 Drizzle & upside down 😂 Any thoughts advice welcomed & appreciated
-
Love the detail you're able to get, very envious. Looks great 👍
-
Awesome as usual 👍
-
Thanks for your reply Craig. Wiener deconvolution, that's an interesting name, what is the purpose of that? Does it sharpen/blur? I haven't used Astrosurface, but I'll certainly have a look. Clear skies (one day/night 🤦)

Jupiter 20/09 with 250p, QHY5L-IIc, x2.5 Barlow, NEQ6. Seeing wasn't great & although the majority of vids were awful had a couple of avi's where the seeing improved a little. Process- Pipp, Autostakket, Registax 6, Image Analyzer. Still struggling with getting the processing right, can't seem to get to "the natural look". Although its better than previous attempts, I find it hard to keep any sharpness/detail & not have it look over processed. Its trying to get the balance with not overcooking the wavelets in registax but still bringing out detail & having it look smooth. I found that using the AI Denoising in Image Analyzer sharpens the image a little kinder than the wavelets in registax. Any thoughts or advice would be much appreciated
