best jupiter in the world :rolleyes:

[ving]

here we go...
taken last night, seeing was really bad (2-3/10)

[ving]

hmm... a bit heavy heanded with the first one :P

[[1ponders]]

Glad to see you're getting out there and making the most of a rapidly disappearing Jupiter ving.

Details man, details. Settings, scope, mount, time, place, were you allowed back in the house after spending all night outside? ;) Details.

[asimov]

No, I like the first one best, it shows more details!:D

Great job Mista!:thumbsup:

Permission to have a go at reprocessing it for ya! :)

[ving]

8" newt f6
lpi plus 2 2x barlows.

pretty standard k3 settings. I noticed that when the pros here take pics the have the exposure set to 1/25th or something... i do that and it disapears of the screen!!! i had to have 1/6" exposure!!! seem awfully long! whats with that?

standard processing as per mikes tute except the first one which i went heavy on teh wavelettes...
thats about it.
oh and fiddled in psp8 with unsharp and other stuff

[ving]

re process away asi :)

[joe_smith]

Good ones Ving They look pretty cool.

[[1ponders]]

something strange there. What are your gain and fps settings? I might get a chance tomorrow night to get the LPI out and check it out. Those onion rings you are getting are normally a sign of the gain not being set high enough.

[Hitchhiker]

Well done, ving.



For my Jupiter images with my LPI (10" SCT & 2.5x Powermate) I use 1/4 to 1/5 of a sec exposure.

I remember Paul posted an article on K3CCDTools not reporting exposure times correctly for the ToUCam (the exposure time reported varied with the fps). I use Envisage for my captures and about 1/4 sec fills the histogram nicely.

[asimov]

Yeah, the good ol' onions come into the picture if you try to reprocess :doh:

Oh well.

[RB]

Goodonya David.

:thumbsup:

[ving]

good to hear. i thought i was going crazy!

[acropolite]

You're getting there Ving, the colours look very natural. :thumbsup:

[[1ponders]]

I've just run a session throough the LPI and there were no Onion Rings but boy the colour sucks. I'll finish processing it and post it later.

Edit:

Here's the image. There are no/very little onion but the colour is woeful. I wasn't able to do anything with the exposure so I just used the default exposure of 50ms and adjusted the ones I could. I will admits that I found it very frustrating trying to get the settings right.

I also did a run using Virtual Dub capture, but I can't find where VD saved it to :P . I'll track it down and post it later

Hi Mr. Ving-a-ling,

Nice to see some of your stuff, and I would say that is quite a reasonable result with the conditions you had. Yep I also like to see the most detail= the first one, colour is good. Can you increase your gain and either decrease brightness or shorten your exposure, to keep the image at the same brightness. Looks like you had the exposure just right in the first one, just gotta kill the onions.

Like I said nice to see your stuff.

[jjjnettie]

I like the first one best, great colour.
Keep em coming.

[beren]

:thumbsup: Good on yer ving

[seeker372011]

yes i think you did well as conditions here-visually were shocking. the image in the eyepiece was bubbling all over the place

[ving]

they all had the same exposure seting. Gain isnt where it should be in k3ccd (ie with the rest of the cammera settings), infact i couldnt find gain at all! I just work on getting a certain image brightness on the screen. :)

[Lester]

Hi Ving,

I don't use that program, perhaps someone that does can inform you on where the gain control is. That will help minimise the onion rings.

[ving]

i think the onionrings are from over waveletting lester :)

[Lester]

Hi Ving,

Yes over waveletting will bring them out more. Bad seeing conditions will also bring them to life. But gain at 75% will help to reduce them (well that is what I used with the Neximage) I have not used a LPI. But I would say that higher the gain setting, the less onions you will get. I have experienced the same with the DFK, so my conclusion is that this is similar for all AVI imaging devices.

[ving]

help!!! where are my gain settings??? :(
:confused:

[[1ponders]]

I couldn't find any ving and ended up using the contrast and brightness in combination to try to bring the histogram at the side up to around 500 - 520

[ving]

what vers of k3 are you using paul?

[[1ponders]]

V3. I'll crank up the laptop and try V1

[ving]

yeah i have v3 too... lpi doesnt really work on v1 :(

[[1ponders]]

????? Mine just did. That's is what I used to do these screen dumps. :shrug:

Any way. I set the LPI up in my 76mm copyscope and took a couple of shots of a shrub up in the corner of the back yard.

[[1ponders]]

I found that using V1 I could adjust the exposure settings that I couldnt touch in V3 :confuse2:

[[1ponders]]

Ok I just checked it wasn't version 1 I was using. I have the desktop icon incorrectly named :P :screwy:

[[1ponders]]

This one is from V1 though and all settings are set on auto. Probably won't work with Jupiter but they will give you something to start with.

Edit: BTW it didn't matter whether I was imaging Jupiter or the backyard, K3 dropped frames. Using 5 fps, 10 fps, 15 fps for 60 sec always ended up at 176 frames.

[ving]

lol, i was wondering how you managed to control exposure thru v1 :P
ya silly!
