Jupiter 14may

[Lester]

Thanks David, if you like it ,it must be good. Hey mate I am loading your AVI of jupiter it will take 1.5 hours= we haven't got broadband.


Paul, No I didn't use histogram in registax this time, I have in the past. I must have been in toooo much of a hurry. Might give it a try and see what comes of it.

Sorry this should have been 2 seperate replies.

Hi everyone,

Here is another one.

OMG

you can really see the resolving power of the 14in coming into play here - check the detail... fantastic stuff Lester

[Lester]

Thanks Robert,

I think it was just a matter of being at the scope at the right time during good seeing conditions.

Plus the help of Asi in the processing side.

[iceman (Mike)]

Wow, I would really love to have a go at that avi!

Top stuff Lester.

[davidpretorius]

that is excellent.....hmmmmmm 14", i want one.

[Dennis]

Wow - now that is very nice indeed; huge image scale but not at the expense of detail. My, my, what a difference 14" of glass makes.

Great job in capturing a cracker of an image, and Asi for processing it.

Cheers

Dennis

Hi-ho Lester. A reprocess of your second image posted in this thread I did lunch time yesterday...RGB split & LR deconvolution & all that jazz.

Pity about the edges of Joop. Wouldn't mind having a crack at stacking this data next time I'm out at your place...or at mine for that matter.

[Lester]

Thanks everyone, for your comments.

Yes the conditions were good (as good as I have seen in 2 months, since I started imaging Jupiter)

One thing I am going to try to see if there is any improvement is not use the Heated dew stopper and have a fan on a pedestal blowing ambient air over the corrector. Many years ago when using the Celestron 8" all I used to prevent dew was just that. Seems to me the Ice packs around the tube are fighting against the heated dew stopper. Last night when humidity was high the ice packs were not bringing the scope temp down to any more than 1 degree above ambient.

On the 14 may when I took this shot the tube was the same as ambient. And as the seeing deteriated the tube temp climbed above ambient by 1 degree. So its critical to keep scope at ambient. I know you chaps know this already, but it may help someone else who reads this.

Just another reproduction of Jupiter. Managed to limit the stack in Registax to 200, still got a long way to go in Picture Publisher and Photo Shop.

This image was processed in both Picture Publisher and Photo Shop.

Very nice Lester, very good processing work.

This is the 2nd Avi from that night.

Stacked 170 images=manually done, just started from start of list after alignment and discarded the bad ones, until I reached 170.
