Are we sick of Jupiter yet? ....No way!

[[1ponders]]

Friday night, first real Jupiter night out in a month. GRS or no GRS, Jet stream or no jetstream, I was going out before I went stir crazy. Glad I did

This is the first one I've processed. Random pick of about 30 avies. Straight through registax. I thought I'd better give it a shot at an LR Decon in Astra Image. Not sure yet which one I prefer.

8" meade SCT, full saturation, medium on everything else, 10 fps, 1/25 exp, best 500/1200

Image 1 just a light touch of wavelets, rgb shift and curves
Image 2 heavy wavelets, rgb shift and curves
Image 3 Light wavelets, rgb shift, LR 1.2 X 3, curves

Thats the spirit Paul,

I like the centre one. Keep em comming.

Notices the dreaded onions, sometimes you cannot killem. Did you have gain above 50%. With my neximage I have gain at 75% in bad conditions and usually it kills the onions but not always.

Good luck.

I've tried keeping the gain up, but then I have the problem of getting the center burnt out. I'm going to see how they go by bmping rgb avies, aligning them in ImagesPlus and then stacking the aligned bmps and see if that helps.

holy #*%@ batman, where the HELL did this come from.
:eyepop:
What gob-smackingly fantastic shot! How on earth did you pull that on Friday night:shrug: mind you bloody-well deserved after all the hard yards you've been putting in.

The detail's great by any standard, but for an 8 icnh and jetstream over head nothing should of absoloutely incredible :thumbsup:

pat on the back for this one:D

[asimov]

Nice shots. Why is the centre image bigger...a resample in registax or bigger image scale at the scope?

[matt]

Nice work Paul.

I'm with you. How could you possible be sick of the big "Jovial" fella when he's such an exciting and worthwhile target.

Out of the 3 I think I like heavier wavelets version.

Shame about those onions though. I'm having the same struggle at the moment. I'll probably up the gain, but don't like it coz of the potential to introduce grain.

I never tire of jupiter though. Great target for practicing capture and process technique:thumbsup:

Thanks Rob, it was quite a surprise when I ran it through registax let me tell you. The avi looked promising but it exceeded expectations.

Asi the images are the same size, it the thumbnails that look different because of a different crop size.

[Robert_T]

recently I'vehad success pushing the gain up without burnout simply by shortening the exposure time - e.g using 1/33rdasec instead of 1/20th. Obvious I guess, but I was a little slow on the uptake...

[Lester]

Hi Paul,

When I have Gain up, I stop the burn-out by increasing the exposure speed and reducing brightness.

[[1ponders]]

I'll give it a go Rob, I would really love to be able to deal with them. Was that using the 900 or the 840?

[asimov]

As Robert said, yep. Sometimes the transparency won't let you do this all the time though.

[matt]

Rob

Where do you have the gain set (%) when you're working at 1/33 second?

[iceman]

Great Paul, nice to see another planetary shot from you!

[Striker]

Their great Paul...I like the 3rd one the most but number 2 comes a very close second.

Nice to see you get some imaging going...its feal's like months since your last session.

[[1ponders]]

It is Tony. My last real session was on the 16/5, a month ago. There has been lots going on that has been demanding my time. I'm looking forward to having a month or so to myself with plenty of imaging happening.

[Robert_T]

Paul, the settings I've been using are on the 900nc, but expect the same as for 840.

Matt, when running 1/33rd I have the gain up between 70 and 85%

cheers,

Another one I'm happy with except for the damn onion rings.

Straight forward processing as per the last one and a 150% mitchell enlargement

[Robert_T]

Pail, one other thing that may help with the onioning is to stack less frames. Try just stacking the best 150 and see what you get. It will introduce a little more grain (not overly so) and you may find some of your onions fading. You might need to pull back a bit on the wavelets with only this many frames.

cheers,

[[1ponders]]

That has definately helped Rob though I still need to work out how to deal with the blue ring. I'm pretty sure though it's a collimation issue or an achromatic issue with the lens or barlow I'm using.

[acropolite]

Inspiring work Paul, shows what an underrated OTA the 8 inch meade is.:thumbsup:

[[1ponders]]

You're not wrong Phil. I'm still pushing through them to sort out the best of the lot, but I reacon by the time I'm finished there might be a few who couldn't see their way to a 9.25" or 10" sct, look at the 8" differently. I'm very happy at how it performed last thursday night, given the conditions.

[Robert_T]

very Nice Paul, still looks pretty smooth too even with so few frames:thumbsup:

[davidpretorius]

these are bloody awesome!

[iceman]

Great work Paul, that last one is fabulous.

Can you upload the avi of that?

[[1ponders]]

Sure will Mike. I'm hoping to finish working through the rest today. Once I've worked out the best one I'll work out how to upload :D.

well done paul :)

now go and do neptune :P
