Saturn 3rd. Jan.

[asimov]

Hi again.

Shot this at 15 FPS..my 1st semi-ok AVI at this frame rate. Seeing was pretty good 7/10. 1/25th sec with 90% gain to try to solve the 'onion ring' problem.

Fair bit of grain in this shot. The colour sUx a bit too.:whistle:

6" refractor & Toucam.

I have more AVIs to process yet so I'll prolly keep adding more pics to this thread.

[h0ughy]

Just a question, is it out of focus or is that the result of the avi's stacked and the seeing?

[iceman]

High gain (in combination with bad seeing) has caused that look. My images with high gain have this "blurred" look, too.

It's a fine balance between gain and exposure and seeing and ...

nice job asi!

[h0ughy]

THanks Mike, I thought that if the atmosphere was a bit dodgy even though it was focused that the image moved making it that way. Not being into this part of astronomy I don't appreciate the efforts made to get the images gathered by Asimov, yourself and RR at times. Too many good images.

[asimov]

I did play with the settings quite a bit with the gain I had. The focus was smack on...I can only liken the out of focus 'effect' to a slight blue overlay for want of a better term. It seems to become more apparent at 15 FPS too..Next time I'll slowly back the gain off until the onion ring effect takes place in the AVI, then I'll kind of know where I'm situated.

Sounds like I should be aiming for roughly 65-75% gain at a guess....it depends on the night though (seeing/trans. etc etc!) It's going to take a long time before it becomes an automatic thing to be able to get the settings spot on for each given night.

Thanks.

with mars it seemed too easy and with jupiter i assume it will be the same, but these "saturn settings" are a real art!!!

can't wait to compare some later.

by the way, i have drilled some holes in a square piece of polystyrene and then rubber banded that to my left focusser. when i am close to focus, i put a chop stick in the holes and fine focus from there.

no pretty but it is working..... i think..... the jet stream is not helping!!!

[iceman]

asi, I found with mine that by adjusting the levels (specifically, the blue channel) you can reduce the blue flaring as a result of the high gain.

See attached:

[davidpretorius]

where do adjust levels ice?

[ving]

zmust be settings, asi said the seeing was 7/10 which i dream about :P

nice one tho asi :)

[asimov]

I'm adding another one I just finished. I don't know where this one came from! I had a quick review of the AVI & thought it was worthy of deletion but decided to run it thru at the last minute. Possibly my 2nd. best to date. Shame about the slight grain in the centre of the globe. I'm going to "hand stack" that AVI 'cos I know from experience I can improve on this by 50% at least! (auto stacking in registax sUx)

That reprocess looks heaps better Mike! TY for that.

Dave, were having chinese tonight actually....pop on over with those chop-stix mate!!

TY ving.

Setting for this image: Same as the 1st one above except @ 10 FPS..

[davidpretorius]

50% better than that, your on!!

that is one fantastic image mate!!

well done.

how to make a fledgling saturn imager cry!!!

i really hate hand picking!!!!

[davidpretorius]

only 30 behind you mate!!!

i catch up when you sleep and you get ahead when i sleep!

[asimov]

"only 30 behind you mate!!!

i catch up when you sleep and you get ahead when i sleep!"
Yeah I know LOL!

This is no lie when I tell you I have both my hands strapped up. I have bad RSI from hand stacking several 5000 framers just before Xmas!!! Now I sit there with a pencil hitting keys that way, can't use my fingers hardly at all but well enough to hold a pencil. I can still use a mouse just.

[ving]

NP mate :)

post me some chinese too :P

[asimov]

Oh I love someone that throws down the gauntlet!! :) I dunno about 50% better but I'll squeeze out what I can though!

Don't worry Dave, you'll get your perfect night on Saturn SOON mate! ;) BTW you have stakes in my images....if It was'nt for your/my laptop none of this would be possible! :wink2:

[mick pinner]

certainly worth the effort Asi, for someone on a learning curve that's a great image.

[asimov]

Here you are Davo.....You win! it's not 50% better! I ended up stitching 5 AVIs together & wacking it thru registax. I started to hand stack but my pencil wore down so I auto stacked. (Cut quite a few bad frames out though)

I've found bink & smack..DERRR! won't stitch big AVIs...had to use virtual dub instead.

I think this one is better to a degree: more detail/better CD/less noise. On the down side the colours leave a bit to be desired/slightly burnt out centre.

[asimov]

Your now 45 behind Davo!:P

[asimov]

Lucky last from this set of AVIs. It's ok I guess.

[rumples riot]

I like the third one John, nice colour, but seeing and focus is a little problematic. Keep em coming dude. Wish this weather was better here.

[asimov]

Thanks Paul. Yeah, the seeing has been up & down like a yoyo!....But mainly down. Last night/this morning was weird....crap seeing with good trans for the 1st half of the night. Mars looked excellent on the laptop, apart from jiggling around all over the joint from the seeing.

[Robert_T]

Hey Asi - I reckon this one is the pick, very nice and worth the extra effort, I like the colours too.

cheers,

[asimov]

Yes Rob, I think it's the best one by far out of the ones I posted. In hind-sight I should have grouped all the images together in one post rather than spread out like I've done, makes it difficult to read..
