Jupiter 15th Feb from tassie - blessed

[davidpretorius]

9:30pm onwards, still and clear, star test, 6 stars in the trap as clear as they have ever been.

got up at 5am, whacked the 25mm in the 5x powermate = 250x and lovely, the 12.5mm =500x, bands look great, 6.5mm in the the 5xpowermate = 1000x and detail still there.

best night ever, i was able to focus on the moons and then was able to watch detail down to the white circles in the bands on the screen.

so 9/10 seeing, videos in std 840k mode @ 5fps, optimized raw mode @ 5fps and 2 x color raw mode at 5fps.

I know it wil be the best as where i normally start with my medium wavelets, the soft wavelets reveal the same amount of detail as the medium has on my previous best.

Then during the 4th avi, it start to dim and i look up and western 1/2 of the sky is full of clouds. Probably for the best, otherwise i would not have gone inside!!!

Here are some samplers. Standard run through registax and then the no wavelets, soft, med, hard

Firstly: std 840k @ 5fps:

optimized raw @ 5fps:

[davidpretorius]

well the upload system seems to have crashed, so I will chuck these in later.

now on to the involved processing...............

[matt]

Great stuff Davo

Hope this isn't too basic a question but which wavelets sliders do you regard as "soft"????

[davidpretorius]

sorry, i have wavelet settings saved so that i can load em up.

[matt]

So, from that, I'm assuming you don't touch the top two sliders??? (left to right being top to bottom in wavelets?)

[davidpretorius]

correct, i use # 3 slider to 5.8 in the create reference stage and it stays there, the 4,5,6 then have a exponental feel about them.

No rhyme or reason, rumples originally showed me 6 the most, then 5 less nad the 4 less etc.

some people may want to have it staggered.

I simply want to get it to a slightly under processed stage for astra image. so "soft" in the todays pics and medium in that wavelet comparisons would be the ones i process further. They just show the detail and i can enhance that detail. Wavelets if pushed too far will introduce artifacts into the image which i do not want.

[matt]

So you actually perform a very small wavelet (#3) processing on your reference frame before fully processing in Registax?

That's interesting, if I'm understanding what you're saying.

Thanks Dave. It's a real challenge to work out a step-by-step process.

[Robert_T]

Wow DP how long will this dream run last... another stunner which no doubt you'll be making even more stunning over the next day or so:)

showers AGAIN here and looks like most the rest of the week :mad2:

[davidpretorius]

registax will sort out the best frames in the initial "align" and resorts them, if you then go to the new #1 frame via framelist and do the alignment again, then the reference becomes the best frame. if you then create a reference with the best 10%, then this becomes the reference for the optimising. a small amount of wavelets ie 5.8 on #3 enhances this reference frame, but not too much otherwise when optimising, the all the other frames will have a hard matching an overprcess reference.

[Astroman]

WOW these are a great set Dave, well done, thanks for the minor tut on processing too, maybe try 10fps to get more frames or does the image look fainter?

looks like your clear nights are over for a few days :( another front heading our way from WA.

[iceman]

Another great job DP - you've had the great luck recently with clear nights AND good seeing! Congrats!

Heaps of detail again, but you just missed the GRS around the corner by the looks of it :)

[davidpretorius]

10fps when the seeing is this good with a toucam would compress the data and i would lose some of it. when the seeing is 5/10 instead of 9/10, then 10 or 15 fps is the go to get a bigger batch to choose from.

yes ice 5am is the best time at the moment temps have stabilized, jup nice and high and beig blessed with a loveley hole in the jetstream.

it really makes it worthwhile when you load it into registax, the "best" frame is sorted to the top and you sit back and look at a single frame that would count in your top 10 inc the processed ones

[matt]

Sorry to hit you up with another question Davo, but how do you then

"create a reference with the best 10%...."????

How do you get the best 10%? Is that by setting your quality filter at 90%???

[iceman]

The "Create Reference Frame" button has a "number of frames" entry next to it. It defaults to 50. I think DP is talking about that.

I leave it at 50, no matter how many frames I stack.

[matt]

Thanks Mike and DP

yes matt, once you have aligned twice, and then limited your frames to say 90% odd , then the optimise page comes up. talking to bird in novembers camp, he suggested you pick the 10% best frames to create a reference. it defaults to 50, but i wil change to 100 for 1000 total frames of 27 for 270 frames

[bird]

Another great image DP, nothing but cloud here again last night...

Just a word of caution about registax and wavelet settings... the effect of the sliders is based on the number of frames you've stacked, so any particular slider will have less effect as you stack more frames.

I've noticed this effect in practise when I stack a few hundred frames the sliders have a large effect, but when I stack a few thousand frames (saturn or the moon) then the sliders have a lesser effect and I have to crank them over more to get the same change.

So just be a little careful with recipes involving the sliders, I suspect that it's not quite so straightforward.

regards, Bird

[davidpretorius]

spot on!

seeing, # of frames, different scopes, differerent cameras, different capture modes

a "guide only", practise and tweaking the setting will get produce your own recipe book , so that given a certain "seeing" night, you can choose the broad settings and save time.

[ving]

you are indeed a master dave, and the moon is quite round too :D

[matt]

Absolutely Dave.

The questions asked in the interest of a general guide. The answers certainly not taken as 100 percent difinitive and set in concrete.

Thanks for your input Bird:)
