Here's an anim I did of Jupiter and Europa last Tuesday.

Wow very nice!

[Dennis]

Excellent animation Marc, with an impressive image scale and lovely detail, well done.:):thumbsup:

Cheers

Dennis

Wow, so cool!

Can I ask how long did you take for that?

[h0ughy]

Brilliant, gorgeous

[multiweb]

Thanks a lot guys. :thumbsup:
Still learning to focus.



I'll have to check but a few hours I reckon.

[DarkArts]

That's about as good as the raw footage from the Voyager 2 flyby. :thumbsup:

[RichardJ]

fabuleux! :thumbsup:

Richard.

Wonderful job there Marc, one of the best I've seen. How did you get your GIF so large? Really looks impressive. :thumbsup:

[multiweb]

:lol: Thanks mate. I wish. :thumbsup:


Merci beaucoup. :thumbsup:



I've attached my settings. I upscale 150% as advised by Trevor Barry. Got heaps of good tips from Anthony Wesley as well on what to do and not to do. Top blokes both of them. As a noob just getting started in Planetary imaging their help has been invaluable and saved me a lot of guess work and pain. I wish they were more like them in the astro community willing to share and teach because in the end that's what it's all about, progress as a group and enjoy the hobby to the full :thumbsup:

I try to focus correctly but still guessing most of the time even with stabilize turned on in FireCapture. I find that very challenging most of the time so if anyone has a good trick for it or a repeatable method I'm all ears. :)

Here's what I've done for these.

In AS!3 I try to use multi scale AP. Emil video says it gives a better overlap and results. Trevor sets his manually but his data is far superior. This works for my data for now.

I also found that although AS!3 may say you have only 25% or 40% of frames above the 50% quality it pays to slide the frames and check visually. Often the frames at the tail end still look ok so I stack them. This results in better SNR and the loss of details is not significant if you're careful not to include really dodgy ones. Easier to process and sharpen later in Registax 6.

In Registax 6 I do in order the sharpening, contrast/brightness to set the black point then color balance, rotate and upscale 150% with Mitchell algo.

That ugly double limb on the bright side I mask/feather in PS. You can spend time using the deringing in Registax 6 to do a better job but that's just how much time I was willing to spend on it.

Then in PS you do your colour saturation/cropping, load all layers to an animated GIF 0.2s per frame and that's pretty much it.

An excellent animation Marc, great detail.

[multiweb]

Thanks Jeff. :thumbsup:

[Atmos]

Very nice Marc, great to see it rotating!
What is the gap between frames? 20 minutes?

I second the voyager fly-by remark... this definitely looks like you were right there. Amazing job, mate:thumbsup::thumbsup:

Any of you guys using Sharpcap to capture instead of FireCapture? I just noticed I can get ~140fps in Sharpcap with the native driver opposed to ~50fps in FireCapture with the ASCOM driver for the same gain/exposure settings. Big difference. :eyepop: I think I'm going to can FireCapture and use Sharpcap instead from now on. :shrug:



Thanks Colin. :thumbsup: I captured for 180s then a delays of 3s and do it all over again unless I refocused and there's a meridian flip somewhere in there too so you can see the jump.



:lol: Thanks mate. :thumbsup:

[Peter Ward]

That's very impressive. Good write-up too. :thumbsup::thumbsup:

[multiweb]

Thanks Peter. :thumbsup: Still a work in progress. I figured out my low frame rate for both OSC and mono was linked to the ASCOM driver. The native driver has no issue whatsoever so I should be able to get a much better SNR and finally focus properly. :)

[RichardJ]

Hi Marc,

I use SharpCap Pro. It just works so well with my set up for both Planetary & Deep Sky.

Richard :)

[multiweb]

Thanks for the feedback Richard. How do you like the focus assist tools? Which one do you prefer for planetary?

[RichardJ]

Hi Marc,

I just magnify the image and get best focus by eyesight.
I haven’t explored using the focus assist tools. Maybe I should.

Richard :)

[DavidU]

Mate !!!! excellent gif right there Marc.

[bigjoe]

Superb Marc. 3D ..I love these transits.
Bigjoe.

[multiweb]

Thanks David. :thumbsup:


oh wow, you've got better vision than mine then. :lol: I'm really struggling with focus by eyesight. I see there's a list of assists. Going to try when the bad weather has passed us.


Thanks Joe. :thumbsup: Yeah they're pretty cool. I want to do a lot more of them but when there are shadows and possibly the red spot.

Marc

That’s s fantastic loop!
Amazing detail

Thanks Ben. :thumbsup: Just noticed some of the bands are spinning at a different rate.
