Jupiter and 21 frame animation – Brisbane 17th April 2018

[Dennis]

Managed to grab a clear night where the seeing started off around 4-5/10 but then went to 3-4/10 just as the GRS rounded the corner!:(

This is the 1st frame (00:06 am) with an animation up to around 01:51 am when the seeing fell off a cliff.

Equipment details:

Takahashi Mewlon 210 F11.5
TeleVue 2” PowerMate x2.0
Effective FL=4830mm
ZWO ASI 120MM-S, SX USB FW
RGB, 30 secs each. Seeing (Pickering) 4-5/10
Jupiter Altitude = 68 degrees.


Just before slewing to Jupiter (E of the Meridian), using the same configuration, I looked at the on-screen image of Spica (alt=72 deg, W of the Meridian) and compared it to the “seeing” animations on Damian Peach’s website “The Pickering Scale”:

http://www.damianpeach.com/pickering.htm

Through the Lum filter, Spica’s in-focus appearance looked like the “Pickering 4 rating – Poor” animation.

When I then selected the IR642 Filter, Spica looked more like the “Pickering 5 rating – Fair” animation where I was able to occasionally glimpse partial arcs of the 1st diffraction ring.

Capture Details:
Red

Frames captured=858
FPS=28
Shutter=35.00ms
Gain=50 (50%)

Green

Frames captured=858
FPS=28
Shutter=35.00ms
Gain=50 (50%)
Blue

Frames captured=751
FPS=25
Shutter=40.00ms
Gain=55 (55%)


AutoStakkert!2 was used to Align and Stack 50% of the Frames from each Channel.
Registax6 was used for Wavelets Sharpening.
CCDStack V2 was used to Align/Combine RGB Frames.
PS CC was used to finish off and add text.

Here is a link to the animation on PVOL (http://pvol2.ehu.eus/pvolimages/jupiter/j2018-04-16_14-06-19_rgb_dsimmons.gif).

wow so beautiful, what an excellent rendition

[batema]

That looks fantastic. Well done.

[RickS]

Cool stuff, Dennis!

[blinky]

Well done! Especially in average conditions. Big effort pulling all that together:thumbsup:

[Troy]

Really good images Dennis and looks like some consistent seeing conditions for the animation. :thumbsup:

[Dennis]

Thanks for looking folks, I appreciate your comments.:)

As Jupiter cleared the trees I took a few test AVIs and noticed Europa popping out from behind the Jovian disc.:) The 2nd file is an animated GIF of the event.

Much later, I also managed to record the GRS but by this time the seeing had dropped to between 3 and 4 so the detail is somewhat washed out.:(

I have been very impressed with how these ZWO ASI cameras allow the user to continue capturing planetary images in poor seeing conditions.:thumbsup:

Lovely work, Dennis. I'll have to give planetary a go one of these days. Looks like a completely new set of challenges :)

[Stonius]

I love planetary animations! Nice one! :-)

So was that basically 1 frame for every ten minutes interval?

Hey Dennis , So I have been watching it all spin in reverse for all these years. It's a Dob's life !!!:confused2: :lol: Nice capture man:thumbsup::thanx:

[Dennis]

Thanks Rick – just let me know if/when you would like to have a go and maybe we can arrange a session where I can run through the set up, capture and post processing stuff.

We can always star with an easy target like our Moon, grab a few AVIs and then run through the processing in Autostakkert2! and Registax as a test run.

Its quite different to DSO imaging, but you get to enjoy the results the same night!;)

Cheers

Thanks Markus – I used Torsten’s excellent FireCapture camera control application and set up a 30 sec RGB sequence with a delay of 210 secs between each RGB run.

So, effectively, these were 90+210 secs = 300 secs or 5-minute intervals.

SO much more comfortable that sitting there with a watch and manually pressing the record button!;)

Cheers

Thanks Wes – I’m still trying to work out which way is up and have downloaded WinJUPOS to help become better acquainted with planetary orientation protocols.;)
