Jupiter 25/5/19

[Camelopardalis]

Folks,

First time I'd been ready for half decent seeing this season, after months of cloud and turbulence.

This shot was taken with my Edge HD 11" shortly before midnight.

I've tried to get the colours as close to eye-view as possible, although they're maybe a little more bold :D

Cheers,
Dunk

Good image Dunk,
Looks like you had slightly better seeing conditions at your location. :thumbsup:

[Camelopardalis]

Thanks Troy! Yeah it was a bit random, as it was only clear for about an hour before the clouds rolled back in :shrug:

[Rigel003]

Beautiful image. Nice colours, very smooth and lots of detail.

[Allan_L]

That's beautiful Dunk.
… are you ready for a return visit to Barraba?

[Camelopardalis]

Thanks Graeme! Was very lucky even though it didn’t last long.



Thanks Allan! Never say never ;)

What a Stunner, Like the limb and background separation - or a huge 3D feel to it Dunk, top details collected, & dedicated being there during the good moments, Credits to your time & effort.
Agree, on the bold color :P I can dig it :thumbsup:
Fantastic Image...

[Camelopardalis]

Thanks for the kind words, Bob :thumbsup:

I got some data the following night too, of the "backside", but haven't had a chance to go through it all yet.

[Marke]

Very nice I've been struggling with seeing here the few nights I've been out

[Saturnine]

That's a top image of Jupiter, really like it. Trying to replicate the colour balance to how it appears to the eye is tricky while also getting the colours to pop out a bit more boldly.
Enjoying seeing everyones images of the planet now that it is in season and the Red Spot is providing some changes.

[Camelopardalis]

Thanks Mark, Jeff :)

The seeing is fickle. It's a beautiful clear day again here but the seeing last night was shocking what with that southerly nudging us :shrug:

That’s a fantastic image Dunk. A benchmark shot.
I’m forever trying to get a reasonable image of Jupiter - seems to me to be a difficult challenge to master. How long would a standard video grab take without introducing too much blur from the planet rotation- 1 min or less?
As I only ever use eye piece projection and video crop with my canon dslr and 10” newt the image is at a reasonable size but blurry to say the least. I guess winjupos is important to achieve the best result i’m tipping. Never been able to fully understand it but keen to learn.

Cheers

Thanks Anthony :thumbsup:

I’ve revisited it a little as I think my shot above is a bit heavy on the red :shrug:

The real maker or breaker is the seeing, oh and good collimation and focus are essential. If you nail the latter, then it’s likely rough seeing.

Your sequence length will depend on focal length of the scope and pixel size of the camera, which together will determine how much error you will see, and thus determine how long your sequences could be without noticing the rotation.

This image was taken at about 4500mm with a camera with 2.9um pixels, so to be on the safe side I was capturing 30 seconds at a time.

WinJupos isn’t the be all...if you put blurry data in, you’ll get blurry data out. If you’ll excuse the pun, focus on getting good results from a single stack first. Of course, capture loads of sequences in an evening in the hope that one or more are decent...that’s why they call it lucky imaging :lol:

[S_Pettigrew]

Oh wow, that's awesome!!

[Camelopardalis]

Thanks Suzanne!

[PeterM]

That is really good Dunk!

[Camelopardalis]

Thanks Peter :thumbsup:

[Wavytone]

Um, what happened to the moons ?

As I recall from watching their little disks intently, Ganymede was pretty close most of the evening, and Io had just about completed a transit before midnight...

[Camelopardalis]

Io was nearby but outside of the FOV of the camera at the time the shot was taken.

[andyc]

Very nice indeed, nailed it :thumbsup:

[Camelopardalis]

Thanks Andy!

[Solar]

Awersome:)

[Camelopardalis]

Cheers Ralph!

hey Dunk! its been a long time since we spoke! fantastic image sir! you should be proud :). I imaged last night, my first session for the year also, though im wishing i was up on 25/5 looks like we had great seeing despite cloud! I am still plagued with all kinds of problems with my PC and capturing data all of a sudden, despite no hardware change. But i got something last night at least. Going to do some emergency upgrades / reformat. I'll post mine soon!

[Camelopardalis]

Thanks Krishan! Hope you get up and running soon...
