Hi there, I was able to colour calibrate my laptop screen using one of those USB "spider" assemblies that ensures the colours you see are "correct". What a difference it made! My previous gamma setting was way too high, everything was far too blue and blown out, and now I look at my old images and cry a little.

 

Anyway, after I settled down a bit, I tried a bit of imaging last night and here is my best Jupiter with a couple of moons thrown in.

 

Imaging details: Celestron Evolution 6" SCT, 2x Barlow, Canon 700D DSLR, 5,000 images at 20 fps, pre-aligned in PIPP, 50% stacked in AS!3 with 3x drizzle, sharpened in Registax, and final touches in Photoshop Elements, final frame size 25% larger than actual

 

[EDIT] Aargh  ! That should be July 3, not June!

Very Nice !

Can't believe this is taken with 6" scope.

Very nice result (especially the subtle hue contrasts in the NEB). And that settles it…you've inspired me to shoot Jupiter again tonight. It's been a week since I've imaged the GRS because of a raging jet stream, and I was vacillating between planetary or DSOs tonight. But the jet stream is in the slow 30s over the Red Centre at present, and the GRS transits close to midnight at zenith.

 

Cheers,

Hi all, thanks for the likes and comments. This image might still be a bit over-sharpened, but I do prefer to see stuff than not .

 

Very Nice !

Thanks Mark!

Thanks Tapio, it is, honest  .

Thanks BQ, it was quite early last night, the GRS was central at about 7:30, the only reason I went out was the single digit jet stream figure   and I had a new version of BYEOS to try. 

 

Good luck tonight, I might give this one a miss tonight myself

Single digit jet stream! And here I was excited about mine being in the 30s! It's been exactly a year to the day since I've had single digits without clouds.

 

Tomorrow's transit will be much earlier…hopefully your seeing holds.

 

Cheers,

Very nice!

I also invested in a Spyder recently, very useful little device.

Now I just need to track down all of the "helpful" Win 10 system functions that alter the colour balance depending on ambient light, time of day, which way the wind is blowing, what I ate for breakfast etc etc ... every time I think I've found and disabled them all, another one rears its ugly head lol.

I had another go at the colour rendition, the first image is probably still too yellow/brown.

 

Any comments on this one instead?

 

Thanks, Andrew

The "right" color for AP is a hearts and minds campaign.

• Heart: Do you like the result?
• Mind: Does the histogram match your target?

As for my assessment, your image is extremely useful. The crisp detail (from good seeing and focus) and high contrast luminosity (from processing) lets me see what's going on with the GRS-SEB interaction (refer to my animation on the 1st). The streakline over the GRS broke apart around 6 June; yours shows a wisp of a reconnection. In deep red, at that (whatever that means chemically).

 

The progression from yours to mine from yesterday is also notable: there is a blade that appeared within a day on the southeast side of the GRS that seems to extend south deep into the SEB (yours has a hint of a bulge whereas mine has a full blade extending south). I'm hoping one of the big guns had good enough seeing to post a result from the same timeframe to better see what's going on…
