We've had such good seeing lately in Melbourne (when the clouds are absent), I'd almost forgotten what bad seeing looks like - until last night. Were it not for the rare coming together of the GRS and Oval BA, plus the NEB/NTZ eruption I probably would have given up long before I did. However, at around 7:45 there was a slight lull in the wind and I got a half-decent image. I had to work hard for it, and it's oversharpened more that I'd prefer, but it's an image of the event. There is still a lot more data to go through, but this image is probably the clearest.

 

Next was Saturn, its inner moons were forming a nice line so I captured that, with a nice closeup of the planet. Saturn never fails to disappoint, I always try to extract as much detail as I can.

 

After not enough sleep, I got up for Mars, and got my best image of the red planet so far. It's still not as sharp as I'd like, but I got a clear view of Olympus Mons which I haven't imaged before.

 

Lastly I had a go at Uranus which was close by, and also managed to extract (L-R) Ariel, Umbriel (just), Titania and Oberon from the noise with some extreme levels work.

All images taken with a Celestron Evolution 9.25" SCT @ f21 with 2x Barlow, ASI 224MC, stacked in AS!3 with 3x drizzle, sharpened in Registax, final touches in Photoshop Elements, Jupiter at captured size, Saturn and Uranus 150% captured size, Mars 200% captured size. Moons of Saturn and Uranus shown larger and brighter than actual.

These look fantastic!

Your pics have a beautifully natural and smooth look to them. 

 

What % did you stack for Jupiter and mars

Thanks Brett, I tend to stack on raw numbers, rather than percentages. In this case Jupiter was 7500 frames out of around 27000, or about 27%. Mars was 5000 frames out of 75000, or 6.6%.

Really nice. I especially like the composition of Saturn with its moons.

Well done, mate!

 

Continued interesting wake west of Oval BA. And it looks like that NTrZ is holding its shape…

Beautiful images Andrew! Noob question here: how do you determine the need for employing 3X drizzle in AS!3?

Thanks Rick, it's something I started doing when I was imaging with my 6", I liked the increased size of the image so I could see the changes I was making in post-processing. This continued when I upgraded to the 9.25", and all my wavelet templates are set for it. It takes longer to process in AS!3, Registax takes forever to apply the wavelets, but I'm happy with the process. The drizzling really helps with evincing the moons of Saturn and Uranus, otherwise they are extremely small and hard to spot.

Now that’s a productive night! Great to see you capturing the alignment as well - that outbreak sure is making it’s way fast! I wonder if we’ll continue to see that turbulence elongate behind it.

Great results Andrew, you have been on a roll for much of the year.  You really should set up a nice photobook or calendar showcasing your excellent results for your friends and family.

Christopher says that the oval BA may turn red soon. May.
