Jupiter, Saturn, Mars and Uranus - 28/9 August
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. 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 is probably the clearest.
Next was Saturn, its inner moons were forming a nice line so I captured that, plus 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.
