Jupiter 29th April from Melbourne

[Maurice]

Hello everyone

Here's a shot of Jupiter taken on the 29th April UT in reasonable seeing from Melbourne. Good seeing has been quite the exception to the rule this year...

GSO RC14 @F/20, ASI 290MM camera, Astronomik RGB, EQ8
Sorted & stacked with AutoStakkert 3! WinJupos derotation of RGB sets
VC Deconvolution + IRIS

Cheers

And people say that an RC cannot do planetary
Very nicely done.

Good to see you imaging again Maurice.

Wow. Its unimaginable that amateur rigs are making images like this.

Good to be back John...if only briefly. I'll be out of action for a couple of months soon...getting old can be a real pain sometimes...

Great work Maurice, GRS region showing a lot of detail.

Not bad Maurice. The colour looks a little washed out but the detail is pretty reasonable. Do you think you will get a Mars image like last 25" opposition?

I saw Jupiter myself for the first time the other night in what was reasonable seeing until I setup and then it slowly went to pot. Not like the heady days of 2006-2008 when the seeing was on tap. Good to see an RC imaging. I have been contemplating selling my C14 and getting an RC16 for this very task. Cooling it might mean working on a new modification to the RC though.

Unless the seeing improves, I don't think that there is any chance of getting a Mars shot like those from 2003.
The RC probably isn't the best choice for planetary work, but I do have plans of making a new smaller secondary just for planetary work. The best design so far looks like it will make the whole system work natively at about F/17.5
Central obstruction reduces from about 42% to 30% (limited by the baffle tube/central hole in the primary).
Cooling is always an issue, but it seems easier to manage in an open tube design than in an SCT.

cheers

Nice picture.
Looking forward to any images from last night
as the dark spot in the NEB was so pronounced
when I observed it in my 16" at 180xmag.
Cheers
