Unusual indirect sunlight
Hi all,
Ganymede and the Galilean satellites are rarely photographed alone, away from Jupiter. In an effort to capture them now that they have their largest possible apparent diameter, I succeeded this photo and keep trying to improve it and capture the other three as well. Manos Kardasis, a good friend and amateur astronomer provided precious advice, following his pioneer work on Ganymede, back in 2012:. https://www.europlanet-society.org/epsc ... -ganymede/

Best wishes,
Alexandros

Re: Unusual indirect sunlight
WoW!!! You have left me speechless again. The C14Edge is an incredible performer and your processing skills are impressive.
You may be the first amateur to pick up eruptions on Io!! Hey, with this kind of performance it's not unthinkable.

Thanks a lot James!
Eruptions in Io passed from my dreams... I recently asked Damian Peach if he could focus on Io one or more nights, while he is in the Barbados right now and wished him to capture such an eruption. I am right now processing some captures of Io, but I doubt it is within the limits of C14 and my techniques as well. I think it is beyond those, but I will keep dreaming and trying... ;-)
Thanks once more for your kind words!

You may need a bigger scope and/or better seeing but I think it would be possible for you if the criteria was met. The sky is the limit they say...
It's a shame Celestron doesn't make the huge 550mm SCTs they did back in the late 1960's. Imagine one of those with an aplanatic corrector!! A C22 Edge HD!! But you would have to be wealthy to afford one. They made a C16 too.

Re: Unusual indirect sunlight
:-) :-) :-) :-) :-) :-) :-)
It was a dream of mine in my childhood to work in a team of NASA...
Hope they won't stop their activity, because of me! :-) :-) :-)
Anyway, it is true that amateur astronomy has acquired magnificent tools the last years and I still dream of the day that adaptive optics will also become a tool accessible by amateurs!

Re: Unusual indirect sunlight
Alexandros,
I am really surprised that adaptive optics haven't tricked down into amateur hands already. Coupling adaptive optics with lucky imaging would truly bring us up to pro standard with their chief advantage then being larger optics.
But amateurs like You and Christian not to mention several others here already take professional quality images. Just imagine what y'all can do if adaptive optics were added. Professionals beware!!

Re: Unusual indirect sunlight
Impressive results, Alexandros. Very nice indeed.
On the adaptive optics topic; technically speaking the technology is already available to amateurs. But the pricepoint is still as such that it'll be reserved for the lucky few (read: those with very big bank accounts ).

Thanks a lot James and Jochen for your warm comments!
Let's hope the dream will come true during our active lives regarding adaptive optics! ;-)

Jochem, just to keep dreaming or to buy a lotto tomorrow... ;-), do you have any link about such adaptive optics for amateurs to check the results (and see what kind of fortune is needed...)? If yes, can you please send it?

Re: Unusual indirect sunlight
Hi Alexandros.
Have a look at the link below. They're being a bit vague about the pricing (since it's essentially a custom build for whatever telescope you end up putting it on). But during a webinar I attended a few months back, a short presentation of the product was given. On the question of price, the answer was something among the lines of "It used to cost around a million dollars (US), but we're able to do it much cheaper now"; which pretty much told me all I need to know

I have contacted them to learn more.
It seems the 'Fiber Feed Unit' is the only one addressed to amateurs? Hope will know for sure after their answer.
Since you attended their seminar (and hope it was useful and you enjoyed it), did you see any result with amateur telescopes? (on what targets?)
Best wishes,

I think the "Fiber Feed Unit" is basically just a connector to feed into the actual AO unit, but I could be wrong there. As far as examples goes, they showed the typical random stars with and without AO enabled (big difference as you would expect). I'm (obviously) not an expert on all things AO, but from what I understand, small to very small targets (angular size wise) is what you'd be using this on to push the used telescope to or close to the diffraction limit. The use on wider targets would be very limited.

Re: Unusual indirect sunlight
I would love to see what amateurs could do with AO technology coupled with lucky imaging. The limit would be only the diffraction limit of the telescope!!
