Again an amazing result. I only know these kind of resolutions from amateurs who are working at the Pic Du Midi, France at approx.2800 m above sealevel. I wouldn't have thought about Bangkok as a great location seeing wise. You proof i am absolutly wrong.

That i one of the best iages of Jupiter iv seen. still for some reason in my opinion it seems to lack detail it looks very bland

Hi Tiziano,

 

So much detail on Mars, and Saturn's C ring appears to be showing multiple divisions, I never observed that in a Saturn image before.

I like that you hold on to gamma levels and never over-cook contrast. You make planetary imaging look easy. Enjoy your new scope.

 

Cheers, Dan cool.gif

Fantastica!!!

 

wish i can build scopes like that to have similar results, i am still thinking about C14", but this scope sounds a kicking..., if it is available and cheaper than C14 then i will get it instead of C14, the results sounds no less than C14 anyway.

Hi Tiziano,

 

Looks like you're off to a prosperous image-posting future over at ALPO Japan and, again, huge congrats on the new gear and the great results you're achieving with it! :D It must be nice to be working at ~f/20.8 with your setup vs what would be a full-stop dimmer of ~f/29.5 (and with less angular resolution) with a C14 at that FL!

 

A quick question, I'm guessing the edge-ringing artifacts (as seen along Saturn's and Mars's periphery as double horizons) are an inevitable consequence of local atmospheric turbulence (captured in each single image frame) being stacked multiple times?

 

Thanks so much for sharing your images here, they've been very educational (well, at least to me!) as to what's actually possible with this level of aperture!

 

Continued success! :)

Jimmy G

Dear all,

after a long absence I've finally completed my new telescope, and I was blessed with a good night. It took me almost two years to design and build the telescope, a DK 505 mm f/20,

in fact a larger version of my previous 410 mm DK. However moving to 20" is a giant step, the mirror is 60 mm thick and heavy, therefore it requires a solid structure. I'm still using my trusty AP1200, it's at the limit but working fine.

This is probably my best image of Jupiter, I moved to a new camera, Point Grey GS3 with Sony IMX252 with larger image scale and lower noise.

Thanks for the attention and best regards

Tiziano

Hello Tiziano. 

I love that little orange oval within the South Polar Zone.

It's like a miniature "red" spot.  

 

Aubrey.

Absolutely stunning images! But I have to ask - how is Jupiter using an eyepiece? 

Congratulations on a fantastic instrument. Really, really nice work!

 

Best regards,

Sorry for the late reply but I was travelling during the last 3 days.

 

Thank you very much for your enthusiastic comments, it's a pleasure for me to share my works to this community.

 

To answer some of the questions:

@Traveler: seeing in Bangkok can be very good, because is on a flat and my house is not to far from the sea there is little turbulence. The best conditions are when the wind blows from the south. The main concern is the transparency normally poor due to the low elevation (5 m above sea level), and the horrible light pollution. The monsoon season last for 6 months when it's almost impossible to take images.

@TareqPhoto: this telescope is custom made by me, and certainly costs much more than a C14. It's not commercially available and also requires a sturdier mount because of the weight and dimension

@Jimmy G: the limb artefacts are difficult to eliminate, some are due to the turbulence, and others to the derotation. The artefact typically appears where there is an area of high contrast and it's due to the unsharped mask "bounce" effect.

@Mike Spooner: I don't observe much at the eyepiece, but the planet look very steady when the seeing is good. I don't have a good planetary eyepiece as well, I prefer to use the time of good seeing to collect images.

 

Best Regards

Tiziano

I don't think there are words to describe these images! 

 

Tiziano, do you find that poor transparency has a detrimental effect on your imaging or would you say it doesn't make a difference?

If I may jump in. Poor transparency is like imaging through cheesecloth. The seeing will be very stable, but depending on how much gunk there is, it may as well have been imaging through clouds. When seeing is very good, and transparency is crystal clear, details pop!

Thanks for the last comments, 

regarding transparency vs seeing, obviously it's better to have both, but it's very difficult because the conditions of high pressure and stable air are not conducive to great transparency, at least from my location. Pic du Midi seems to be excellent from both accounts, that's why the best planetary images are taken from there.

Regards

Tiziano

Great images, actually funny thing is, you made me go for a 20" scope myself (just deposited it today), and to go to Thailand hunting for real-estate and be there at least 3-4 months a year. No kidding here, I have the plane tickets to Bangkok for the 1st July grin.gif  By the way, what do you think about the seeing compared to Bangkok in Koh Chang / Samui islands, I'm thinking of renting a small house / flat with huge terrace from next year there?

 

I know it's off topic, but if anyone has experience regarding to Tenerife's high elevation (90 min drive from the place where Damian made his trip), or Barbados vs. Thailand, I would appreciate. I also go to visit Tenerife before Thailand to look around, lucky I have friends both in Thailand and Tenerife. I might need to have a new friend in Barbados as well lol.gif

 

One more question: how did you send your scope there from Italy? DHL, UPS, plane?

 

Thanks,

Gabor
