Triton imaged from Brisbane

[Dennis]

Hi

The weather hasn’t been too good for a solid session of imaging, so last night, I thought I’d slew to Neptune and have a gander. Well, after a 10 sec exposure (at prime focus) I was surprised to see a bright object to the right, where The Sky Pro V6 did not show any stars!

I then had a look at Starry Night Pro V5 and lo and behold, I had captured an image of Triton, at magnitude 13.5.

I slipped the TeleVue x2.5 Powermate in and took another exposure of 10 secs just before the clouds came and imaging halted for the night.

The distance between Neptune and Triton is approx 14 arc seconds.

Cheers

Dennis

very cool dennis, might have to give that a go myself... thought i doubt i'll get anything quite like that :P

thanks :)

Very nice Dennis! Great job!

I've been meaning to give Neptune and Uranus another go before it's too late.

Wow, top shot Dennis :clap:

Excellent Dennis.

Fantastic work as always.
:thumbsup:

great stuff Dennis, looks good in mono too, might have to give that a go on Neptune and Uranus - wonder how many of Uranus's little family I can score...

cheers,

Wicked Dennis :thumbsup:

Cool :party:

Very interesting and something different. Love the sensitivity of the ST7's :thumbsup:

Great capture!

Hi Robert

Thanks! I did a little more research today and it seems that fortuitously, I picked the brightest moon of Uranus and Neptune! :D

The moons of Uranus are fainter and from what I have read, more difficult to image as the light from the planetary disc swamps them. Also, I was using the ST7e ccd camera which is vastly more sensitive than the ToUcam, so you’ll have your work cut out for you if using a web cam.

Good luck though, it would be nice to see some colour!

Cheers

Thanks Paul - this is a project within reach of an 8inch f10 SCT from what I have read today. A sensitive or modded (long exposure/cooled) camera makes it easier.

Very well done Neighbour Dennis.

I hope you were wearing the space coat when taking that one it’s out of this world!:lol: ;) :eyepop: Simply stunning, full admiration for your efforts Dennis

Hi Dennis,

Nice capture.

:cool: Dennis ,but a lot easyer than that Comet you where looking for a few years ago:lol: :thumbsup:

Well I gave it a go last night Dennis with the SAC 4.2. No go unfortunately. Too much magnification and not enought experience with the camera I'm afraid. :P That damn moon didn't help either :lol: I did get a shot of Uranus though in 2/10 seeing :thumbsup: :lol:

I will get it though. Your focal length was 6250mm with the powermate? Yes?

Great work Dennis.

After seeing this post i did a bit of search to see if anyone had nabbed this with a toucam and i came accross this http://www.spacew.com/gallery/image003325.html

Hi Netwolf

Thanks for the link, I really enjoy seeing the work of others as it both inspires me and give me new projects to work on. I came across this site earlier and drooled over the Takahashi 9" F12 SCT.

The photographer used the ToUcam for the planet Neptune and then a (more sensitive) ATK - 1HS II monochrome ccd for the moon Triton.

Cheers

Hi Paul

Hmm, I wouldn’t like to attempt something like this with unfamiliar equipment or software; it’s hard enough when you know your stuff. Sorry to hear it didn’t work out – this time.

The C9.25 has a native focal length of 2350mm, so using a x2.5 PowerMate should give 5875mm. My configuration was:

OTA → Motofocus → CCD camera. I’m not too sure if the additional 3 or 4 inches of the motofocus changes the formula? Robert T seemed to experience this with his filter wheel?

Cheers

Np, the ball park figures are fine. I was trying way over that at around 7.5 m +.

I'll definately get there. :thumbsup:

awesome dennis!!
