My best Ghost of Jupiter neb. image ever

[tornado33]

Hi
Here is a giant image of the Ghost of Jupiter, and possibly the highest resolution DSO ive ever done
I used a 2x barlow, on the 10 inch newtonian, so fl was now f11.2, and I used Drizzle 2x upsampling in Iris, so fl became effectively f22.4. Focal length 5600mm.
Its 10x2 mins ISO400, uhcs filter, hand guided using q guider cam and tracking guidestar manually on laptop monitor.
Processed in Iris and PS

Whoa! Crikey Scott, talk about pushing the envelope with backyard equipment. :bowdown:

[h0ughy]

WOW now that is a fairly ordinary shot Eh Scott:eyepop::eyepop: :jawdrop: :jawdrop: (my goodness me I nearly soiled myself when I saw what he produced!!!)well mate, I think you could do better tonight:whistle:

[Ric]

Wow, what a beauty Scott well done.

The level of detail and colour you have captured is simply amazing.

Top stuff

[Dennis]

A beautiful photo Scott – just lovely to look at. You’ve done a great job in capturing and processing the beauty of this object. It must have been quite close to an almost full Moon?

Cheers

Well Scott, I was wondering who was going to get my 3000th post, and you have won it with a simply awesome image, :eyepop: that is text book stuff. ;)


Leon :thumbsup:

[tornado33]

many thanks all.
yes the moon was near full. Thankfully it was a fair way north and the house stopped any direct moonlight from entering the telescope.

A real feel of resolution in that shot Scott, the extra FL helped for sure. It may be a bit monochrome green (?) but a really lovely image all the same :thumbsup:

Wish I had an obs so I could take advantage of the holes in the clouds.....:(

Outstanding image of that nebula

[tornado33]

Thanks all. In hindsight I might have been better off without the nebula filter as some broadband emission might have been recorded reducing that monochrome green effect.

Well the clouds have returned again, how long must we wait for another imaging opportunity

You have done a amazing job of it Scott. :eyepop: I bet you are enjoying guiding from the laptop! I know my neck feels 100% better after a night out!
cheers Gary

A seriously good image, the small items (in this case 64 arc seconds) are difficult to get any detail on. particularly when faint as you cant whiz through frames like shooting jupiter.

Stunning shot Scott !

Nicely processed too, very smooth.

:eyepop:

[EzyStyles]

great shot scott, what kind of 2 x barlow are you using?

[Tamtarn]

That's stunning Scott. Smooth and clear wonderful image with a DSLR :2thumbs:

Like Ezy we have a question regarding your use of the barlow.

We wondered about focus and the intravel of the focuser. We just have a Crayford 10:1 focuser and we have about 5mm intravel left. Which type of focuser do you have?

[tornado33]

Thanks all
I bought the barlow from Mark Sutching at the last Lostock. Its an "orion" brand, has good coated optics and is quite heavily built, with 2 solid screws so easily holds the dslr. Focus comes out about an inch further so thats okay. When I saw it at Lostock I had an idia that as it is so solid it would come in handy. Its so solid I reckon a person could amost swing from it.

Only bummer with a barlow is that as it has the camera further out it unbalances the scope a bit, requiring rebalancing. I have a cheap "generic" brand 2x converter but its rubbish, adding blurring rather then kust magnifying. There is no vignetting with the Barlow too :)

here is my focuser/off axis guider unit http://www.users.on.net/~josiah/focuser/IMG_9933.jpg
that was about what I had it when the Barlow was in. With just prime focus its racked further in, about 10 mm poking out from the outer focuser tube

That looks kinda special Scott. Quite a serious bit of machinery there :thumbsup:
Thanks for the info we'll check out our Orion barlow with our 8" Newt and give it a try in the future.

Thanks for taking the time to post

Scott,

that is one to be proud of!
so you also used a barlow for that PN. I have gathered some experience in using barlow lens for PN imaging. I am glad to see, there are more people using them for DSI as well. the result tells me, seeing must have been pretty good.
congrats on a great PN image!

[robin]

Exceptional image Scott.

[theodog]

Very, very nice Scott.
Plenty of detail and nicely coloured.
Well done.

[tornado33]

Thanks all. I think ive squeezed about all the resolution I can out of the ol 10 inch. Not bad for a 22 year old telescope and mount :)
Scott

[h0ughy]

said scope and muscle man:rofl::rofl::rofl:

[strongmanmike]

I particularly admire the old brown leather belt holding the scope together :)

Looks like a nice new OTA, hardly used..?

Mike

[RB]

LOL the Argo can now play MP3's ???

hmmm iArgo :lol:

Gary how can I upgrade?

[tornado33]

Yup thats me and my rig. The belt come in handy for lifting the OTA onto the mount. It lives in the garage when not in use, only the mount stays in position. I listen to FM radio while guiding, makes the time go faster :)
In the off axis guider you see a 32mm erfle, I use that for locating a guidestar, centre it then replace it with the 2.8x barlow and q guider. I cant use the qguider witout the barlow as I cannot get enough back-focus without moving the primary mirror up the tube but that might mean vignetting so I use 2.8x which gives huge guidestars.
As you can see the telescope is 22 years old . The OAG assembly is newer though, only a few years old.
The OTA's Sutching mirror is on its 3rd recoat. First 2 were Astro Optical Supplies done (quite good mind you) but not overcoated. Current one was by Issac of Chi Qin Co, with a beautiful electron gun applied quartz overcoat, that should last the life of the scope (or me) :)
