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
Scott
WOW now that is a fairly ordinary shot Eh Scott (my goodness me I nearly soiled myself when I saw what he produced!!!)well mate, I think you could do better tonight
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?
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.
Scott
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
Wish I had an obs so I could take advantage of the holes in the clouds.....
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
Scott
You have done a amazing job of it Scott. 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.
That's stunning Scott. Smooth and clear wonderful image with a DSLR
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?
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
Scott
That looks kinda special Scott. Quite a serious bit of machinery there
Thanks for the info we'll check out our Orion barlow with our 8" Newt and give it a try in the future.
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!
