Wow Mike, that is a beauty! Well worth the wait.

I like the 4 sets of rings and that is a smart idea to bolt them to the
focuser to add rigidity.

The tube seems nice and thick. Is the scope visibily a lot different in design to the ASA?

I think you'll be fine on the NJP although you will be a bit beyond its design limit. Just make sure its well balanced. You may need an underscope end counterweight if you put a guide scope on top as that will make the scope's balance point shift with the angle which can complicate things. Although I suppose if the guide scope is kept dead centre of the scope axis it shouldn't do that.

A MMOAG would be my guiding choice for that baby rather than a guide scope but then again it adds weight and takes up about an inch of backfocus. But it does get rid of flexure not that you have a problem with the AP and this is the same or close to the same focal length. Plus talking with Don Goldman about adapters is tiring. He must have 10 million of them.

I can see some awesome images coming up.

Looking forward to your first light. Take your time and get a superb first image out of it. Lots of flats and trial and error on best way to handle it.
I found the CDK easy to use but it had its own learning curve and it took me a while to optimise images out of it (flats were always the problem).

Greg.

Hello Fred, nice to hear from you

Yes, tis not only me that maketh funny photos of fellow IIS'ers

So far the scope looks to have better solutions than the ASA in a number of areas but only time will tell....

You will get great diffraction spikes that's for sure. You wont get any flexure on your secondary.
Yeh diffraction spikes will be something I am not used to...although, I used to put sticks across my 12" LX200GPS and ED80 to induce them so maybe I have a secret diffraction

I am quietly confident that the NJP will be ok, you can see the ASA N12 in the image below (she looked pretty good too huh?) in the same configuration the AG12 will be, similar camera too although the AG12 will be heavier due to the extra weight in the support rings, focuser area and the main mirror mount too. Although the images were astigmatic during this (the last) ASA N12 imaging session , the tracking was the same missile tracking quality the NJP is so famous for

Don't worry I am certainly planning on taking my time with this to make sure I do everything right. I will be moving my setup from Kurri Kurri back to my mums place in the next suburb here in Newcastle as she has open skies and a lockable garage where I can comfotably shake the scope down ...once whe is tried and tested I will move back out to darker skies (well that's teh plan anyway )

Given you're probably one of the few astronomers in Australia (or the world) who could carry one as a portable mount, wouldn't an "el Capitan" be more appropriate? They're accepting direct orders with delivery in 2-4 weeks!

Yeh could be a bit funstration me thinks but being at my mums will be a nice change, will be nice to have a kitchen at my disposal in the middle of the night again , I haven't had this luxury for some three years now, been thermos and eski

Yeah I think you're right Mike the NJP should handle it. It will be close to its limit though. You also seem to get excellent tracking. Balance will be the key with this one. I could get reasonable results with the 12.5 inch RCOS and I think with the MMOAG it would've been even better.

My NJP handles the TEC180 quite well and that is a fairly large scope. It handled the Tak BRC250 which is quite a chunky if stubby scope.

Looking forward to some reviews and images.

Have fun!

Greg.

Mikey, nice looking scope. You look your usual excited self.

Not sure about the NJP. A decent gust of wind and there goes that sub or worse that tooth. I imagine that it will be a stop gap until you decide on a particular mount. The numerous bar weights are testimony to how much weight it is swinging. So you have to think about the teeth on the drive.

That said I will no doubt be eating my words, but as a person who has taken risks and come out trumps in Astronomy I await your testing of the scope. Best of luck.

I have just added some of the mirror cell installed and the Atlas and corrector in place testing the Atlas - at the bottom of the album here

Cheers Greg and Paul.

I am confident the NJP will cope, this was a mount way ahead of its contempories . I imaged the Witch head nebula in very strong winds and the NJP just sliced straight through the heavy (scary) buffeting.

I hope it is ok

Mike

It looks great. Is the Atlas much beefier than the PDF? I have a PDF (which I am not using on my setups now as it was more for the Tak BRC)
and it is quite beefy. Its also a nice unit and works really well.

Is the corrector held in with the 8 nylon screws? Is this a Keller corrector or one OOUK make or get made for them?

Looks like you are ready to collimate and first light eh?

Greg.

Looks very fit for purpose Mike. The wait is over, but the nervous stuff begins. Fingers crossed the focusing train is flexure free at all angles with that FLI kit (which is a common challenge for any scope of this type, stating the obvious).
Do you have the ability to level the focuser base in some way? I'd assume that f-ratio and big chip will be utterly unforgiving of tilts.
Does the Wynne (attached to CFW) just snugly clamp 'inside' the Atlas? or is is screw fitted in some way? (I may have a use for an Atlas perhaps)

Looking forward to seeing a swathe of ground breaking deep southern sky images.
cheers, guy

(PS it's miserable & snowing here in Canada as I write - glad I'm going back to Oz tomorrow)

The Atlas is apparently in a different league to the PDF and it looks so but only time will tell, can't deffinitively comment yet.

Yes, the corrector is held in by the 6 nylon screws. The fit of the corrector is very snug with almost imperceptible movement before locking it down, as I said the workmanship is first rate as far as I can see so far.

No this is not a Keller corrector it is actually a little larger and has 4 elements but is quite similar. The optic manufacture is outsourced but the units are assembled at Orion and yes the element edges are blakened - it looks pretty good.

Hi Guy, in wintery Canada huh? brrrr

So far the enginereing looks on the money, I can not see a week point in the design of the image train yet but only time will tell, suffice to say the focuser assembly looks nothing like the flimsy JMI kit that was on my ASA

No (easy) ability to level the focuser base but Orion have assured me they were maticulous in setting up this aspect..again, time will tell...

It really does look the money but I am reluctant (well I can't really) to sing any performance praises until I have thouroughly tested her out...in my mums backyard ...everyone will see, my cohones are on the chopping block you could say

Peter Shah received his AG12 a couple of weeks prior to me and he has already shaken it down and produced this rather short exposure full 11002 frame image (look at all the background galaxies!) so I live in hope

Mike

I didn't realise your ASA had a JMI focuser - that would really be pushing it. Testing the 12 locally is very wise. (just been at a Toronto mining conference with 27000 attendees estimated - crazy!)

Peter Shah's image is very very good.

How do rotate the scope to frame the image? Does something loosen and you spin it around?

Simply losen the grub screws and turn the corrector in the adapter (the fit is very snug) - easy

I see. You would be smart then to install a lanyard on your camera.

My ML8300 slipped out of the eyepiece holder when I was imaging with a
Tak 1.6X extender and a specialised adapter. When temperatures fall something that was tight can loosen unexpectedly.

It is being repaired at the moment.

A lanyard to protect the camera and filter wheel makes a lot of sense.

Greg.
