The AAF3 unit connects via an 8-pin DIN cable to a junction box which has a mini USB socket and connection to a 12V power supply. 12V supply and USB-mini-to-USB- standard cable are supplied.

Just a question like that, I was wondering if anyone has actually done some acquisition of photons with the new AAF3 focuser or you are still trying to figure out how to connect your camera to it ? Maybe someone from the staff at ASA can enlighten us on this one ?

Hi,

 

Made first light yesterday with the AAF3, seems to work ok, one problem is that when I start AS the old ACC software is popping up and I have to run the new version of the ACC as standalone, waiting answer from Dr.Keller how to resolve this.

Added an detailed image of the AAF3 I got from ASA support, there it seems the lock screws will not touch the Wynne corrector, will check if that is true. 

 

Cheers,

Christer

Hi Christer, one quick question for you, is the adaptor that you used to connect your camera to the Wynne corrector, is the same as the one you had for your old focuser (OK3 or OK3 Z ) or you needed to have a new one made for the new AAF3 focuser?

Hi Bernoit,

 

Its the same camera-Wynne adapter as for the OK3Z.

One important thing I discovered, when you should push down the Wynne through the AAF3, with the new camera adapter, you first have to unscrew the 3 lock screws all the way out so nothing is in the way when the Wynne is put in place, that way the Wynne can go all the way to the bottom of the new camera adapter and the lock screws will NOT be applied to the Wynne corrector but insted on the camera adapter part. The screws are conical so I think the will have the effect of push the rim of the camera adapter towards the focus adapter bottom. In my previous image my Wynne was stopped by the lock screws and did not go all the way to the bottom.

I hope ASA support will make some instructions about this, I will put this info on the Wiki as well.

Cheers,

Thank you Christer , really, really appreciate the info because getting info from ASA is like moving trough molasses at -40°C.

Thanks for the info Christer.

 

The adapter/spacer you are using doesn't work for me with the mobile set-up. Undoing the 3 screws whilst holding the camera to stop it dropping to the ground is too tricky!

 

Accordingly I had made up a spacer exactly like the old 45mm one used with the OK3, but 15mm long instead of 45mm. It all works perfectly, and allows safe mounting/dismounting of the camera. See enclosed thumbnail.

 

The set-up has now actually shot some data, and the subs look good.

 

I was also told by ASA that the the new ACC software for the AAF3 only works as a standalone. But I tried it in Autoslew anyway, and it functions exactly the same. Sequence accesses it for AF, and no problems have arisen. Maybe problems will emerge, but until they do.......

Hi MarkS. is the big red wheel came with your new AAF3 focuser or is it part of your old focuser? Also with your new set up, to remove your camera, do you unscrew something (the big red wheel ? ) or you have to remove the 3 little screws ? I am asking because my planned system will be used in a mobile setup.

 

Thank you

 

Benoit

Hi Benoit,

 

The Red Wheel is from the OK3 set-up. The system shown in the picture does not use the AAF3 spacer with the three grubscrews. That spacer is replaced by the one I had made. You can see it on the image between the Red Wheel and the focuser barrel. It screws directly into the AAF3 barrel exactly like the spacer on the OK3 barrel, and the Red Wheel then attaches the corrector/camera assembly in the same manner as on the OK3.

Hi MarkS, a really nice solution to the lacking solution from ASA that does not take into consideration all of the astrophotographers that have a mobile setup. I don't understand why ASA did not go with that solution that uses common sense. I wonder if the big red wheel is available as a separate purchase when someone orders a new 12N ? 

 

Benoit 

 

p.s. do you have the 10N or 12N ?

Benoit,

 

The only drawback with my solution is that the 15mm wide knurled depth is hard to grip as the Red Wheel obstructs it somewhat. This is OK if there is room to fully rotate the camera without fouling the mount. In my case there isn't, but this has not proved a problem so far!

 

I have the 10N

Hi Mark, just to make sure i understand correctly , the  second adapter on the AAF3 normally is 45mm and since the red wheel is 30mm in thickness your new second adapter is 15mm?

Benoit,

 

The second adapter supplied with the AAF3 correctly places the Wynne on the ASA10 or 12. However, it is not really suitable for mobile use where you need to disassemble the system at the end of each session.

 

The spacer I made places the Wynne in exactly the same position as the one supplied with the AAF3, but uses the Red Wheel to attach it, rather than three grubscrews.

 

The OK3 set-up has a spacer exactly like the one I made, but because the OK3 is 30mm less deep than the AAF3, the spacer is 45mm long, instead of the 15mm required for the AAF3.

 

Hope this clarifies the situation for you.

 

Mark

Hi,

 

Anyone got the ACC to work with Autoslew correct with the new AAF3 focuser?

In Add/Remove component I tried "Use ACC" checked and un-checked, when checked two ACC shows up the old and new one, I ignore the old one but a bit annoying.

If unchecked I can start the new ACC standalone, but then Sequence cant find any focuser.

Running AS 5.2.3.1

 

P.Keller had the following comment but same problem as above

"check the Autoslew.ini file and set
[ACC]
Use ACC and take over settings from ACC=False
then run the new ACC standalone"

 

​Cheers,

/Christer

Hi Christer,

 

I am using 5.2.3.1 on Windows 7. I have ACC checked in AS>Telescope>Add/Remove Components, and it works exactly the same as previously with the OK3. Only one ACC window  opens, and it works fine as long as AAF3 is selected.

 

I also have ACC standalone loaded. I have no idea whether or not it makes a difference, but there is an AAF3_ASA ini file in it which I don't see in 5.2.3.1.

Hello to everyone,
 
Still excuse my English :( 
 
I begin to inventory parts : DDM85S - 12 "- AAF-3
It's about focuser AAF-3.

I used the Ikea method adapted for ASA: which introduces into whom?
There is no more red wheel, as planned, but nothing to replace it in my parcels.
Thus it is impossible to rotate the image of the camera !
No part can turn.

I have three grubscrews, and maybe 4 screws for fixation of the system ...
Misses me a part of the rotation system?
 
Thank you for your experience.

From your photos you do not appear to be using the Wynne corrector.

 

When using it and the correct adapter, the grubscrews on the AAF3 adapter hold the Wynne/camera system in place by engaging the seating ridge on the Wynne and its camera adapter.

 

The rotation can be achieved by slightly loosening the grubscrews, and retightening when you have rotated the camera. This is quite safe provided that the seating ridge on the Wynne+camera adapter is the correct thickness. I find this to be quite convenient, and less tricky than with the red wheel system.

 

However, if you want to use the red wheel system, you need to have a different adapter made. See my post earlier in this thread.

Thank you, Mark, for your help.

I had well read your previous remark as for the specific use of the Red Wheel.

 

Two new photos showing the Wynne Corrector.
The (small ?) backfocus of this camera QSI 683 does not allow to install a system for rotation?
 
The red arrow shows a (1/3) conical screw for blocking of the corrector on the focuser.
It would be the only option to turn the camera ...
 
Thank you.
Fabrice
