Thank you

Bonjour,
Quelqu'un pourrait m'aider pour tester une commande IR Gentled pour Nikon d70 sans la tête Merlin?
Merci d'avance

Jean-Pierre

Which Gentled IR model do you have? - I have a Gentled-Jump for my D40.

i receive the info.:
J'ai reçu l'infomation de James "Gentled" la voici pour tous:
__________________________
Do this. There are 4 wires:
1. BLACK connect to negative or battery
2. RED connect to +ve or battery (must be between 3 and 5,5 volts)
3. YELLOW, do not connect
4. BLUE, every time you short BLUE to BLACK it will trigger the camera

Make sense?

Yes, that's for the Gentled-Shutter IR device/cable.

Her is what the manual - http://www.gentles.ltd.uk/gentled/Manual-gentled.pdf - says:

"Switch Operation
Alternately (or additionally – as both will work together) you can short the
blue wire to the black wire on the servo connector to trigger the camera.
In this mode the servo connector should be used to supply between 3
and 5.5V to the unit. The blue wire can thus be connected to the trigger
source(s) of your choice."

I am using the Gentled-Jump - http://www.gentles.ltd.uk/gentled/Manual-jump.pdf - which has its own internal battery; it is housed in a small box with a 2.5mm socket and connects to the Merlin head using the camera shutter release cable supplied with the Merlin head.

You will need to find some other way to provide power to your Gentled IR device/cable. I'll be interested to see what solution you come up with because the Gentled-Shutter is considerably less expensive that the Gentled-Jump.

The lathe works ...

I hope next week to get the Orion test head and then we will make a crown to get a maximum clearance towards the horizontal axis.

Hi Andrew, as promised the dismantling of the original older.

Thanks for the clear instructions and photos.

Well, sadly it didn't work for me - I just could not remove the small screw despite heating it with a soldering iron..

So.....patience exhausted .....I burned the big plastic knob away with a soldering iron - fumes from melting plastic not too pleasant - then grabbed the shaft of the camera screw with some grips and the head of the small screw with some pliers and finally managed to remove the small screw and the washer beneath it.

But...the brass insert from the big knob is still very firmly attached to the shaft of the 'bolt/camera screw' - is it screwed onto the shaft of the 'bolt/camera screw'?

Anyway I can still do the screw up and I have plenty of clearance now and with my D40 and Nikkor 10.5 FE can easily achieve full vertical rotation.

What would be nice now is a slightly cranked (dog-leg) rail with a channel in it - like a NN rail - so I could use my NN camera plate directly.

The brass insert is screwed on the Shaft, but as you have discovered you can left the lever part in place.
This is not this part who prevent the full rotation but wel the body of the camera.
Fortunately, You have a Nikon D40 who is very "compact" in comparison of the Canon 40D !

Like the small screw is glued, the brass insert is also "glued" on the shaft by a special glue named 'frein filet" in french (Loctite 243 ?).

They are 2 way for dismantling:
-Temperature (150-200°)
-Chemical

I don't know the chemical used but you can probably find it on the web site of Loctite.

Thanks for the info.

It could be I didn't get the whole assembly hot enough when attempting to remove the small screw. My soldering iron has quite a small tip.

What was that lever part for anyway? - it does not seem to do anything.

By turning clockwise, the lever part give the last clamping (a few extra mm) of the screw after having fixed the camera manually.
This is really very usefull! No need of forcing the screw with a tool !

Merlin not MARLIN
could someone corect the title?
tks
michael przewrocki

MARLIN was the shop here in basel-switzerland where i saw canon 5d mk2 and sx1IS(SX100IS)  WWW.FOTOMARLIN.CH
but we could not try out contax/yashica-eos-adapter(dslexchange) since canon had only 5 bodies around in europe. too risky.

Hi Claude,

Sorry, I can't find it in the posts, what are you using to separate the head from the base and still hold it all together, have you manufatured an insert and using longer screws?  That separation seems like the best place to fix NPP problems.  I see schematics in this thread about a new crown but I dont believe we are talking about the same thing. 

Your enlightenment would be appreciated!

Hi Jason

As explained by Paul in his post http://www.autopano.net/forum/p32400-to … -57#p32400, you can win about 9 to 10 mm on the "A" Quote !

Without modification the Merlin/Orion accept cameras with a maximum "A" quote of 40 mm!

With the separation as explained by Paul, the maximum quote will become 40 + 10 mm = 50 mm !

If, as I presume you have a Nikon 200D, this camera have a "A" quote of 50 mm, this will just pass at the limit...!?!

Explanations of the Camera quotes : http://www.autopano.net/forum/postgalle … Etiers.jpg

Before looking for a replacement crown, you have to tink "deeply" that the limitation of the Merlin/Orion head is the clearance between the vertical part, the horizontal  part and the camera and his support, see herafter:

Hi Paul,

Yes, thanks, that is what I was trying to figure out!

If you are shooting high res mosaics of distant scenes with longer focal length lenses and have nothing close by in the scene then the NPP (and the parallax issue) is irrelevant.
