Hi Tommy,
Welcome !!!
If I have time I will take some photo's tomorrow to explain the "A" value further.

About the crown, the M5 holes in the drawing are for mounting a Manfrotto 357 rail adapter.
If people use other rail systems the M5 holes are not needed.
Drill it yourself so to speak.
So just the disk.

Any votes for that version ?

IIRC Frederic added additional tapped holes to mount his Manfrotto 357 rail.

The idea behind the M5 holes was different originally I believe - if you fancy searching through all the stuff on this in the French side of the forum I think you may uncover why the M5 holes are specified in the drawing - I seem to recall the idea was to mount a flat blade-like camera mounting 'rail'.

Oké, but Tommy needs to know if the M5 holes are needed

Hi Tommy!

A warm welcome from me too! We had a telephone-talk a year ago and a friend of mine bought a Merlin from you.
Because i have some more interested people here: can your cable-connector PC serial RS223-->>Merlin provide 9V for an Aircable Bluetooth stick? Or what could be done about that?

best, Klaus

Perhaps he can quote for with and without?

Or better still perhaps he can quote for without, then the cost of any additional tapped holes (per hole) to be specfied by the customer?

It would be nice if they could suply with the disc of red friction material already applied so that customers do not have to cannibalise it from the orginal crown.

Good idea Andrew !
So:
1)Plain disk
2)Plain disk with anti friction material

99)Disk with M5 holes (specified by customers)

Called this 99 because it's cheaper and easier to make 1 version.

(I moved your posts here, because the other one is dedicated to the electronic interface).

About the M5 holes, before drilling them, I suggest someone check the diameter for the Manfrotto mount; I think it should be closer to 56mm, rather than 54mm... Maybe 55mm...

I thought you had one mounted on a replacement crown made to Thierry's drawing?

I am not all convinced that the Manfrotto 357 is a good general choice of rail on a replacement crown.

It much be at least 10mm thick/deep so using it you will lose quite a lot of the 'gap' gained by replacing the crown.

It is OK if all you need is to provide more 'gap' for a lense with a large diameter barrel.

Hi Frank,

In order to give a direction for modification or not in function of the dimension of your camera, please have a look on the following place in the Wiki:

Thanks Claude,
and hey..... the 450D is perfect in line :-) according to the list, and it is..

But not my 5D + I need a longer rail for "macro" shots.
Lajos, Tommy's partner at Telescope-austria, is calculating prices right now for a crown replacement.

Any news about the BT module ?
(perhaps a separate topic about BT ?)

hello from Austria,

The calculation is like that:

1.crown plate like in the drawing
http://www.autopano.net/forum/postgallery.php?pid=31556&filename=rotator_merlin_drawing.jpg
sandblasted and anodized €39.- per piece

2.same, but blank aluminium, not anodized €32.- per piece

Drilling of the holes would be individually up to the specified needs.
(not all of you use the same camera mount, don't you...?)
Prices for shipping added.

This prices are calculated for a minimum of 10 pieces, if we can sell we could drop them a little, of course.
So it would be of interest to get an idea of how many are needed. Everybody interested please
should email me and give a short notice, or post it here.

How important is a friction-increasing surface? Could you do it yourself if you need it? I saw
a post somewhere that it is of concern.

all the best, Tommy

one for me please, the 39,- euro version.

Can some one confirm the drawing ?

For friction material, can thin rubber like bicycle tire-repair stuff be used ?
Just an idea.

For the friction, just remove the one from the original crown with a thin blade (be carefull not to break it), and stick it on the new crown (the old glue will be enough).

It seems there's not much interest for this new Teleskop-Austria Merlin Crown Disk :-(
I'm still the only one ordered one....

Hi Paul,

Do-you have more dimensions from Bader Planetarium ?
I think mainly to the diameter of the central hole for the axis and to the thikness of the crown only (montageplatte) without the clamb (aufnahme) and without the dovetail (schwalbenschwanz).

Thanks

Claude

Frank,

I don't need one with my current camera and lenses - but I would buy one if they were able to supply it with the friction material attached and if I knew what they would charge for custom tapped holes and what the carriage cost would be and what the delivery timescale would be and how I could pay - bank transfers are ridiculously expensive from UK to the Eurozone; PayPal would be acceptable but not sure they offer that option.

I'm reluctant to cannibalise the standard crown for the friction material and risk damaging the friction material ending up with no functional crown/head at all.

The 'solution' they currently seem to be offering is far from complete and is not 'plug-n-play'.

I have the impression that they don't really understand what we are doing, nor do I think they have any real interest in providing a complete solution.

Hi everybody;

Andrew, I am in agreement with you.

If there are improvements in the proposal, and I can pay across PayPal, I would be interested too.

All the best,

Joni.

I am afraid a plug and play solution is not possible.
It depends on the camera YOU will use and a railsystem YOU prefer.
About the fiction material I agree, but with some other stuff you don't have to cannibalise the standard crown I think.

About payment, yes the Paypal way is an easy way, but just ask them..
A PP account takes 2 minutes......
But hey, UK guys, you could join the Euro long time ago...... :-)

I meant that basic crown 'disc' should be 'plug-n-play' - that said if they were serioulsy interested they could also have proposed a series of rails with QR mounts for common cameras as well.

.........

I wish we had joined the Euro years ago.

It's a matter of numbers.
How many people on this APP forum have a Merlin/Orion.
How many of these people need a crown modification.
How many of these people have the same sized, "common" camera.
How many of these people use the same railsystem.
etc.

You can't expect from the teleskop-austria team to devellop a Nodal Ninja solution for shifting the A value, just for 5/10/20 ?? clients.
It's not their main business.
With a less thick crown you can drill anything you want on that disk and if you don't have the tools, hire/ask someone to help.
A basic crown for 32 euro is a fair price in my opinion.

No, I didn't get that question answered.

I think Tommys offer is good solution as they are interested to support the Merlin users and it is a fair price too.
