Q associated with Leica Televid scopes?

[Herve5]

Hello,

 

Being a happy Leica Q user, I'm considering an association with a Leica Televid spotting scope and the associated interface fixture.

Anyhow, being quite remote from large towns I find myself unable to actually test before buying, which for me is mandatory.

 

Would there be anyone here with such an experience, that could share some words about ease of use, and results?

 

Thank you!

Hervé

Hi Herve,

 

I did a test with my Zeiss Diascope 85 some months ago:

With the Zeiss vignetting is an issue. Would be very interesting how this works out with the Televid.

 

I hope my kids give me some time to retry during daytime. I had a lot of fun with the X1/X2 and the Diascope. A huge advantage of the Q will be the remote control via app.

 

What kind of pictures are you thinking of?

Impressive indeed! Tank you!

 

What I'm considering:

 

- birds, but in a setup where I should react quickly (monopod maybe? I wonder if the autostab feature actually can be engaged in the Q 'birding mode')

 

- theater-like events (circus acts indeed) : dark places where you need to catch the actor in the bright spot, always from afar.

There I can prepare, but I'll really be in the dark and contrast/noise are issues because I need to keep reasonably fast speeds.

 

Now, if really I can see Saturn's rings too...

 

Thank you again!

TK, I saw on your original thread you didn't deal with raw files "on your Linux system": did you try, since then, Darktable or RawTherapee?

Iam considering attaching the Q with the Televid for bird photography too but hard to find more sources on this topic.

FWIW, I decided for a Swiarovski scope, whose interface is compatible with the Leica televid adapter. I still am waiting for the latter, and could verify that without it imaging is really acrobatic (I'm using a tripod plus a monopod on the Q at the moment ;-)

I longly considered various alternate articulated systems that strap around the scope and allow flipping the camera on or aside, but in the end none convinced me, and my current experiments show the Leica adapter will align things much better, also removing lateral parasitic light, and may allow a reasonably fast setup (so I can use the Q normally too!).

When I get the adapter I'll comment here.

I made another try with my Diascope and the 20-60x-Zoom. Vignetting was a real issue (Sorry for not uploading pics, the 500k-limit is such a pain.) As it was already dark I need to redo this.

 

I wonder whether another ocular would help? But how to find this out?

Seems there is already some stuff outside in the internet: http://www.jayandwanda.com/digiscope/vignette/vignetting.html

Hi, pls update over here once u got your full set up.

I called up my Local Leica shop enquire and he said the Leica Q with the Televid can be Autofocus, is it true?

Two quick uploads on ipernity (full sizes jpegs; I could post raws but honestly with this luminosity I think it's useless.

Of course a Moon picture would be something else):

http://www.ipernity.com/doc/herve_s/41668200

http://www.ipernity.com/doc/herve_s/41686314 -that second one has been very slightly corrected for chromatic aberrations in RawTherapee (otherwise the bottom leaf, at the very edge of the field, did show more blue aberrations)

These pics are almost at the closest focus range limit : just a couple of m away, with the subject measuring some 5-6 cm.

 

My understanding and experience with the Q is, we have a dedicated mode ('birding mode') which, as far as I understand, does no autofocus (I believe it couldn't) but allows the up- and down- arrows to activate the focus-helping screen zoom mode, so that without touching the lens you can really fine-tune the scope focus.

I'd say, in daylight with a 'reasonable' scope* you barely need this zooming (unless you want to spend time to adjust); at night it'd definitely help.

 

I don't believe the above behavior changes if the scope is a Leica or not.

 

OTOH I have ordered the Leica adapter, which I feel will be much better than all the tricks I'm currently doing...

 

FWIW you can also check the parallel discussion on image stab here

(*) what is 'reasonable'... I found mine very costly, but still its entrance lens is just 6.5 cm, and weight 1,2kg

Can I check how did u take this two shots?

how come there is "vignetting"?

what is your full set up?

 

Thanks.

I don't know about vignetting.

What happens in the jpeg pics is, the vignating from the Q is automatically corrected (as it'd be also in Adobe, and as it can be, manually, in all other RAW editors); OTOH whatever happens on the side of the scope is not corrected.

 

I for one am pleased with the images as they are; still, what I'll do one of these days is aim at a clearly rectangular target, in order to definitely assess would-be deformations. But I'll do this only when I get the Leica tubular adapter.

 

At this moment my setup is extremely awkward : having the scope on a tripod, I aim and focus, then I bring the Q on a separate monopod, set it in 'birding mode' and 'apply' it against the eyepiece (which explains you see all the surroundings at the edge of the pictures!)

 

My expectation is, with the Leica adapter, at least I'll eliminate the side light entrances, align better, and above all not spend 3 mn setting everything up :-)

 

H.

P. S. if you pm me I can send you the associated DNG files (+40Mo each) but I doubt this'd bring much more than the jpegs to be honest...

Thank you Sir.

the photos looks pretty sharp but I just find it weird with those black circle around it.

I supposed when u got the adaptor, the black circle would be gone right?

I fear not : the black circle is the side of the eyepiece; it corresponds to an useless part of the Q field of view here.

What I expect from the adapter is a better alignment, maybe a bit closer to the eyepiece (so the central, interesting part will be larger) but little more.

Basically, the field of view one gets from these scope is circular...

Leica advocates to use the fake '35' and '50' settings, which quite trivially just crop the jpeg central part.

Now, there are really plenty pixels remaining in the useful area. We can crop indeed...
