Not at a huge distance, but a Terek Sandpiper at 90 meters looks very small. We had good light early this morning for a change, despite the forecast for thunderstorms.
Only about 2,000 mm.

This video of the Great Egret is an extreme close-up which I like to do sometimes. I can only do it with egrets and herons as they will hold still for long periods.

Astronomer can use very high Focal lenghts for imaging the moon or planets ex: A Celestron C-14 telescope has a FL of 3910mm if seeing is very good we can use either a 3x or 5x barlow lens which will give us a focal lenght 11,730mm or 19,550mm. Some imagers in the past have gone well into the 25,000mm on the moon.

I'm planning to get a "heavy duty" telescope for Sydney so that I can watch the local lagoon which is about 1.5 km away. I'm up on a plateau over looking it. This would be a good solution.
I do have a 77x Swarovski telescope eyepiece though and some Televues.

Extremely close

The recent Great Egret extreme close-up more than filled the frame but the bird was about 15 meters away. This Munia as just beyond the closest focusing of the STX 95 at about 7 meters.
It was hard keeping it in the frame.
There is a video here https://vimeo.com/67255369

Hi,Neil
I'm a digiscoping fans in Shanghai, China.
I've read all your post and learn much.You have done a lot of digiscoping.
Used many camaras to digiscoping with scopes.Very good experience.
I also owned lot of camaras and scopes.
Such as Swaro STX95,KOWA lens/scope,Swaro stm80hd,KOWA883,Fuji X100s,Sony nex7,nex6,Nikon D800,etc.And one of my new toys is Sony RX1(with evf).
I 'm very happy to join the birdforum and communicate with digiscoping fans here!
I post one of my extreme digiscoping to you.Cmara is Fuji X100S, scopes is KOWA lens/scope.
And you can see the best resolution of the scope and the camara combo

Welcome to the Group. The RX1 is a very good camera.
Thanks for sharing.

This video was shot with the Swarovski STX 95 mm eyepiece cranked up to 70x. You can see the wide shot of The Scrape at Mai Po Nature Reserve where thousands of birds come to roost at the high tide.
The birds are about 80 meters from the hide.

It's not often to get such clear light out on the mudflats with only minimal heat haze with about 60% humidity.
This red buoy is at least 1.5 kms from the hide so I had to crank up the scope to 70x.

So if I was looking at darvic/alpha numeric rings on waders/gulls/anything through my Kowa 883 at 60x and wasn't able to read them due to distance, could I improve my chances by investing in a camera to boost the zoom?

Yes, I read many color rings and when I have problems due to distance I always take some pictures and many times help me to read the code.
This gull was at 150-200 m. was imposible to read with the teelscope.

It can but is more efficient if you do an adapter like mentioned in http://www.birdforum.net/showthread.php?t=105037 and use an astro-eyepiece that increase the magnifications - I recommend a 4.5 to 5mm eye-piece. Have a look at http://www.pt-ducks.com/cr-telescope...mm%20eyepieces

A camera only improve resighting performance during windy weather when is difficult to red codes due to scope trembling... Another solution is to use a optical buster see it at http://www.pt-ducks.com/cr-telescope....5x_magnifiers and do a search on the birdforum scope forum.

Sometimes it's possible to get the numbers off video clips too.

With good light distance is not such an impediment. These are taken at about 200 meters. The Coucal on the left arrow and the osprey on the right.
This is the video of the coucal

Wood pigeon at 120 meters

I love this thread. I have photographed this wood pigeon this morning, at 120 meters distance. Not as far as Neil's osprey, but a pigeon is only half as large. Magnification 40x, which is the maximum for my scope and camera combination (Panasonic DMC G3 and Swarovski ATM 80 HD scope)

Well done.
Digiscoping has always been about pushing the boundries using various optics so I'm glad people are still having fun with it.

Heron @150 meters

A Grey Heron flying by at ~150 meters distance, overcast/between showers and dull light, but on the other hand the air had little distortion.

Skywatcher ED80 600mm refractor scope + EC20 (2X TC)
50% crop of Olympus OMD-EM5 frame @ISO 1600, ~1/1000s

(Not sure if 150 meters qualifies for being "extreme" but it's probably beyond the range for what most telephoto lenses would capture).
