Answer: "It's a Tele Vue."

Pheasant (Phasianus colchicus)

The question being, typically: "What's that on the end of your camera?"

As the name of this blog suggests, I do most of my photography with a telescope - a Tele Vue-60 refractor to be precise. What it lacks in autofocus and aperture control it more than makes up for in sharpness and colour correction. It's compact and portable and it doesn't need to be stopped down to hit the sharpness sweet spot. Recently Tele Vue embraced the world of social media and - as part of their ongoing 40th anniversary celebration - they asked if they could feature me on their new blog, in particular why I chose the TV60 and why I've stuck with it over the years. You can read the resulting post here:

Three scopes in one: astro-scope, spotting scope and telephoto lens

Astronomers of course need no introduction to Tele Vue, but for those who don't know, they're a Chester, New York-based company founded in 1977 by Al Nagler. Prior to that Al designed lunar landing simulators for the Apollo missions, using his knowledge of optics to create realistic wide-field vistas to aid the astronauts' training.

Tele Vue started out making lenses for large projection-screen televisions, but they've since become renowned for their high-quality eyepieces and telescopes. If you ever get the chance to look through one of Tele Vue's wide-field eyepieces, I highly recommend it. They call it the "spacewalk" experience and with good reason: if, like me, you started out in astronomy squinting through a cheap and cheerful 0.965" eyepiece, the difference is startling. When looking through a Nagler it's as if the eyepiece "gets out of the way", leaving you immersed in the stars (or suspended above the moon if lunar observing is your thing). And if the 82-degree apparent field-of-view of a Nagler isn't enough for you, they also do an Ethos range, which goes up to a whopping 100 degrees.

In the interests of fairness and transparency I should point out that:

a) Other telescopes and eyepieces are available
b) I was not offered any incentive by Tele Vue (financial or otherwise) to contribute to their blog or write this post. I'm just a proud TV-60 owner and I wouldn't dream of parting with it.

A few thoughts on Google's Nik Collection

Back in March, Google made the entire Nik Collection photo-editing suite available as a free download. Despite my initial scepticism (and wariness of filters that claim to replicate the "look" of film), I have to admit - now that I've been using it for a few months - it is actually really good and serves as a helpful complement to Photoshop. The Control Point technology is particularly useful for carrying out localised enhancements, saving a lot of time compared to manually creating masks.

Selective sharpening using colour range masking

Of course, no amount of software wizardry can turn a bad photo into a good photo, but with a little care you can get some interesting results, as shown below. (Note: my photo-editing steps are usually a lot more subtle than this. I provide these photos as examples because it's easier to see the difference.)

Move your mouse across the images to see them as they appeared before processing. Most of these results were achieved using Color Efex Pro, but the first image (the helicopter over the house) was enhanced using Silver Efex Pro to create a High Dynamic black-and-white luminosity layer.

The complete Google Nik Collection suite is available at:
It works best as a Photoshop plugin (under the Filter menu), but you can also run each application as a standalone program if you create short-cuts to the individual .exe files.
