Thanks to this thread on CN, I recently learned about Optical Instruments, a sort of online clearing house for optical gear from Explore Scientific, Explore ONE, Bresser, and a few other instrument makers and resellers. In particular I was taken by the screaming deal on the 60mm Bresser spotting scope. I’ve had a lot of fun scoping birds with my telescopes (most recently with the C80ED), but I thought it would be nice to have a light, rugged all-in-one spotter for camping and hiking. And at $39.99 with free shipping, the price was certainly right – normally the scope lists for over $100. I placed my order on November 25, got a shipping notice on December 3, and the scope came in today (well, yesterday, December 8 – I’m up late).
I got the scope out for a few minutes late this afternoon for a test drive. It’s solid. The eye lens is nice and big and the objective has purplish anti-reflection coatings. Optically okay – the image does go soft in the outer 10-15% of the field, and there’s a bit of chromatic aberration, but neither problem is severe enough to put me off. The eyepiece is not quite parfocal across the zoom range, but it’s close enough that I just need to touch up the focus a bit after changing magnification. Fit and finish are merely serviceable, about on par with inexpensive Celestron binoculars. It certainly doesn’t have the feeling of machined perfection that you get from a nice telescope, but part of that may be the rubber armor (which I’m more happy about than not, as I intend to use this scope).
Here are a couple of unboxing photos with the scope still in its case.
Five features I really like:
- Padded view-through case – this has cutouts for the mounting foot and focus knob, and the covers for the objective lens and eyepiece snap off, so in bad weather you can leave the case on while viewing.
- Sliding dewshield for the objective lens – I’ve only had my scope out on a cloudy day just before sunset, but I’m sure this will come in handy for cutting down glare on sunny days. This is extended in the first picture at the top of the post, collapsed in the second one.
- Twist-up eyecup on the eyepiece – nice for visual, great for digiscoping as it helps get the distance from the camera to the eye lens just right.
- Mounting foot on a rotating collar – super useful for side-mounting. The focus knob is on the right side of the scope, so it’s better to put the mount on the left if possible. I used a Universal Astronomics DwarfStar mount for testing, first with the scope upright on an L-adapter (second photo above), and then later on side-mounted using a spare footplate from a Manfrotto ball-head as a makeshift dovetail bar (see next photo below). One thing to be aware of – the cutouts in the case for the focus knob and mounting foot are fixed, so you can’t have the view-through case on if you side mount the scope.
- Side-mounted focus knob – most spotting scopes have a little knob in front of the eyepiece that you roll side-to-side to focus. I’ve never gotten the hang of that; I’m always struggling to find the right amount of pressure to turn the focus knob precisely without pushing the scope off-target or shaking the view. The side-mounted focus knob on the Spektar makes it feel just like using any other refractor, in that I’m reaching my right hand forward and rolling a focus knob. Lefties may not be so wild about this.
Here’s a photo showing the scope side-mounted, with the mounting foot facing left from the eyepiece and the Manfrotto footplate ‘dovetail’ (lighter grey metal) serving as a dovetail bar. The lock knob for the rotating collar with the mounting foot is facing straight up here, and the larger, right-mounted focus knob is also visible.
Now, five things I don’t like:
- No pictures in the so-called instruction manual. Until now, I’ve always gotten a chuckle out of the labelled photo of the assembled scope in most telescope instruction manuals – sheesh, who doesn’t know what the eyepiece is? But now the shoe’s on the other foot, and I’m not laughing anymore. This scope has some non-standard features and you’re basically left to figure them out by trial and error. I did that, mostly successfully (but see below), but it’s still an irritating oversight.
- Just below the eyepiece is a knurled ring that rotates. I don’t know what it’s for – maybe it’s a lock ring to hold the zoom eyepiece in place? I haven’t had the courage to unscrew it and find out.
- The rotating collar and lock knob feel very plastic-y, and the lock knob does not come to an authoritative stop. Instead it sort of oozes into tightness. I’m worried I’m going to overtighten it and either strip the threads or break the knob.
- As people on CN have noted, the soft rubber dust cap for the objective lens is a loose, floppy joke. At one point while I was unboxing the scope I happened to point the objective end downward and the dust cap just fell off. And most frustratingly, while I was packing the scope up at the end of the day my hand hit the dust cap and it bent in and left a smudge on the objective lens. Grrrrr. I have a cheap Meade spotting scope from back when and it has spring-loaded dust cap that locks in place, like the dust caps on most DSLR cameras and lenses. If the dust cap on the Spektar was at least hard plastic, I could shim it with felt (I’ve done this with countless telescope dust caps). Feels like they really cheaped out here.
- The padded view-through case is nice but it leaves the focus knob exposed. In my book that’s okay for day use but not for something you’re going to store the scope in. If there’s one place you don’t want moisture or dust getting inside the case, it’s at the focus mechanism. Something like a velcro flap over the focus knob would be easy enough to install, but it feels like something that should have been addressed at the design end. Maybe it’s mean to pick on this one thing – I buy scopes all the time that come in padded boxes with no case, so the padded case here is definitely a step up. The Telescope Warehouse on eBay sells locking and waterproof cases that fit spotting scopes – I’ll probably be picking one up shortly.
Verdict? The scope has some quirks and some outright deficits. Fortunately they are with the mechanics and accessories rather than the optics. It also has some very nice features that make it easier and more convenient to use, compared with most spotters I’ve used in the past. At the list price of $130 it’s probably possible to do at least as well or better with something from Alpen, Barska, Bushnell, or Celestron. But for $40 it’s a steal.
The rest of the photos are quick digiscoping pix from this afternoon’s test run. It was overcast, I didn’t get outside until just before sunset, and I didn’t put on the camera adapter but instead shot everything handheld. So some of the problems with the photos are not the fault of the scope – the low light levels meant low contrast, uneven field illumination was mostly my inability to get the iPhone’s camera lens centered in the spotting scope’s exit pupil, most of the CA and almost all of the spherical aberration are from the iPhone, and I couldn’t hold the camera as still as the adapter so the detail in the photos does not nearly match the view through the eyepiece. I need to get out and play with the scope under better conditions, but for now, this is what I have. Other than the unmagnified reference image, none of these are processed at all, partly for versimilitude and partly because I’m lazy.
With all of those caveats in mind, here we go. Captions are below photos.
Here’s an unmagnified iPhone pic of the utility pole and the mountain shown in the close-ups below. The utility pole is about 300 feet away, the mountaintop is 10.5 miles according to Google Earth.
Utility pole at 15x. Darkening around the outside is me not getting the camera in the right spot – it was not visible visually. See the woodpecker?
Utility pole at 45x. Woodpecker had moved on by this point. I could see a lot more detail visually, including growth rings in the wood and the twisted wires that make up the power lines.
Those trees on the ridgeline admittedly do not look brilliant. But considering that they’re 10.5 miles away and being imaged handheld through a couple of intermediate layers of branches, I’m pretty impressed. We’re in the glidepath for airliners going to LAX and Ontario, and for small private planes out of Cable Airport, and I had fun this afternoon chasing airplanes with this scope. The next clear night, I’ll probably be out chasing satellites instead.
As of right now (early in the morning of December 9, 2015) the spotting scope is still available at $39.99 with free ground shipping. Optical Instruments has a bunch of other stuff on sale right now, including some binoculars and small telescopes. If you’re interested enough to get this far, you owe it to yourself to give ’em a look.
