Today is my last OpticsBlog, thanks to my long-awaited retirement or, I should say, full retirement, as these blogs were a source of part-time income, these last few years.

Using small telescopes of 60 mm to 90 mm in aperture (diameter of the telescope lens or main mirror) is fun. Larger telescopes have their place, of course, but some of us diehard astronomers tend to forget how enjoyable it is to grab a small telescope, now and then, for the sake of simplicity, or convenience, or ease of use or, heck, just to do something different. For darn sure, my small telescopes do not collect dust.

The moon is tailor made for viewing in small telescopes, since the moon is such a bright object and image brightness is where …

The skies have been clear, this week, so I’ve gotten some good observing time with the astronomy binoculars and telescopes. I could still use another clear night or two for the sake of using all my telescopes and binoculars…

I like old guns and I also like the old rifle scopes that went on those old guns, especially those old Weaver rifle scopes that were made in El Paso, Texas, sometimes known as El Paso Weavers, to distinguish them from newer Weaver riflescopes, since Weaver, like so many rifle scope companies, was bought and sold a number of times, over the years, and eventually went to overseas production. New Weaver rifle scopes are still available, by the way, and they’re even better, optically, than the old Weavers, but they are no longer made in the good old U.S of …

You’ll never see telescopes rated as to their “comfort”…

I’m about to the point of needing to buy a digital camera. I have to say, I dread buying digital cameras, but the way I use small digital cameras – outdoor photography, some astrophotography and a whole lot of…

When you’ve used an optically excellent spotting scopes or, for that matter, optically excellent rifle scopes, telescopes, binoculars or optically excellent anything, it really does spoil you. It makes it very hard to go back to just average optics, even though “average optics”…

How does your telescope rate in terms of quality and, especially, as far as optics?

Chances are, it is more than good enough and, perhaps, as with any of my telescopes, it rates as truly excellent. Fact is, unless you have been spoiled (as I have) by great optics or unless you have bought something at the absolute bottom of the telescope market, your telescope probably delivers anything you want within its optical powers to grant when you look through the telescope eyepiece. Today’s mass produced telescopes, thanks to computerized production, offer consistently usable optics across the board. Pick from …

Finally, after years of wanting a parallelogram mount for my astronomy binoculars, I found a used one and it’s on its way in the mail. It’s a mount I should have bought years, ago, but just never made it a priority, probably because I kept using standard photo tripods to get by when I needed to use tripodswith my binoculars. Photo tripods will work for astronomy binoculars, of course, and I already had some for use with my spotting scopes and digital cameras, so I was in no hurry to buy a tripod specifically for use with my astronomy binoculars. …

When I first started in astronomy, oh so many years, ago, I used to read accounts written by other astronomers of objects they could see in the telescope eyepiece. It was all very mysterious and fascinating, of course, and made me all the more eager to buy a telescope and see what I could see.

Didn’t take long and I had my own little refractor telescope to do just that. Only problem was, I wasn’t sure what to expect. Was my little telescope big enough to see some of those objects other astronomers were seeing? Would I recognize these objects …
