Review: Explore Scientific 16”, Europe edition, late 2016
Nov 12 2016  I have been considering buying or making a 16 incher for a while now. Mirrors only (if you wanted to make your own scope) cost at least 1200€ to 1400€ (Hubble optics or GSO, not counting import duties and shipping cost). So, when I learned that Explore Scientific had a European sales on their Ultra Light series, placing the 16” at 1698€, I jumped on it!

Telescope Making for the Relatively Unskilled
Dec 03 2016  I’ve received several private messages from a few people on CN who have seen some pictures I’ve posted of the telescope I made, which is also my icon picture, and asked if I had a build thread. I didn’t. But all along I had an idea of writing this article because while I have seen many pictures and build threads of outstanding scopes built by people who are obviously either machinists, carpenters or engineers or just very experienced builders with a full suite of shop tools, I am none of those and I only have a couple of hand tools and minimal skills & experience. But I built this thing and it’s outstanding, so I figure that maybe there are folks out in the world who would like give telescope making a try but might be a little intimidated by some of the beautiful work displayed, especially on the DIY forum. This is NOT another “How to Build a Telescope” article. Rather, it’s more of an idea on why I built what I did, some of the planning and thought processes involved and how to get around the lack of tools or skills. (Hint – subcontract the hard stuff.)

Cosmic Challenge: Globular Clusters in the Fornax Dwarf Galaxy
Dec 03 2016  Let's begin this challenge with a riddle. What's big and round, close at hand, and yet nearly impossible to see? If you answered "the Fornax Dwarf Galaxy," then you are correct! The Fornax Dwarf, a dwarf spheroidal system, covers a 17'x13' area of our late autumn sky and lies about 530,000 light years from the Milky Way. That's well within the confines of our Local Group of galaxies. And with a magnitude rating of 9.3, it sounds like it should be bright and easy to see. But when we look its way, it's not there. Even the best photos manage to record only an incredibly dim, elliptical haze peppered by some 19th-magnitude stars!
