Of the more than 130 globular clusters gravitationally linked to our Milky Way galaxy, only four are known to contain planetary nebulae. The best known example of a planetary/globular pairing is Pease 1 found within M15 in Pegasus. That's this month's Cosmic Challenge.
When doing astrophotography, most of us use a laptop for camera control, autoguiding and image display. At public outreach stargazes we often just want to take a single time exposure in order to show visitors what 'that fuzzy blob' they see in the eyepiece really looks like, it's often not at all convenient to set up a laptop. A tablet is an excellent tool for image display, but there's still the problem of a USB cable from the tablet to the camera. Many tablets don't even have a full size USB connection or require a special adapter or cable, but they all have WiFi. That's great if you're using a camera that has WiFi capability but what about those DSLRs that don't? Enter the TP-Link MR3040 Wireless Router.
Sometimes, aperture fever can lead to a severe case of brain damage. The kind that compels you to make a purchase that by all acceptable standards would be considered insane. Such is the case for those who decide to buy a gigantic binoscope. Already much has been said about the huge disadvantages of the binodobson. After all, there must be a reason why almost no telescope manufacturing company offers them. But are these prejudices true or are they merely based on assumptions without any real experience to back them up? In order to find out, me and my friends of the astronomical society of Trentino in northern Italy have put my new 18” binodobson to the test.
This scope has been reviewed at great length in a comprehensive essay by William Paolini (http://www.cloudynights.com/page/articles/cat/user-reviews/first-impressions-of-the-lunt-152mm-f8-ed-apo-r2889), and I strongly recommend that prospective buyers study his excellent article. I will not repeat what he said except to emphasize that the scope has great optics, and nice fit and finish. It gives razor sharp views with no hint of false color. Definitely this is a great scope for visual or photographic purposes! Using this scope is fairly intuitive for anyone familiar with common telescopes. Unfortunately the scope does not come with any sort of manual, so there are a few items that may not be obvious when you take delivery of it. Here I wish to bring up two matters that may be of interest to prospective buyers.

More than four decades ago I happened upon dark skies quite by accident while on a cross country trip with my good friend Mike. The memory of that experience that has remained all these years is how the common Messier Objects and other DSO were all apparent with the naked eye, looking like bright fuzzy patches against the dark sky. Since then, my observing has primarily been only from suburban sites where the Milky Way is only rarely detectable. Today, I like many others, wonder what it would be like to observe at a truly dark site. We also wonder about what equipment we should take, whether it would be a waste to take such a trip and not acquire and bring the largest aperture telescope possible, and of course we wonder just how different the celestial objects we observe will appear at these darker skies.
Last month, I offered up two planetary nebulae for smaller apertures. This month, we again hunt for a pair of planetaries. This time, however, we may need a little more oomph to get the job done.

Here's a two'fer for you, a pair of challenges found within 1° of each other in the constellation Aquila the Eagle. Both of these planetary nebulae present interesting tests for smaller apertures, each in its own way.
