Broken Strap On My Carry-on Case For My Refractor

Wouldn't you know it. We are moving next week and have to jump on a plane (actually three planes and 16 hours of travel, ugh). So my lovely Stellarvue CN7 carrying case which I use to lug my 91mm BO refractor around in along with my eypieces, diag, etc., decides to have the strap break. I mean the whole buckle assembly.

I used to have a nice strong strap from a laptop case around, but I'll be damned if I can find it. Now I have to run around and try and find a solution or I will be humping it around with the case in one hand, while pulling my laptop case behind me. Look ma, no hands. What timing!

What is a Planisphere?

What is a planisphere and do I need one. A planisphere is simply a tool we use to find our way around the sky. It consists of 2 circles, one has a sky map printed on it, the second has a window cut into it which allows only the part of the sky visible in the sky at the intended point in time to be seen. The masked circle is marked off in a 24 hour clock configuration, while the sky map portion is marked of in the 12 months of the year, subdivided by day.

To see what is in the sky on the day and time you want to observe at simply line up the day and time and the sky chart will display the objects that are visible. Simple, easy to carry, and very efficient. I used one when I was starting out, and still use one to this day. A planisphere is especially handy for quick, grab and go sessions or binocular observing.

Orion makes a beauty that I can highly recommend: Orion Star Target Planisphere
