Quick View of the Moon Tonight

T he moon was shining brightly through our living room window as we headed to the bedroom so I figured I would take a quick view through that new little Orion 102mm Mak-Cassegrain telescope I evaluated recently.   Sheila was in the bathroom getting ready for bed so I had a few minutes to kill.  I went to retrieve a lightweight mount and the telescope and set it up at the window to take a quick look...  I easily found the bright moon in the sky and saw nothing but out-of-focus mush.  I again repeated what I had been saying all along about this little Mak-Cass telescope...  "what a piece of junk." This prompted me to go retrieve my Skywatcher 72mm refractor which is equally as small but with a much short focal length.  I brought that out to the living room and I was immediately treated to a stunningly sharp view of the moon.   Viewing through a window with optics is a no-no because glass will cause all sorts of problems.  Heat escaping the house through an open window is often

Casual Evaluation of a Beginner Telescope

Introduction T his blog entry is a little different than my usual entries.  Then again, my thoughts are often a bit scattered so there isn't really a consistent theme to this blog.  I do sometimes write about my hobbies including astronomy but this blog entry is not one of my typical short blog entries about viewing this or that or about some small astronomy project.  This is more along the lines of a casual review of my thoughts about a telescope.  If you are more interested in some astrophotography images rather than read about a boring telescope evaluation, then just scroll down to the closing of this blog entry (about halfway down this page). Quite often, people who are wanting to get involved in backyard astronomy for the first time ask other astronomers which telescope would be best to purchase as their first telescope.  This is a very common question that is asked at least once a day.  As a result, I find myself trying to provide advice to astronomy beginners a few times eac

New Look for Old Telescope

I 'm still mending a sprained MCL in my right knee so I'm still not really accomplishing much on my To-Do list.  Every now and then, however, I feel halfway decent and am able to jump into a small little project at the kitchen table.  This still needs to be short because I need to keep changing positions...  no sitting for a long period of time, no standing for a long period of time.  This keeps the size of these occasional projects on the very small side.  Plus, the longer I work on any project, the more likely I am to do something stupid with my knee.  The last thing I want at this point is to be set back to square one yet again.   I have this old Celestron 70mm refractor telescope that, in recent years, I adapted to a different type of mount.  In order to do that upgrade, I needed to remove a bunch of mounting hardware that was bolted through the optical tube.  This hardware wasn't needed and was in the way of the new mounting cradle rings and dovetail bar so most of the
