Scattered Thoughts . . .

W hen I was out testing a new solar astronomy gear configuration a few days ago, I had a problem with my focuser slipping.  This was caused by two factors...  first, this new configuration put a lot of weight on the focuser...  and second, at the time, I was viewing the sun at its highest point in the sky at noon.  This orientation made it easier for the focuser to slip downward toward the ground.   When I brought the gear back indoors, I tried to adjust some of the setscrews underneath the focuser but, honestly, I had no idea what any of the setscrews did.  You would think that you want all of them as tight as possible but that is completely wrong in this case.  I had to do some research. While in bed that night, I did some research on my Kindle.  I found a thread in an astronomy forum about adjusting this focuser.  I wanted to get out of bed right away to fix this focuser but I wisely memorized the page and then went to sleep instead.   The next evening I pulled out this little teles

I 'm still feeling rather lousy and coughing whenever I move so I'm laying low at home.  This morning, however, I accomplished a few small maintenance tasks on my astronomy gear.   First, I wanted to install a better saddle on my newly converted EXOS2 manual mount (photo at right).  I don't care for saddles with a single bolt holding my telescope on the mount.  I prefer two pressure clamps holding my telescopes.  I had ordered an appropriate saddle a few weeks ago and it arrived this past week.  I just needed to drill a hole and then assemble it so that was a small and easy task that proved to be unremarkable.  Then I moved to my best telescope.  My Explore Scientific 102mm APO refractor recently developed a sticky focuser.  It wasn't sticking to a complete stop but it was not as smooth as I like it.  Any bit of stickiness in the focuser causes some vibration in your view so I new I wanted to resolve this little problem before I got worse.  This task was a little more i

I recently picked up a relatively inexpensive larger telescope to help improve my views of the sun.  I say "relatively inexpensive" because a little, cheap camera lens would cost more than this telescope cost.  This new telescope is significantly larger than my previous "large" telescope which should help to see more detail on the surface of the sun...  when and if the skies here ever allow for crisper viewing! Although this telescope is larger, the optical glass in the telescope is not nearly as good as the glass in my other telescopes.  For relatively narrowband viewing of the sun, however, this should not matter.  Since the glass in this telescope isn't "perfect" (to simplify things), it is considered more of a low-end telescope.   When this telescope arrived, I needed to replace the stock focuser.  Most low-end telescopes only come with a single speed focuser, however, it is far easier to focus fine detail when you have a dual speed focuser.

I've mentioned in a previous blog entry that I've been working on getting some telescopes ready for nighttime viewing in the warmer weather. The grandkids are getting old enough to enjoy viewing the night sky so this gave me a good reason to play with some telescopes. I have a background in aerospace so this has always been an interest of mine but it is always nice to have another reason like grandkids. It makes it easier to justify the hobby. Naturally, it seems it has done nothing but rain (and snow) for all but one day since I assembled these telescopes in our living room a few weeks ago but this has given me time to decide what to do with one or two scopes that have been terribly frustrating to use. One of these telescopes in question was a Celestron   AstroMaster  114EQ reflector telescope. This telescope has been nothing but frustration since we bought it quite a few years ago. Nothing looked even halfway decent through this scope. I've collimated it (aligned the
