Scattered Thoughts . . .

I made two solar filters relatively recently.  One was made a little over a year ago (pictured at right) and the other was made a little over two years ago (next picture, below).  I was happy with these two filters but rarely used them because I have far better types of solar filters to use.  I think my primary reason for this exercise in making these filters was simply for the experience more than any other reason although there were a couple of other reasons (which I'll address below).  But let me start this blog entry by saying that I will never again use one of these piece-of-garbage, flimsy, and consequently, dangerous Baader film solar filters! I haven't used either filter more than three or four times each in this two year period and they have been handled exceptionally carefully ( never touching the filter material) and stored in protective zip-lock bags and these bags placed inside protective boxes for storage until the next use.  Even though these two filters were

Back a year or so ago, I built a wood frame solar filter for one of my larger telescopes and, if interested, you can  read about it here.   This is another blog entry about a new homemade solar filter that I made about a month ago to be used, mostly, for testing purposes but it never hurts to have multiple ways to view the sky, daytime or nighttime.   I decided to build this solar filter for two reasons.... 1) I already had the supplies so it wouldn't cost me anything, and, 2) I want to compare one of my Spectrum glass solar filters to this new solar film filter I made as well as compare it to my solar wedge as a comparison between the three types of solar filters.   To make this comparison as accurate as possible and to keep as many scientific controls as possible in this little test, I decided that I should use the same telescope and the same camera so the only significant variable in this test would be the filter itself.  My small Skywatcher ED 72mm refractor was the best option

My health is still recovering from the problems I had Saturday but I felt like dragging a telescope out to the front deck to observe the sun this morning. It doesn't require a whole lot of energy to peer through a telescope but I do need to be careful out in the sun or I'll end up with failing health again. I definitely don't have the energy nor is my head clear enough to attempt any home improvement/repair projects so I will probably bounce between the piano and the telescope all morning. It is a bit hazy again today so the viewing isn't great but it is better than the clouds and rain we've had for the past week or longer. At least the sun is shining! Up until today, all my astrophotography has been done using my Sony a6000 with its 1.5x crop sensor. This morning, however, I decided to give my full frame Sony a7 a shot... My Sony a7 worked just fine. This camera will give me a slightly wider view but also should provide smoother gradients and simply bette

I've been waiting for the past week for another good day to observe the sun so I could try my hand at solar astrophotography yet again. This morning was finally a good morning to set up my telescope on the deck so I started moving gear to the deck early this morning. While waiting for two new solar filters to arrive and for the weather to be more suitable for astronomy, I've been doing a lot of research about our sun. I actually learned quite bit... some of it even a bit frightening... but I'll save that info for another blog entry which will be written solely for that particular topic. Last week, when I tried my initial attempt at solar astrophotography, I was left feeling a bit disappointed and later found that adding two additional filters to my telescope would allow me to capture more detail. Unfortunately, I'm still waiting on one of these filters to arrive but I did have one of the filters to use this morning. So, if I could see just a little bit more detai

The sun can be seen illuminating the back end of the Wedge. It has been difficult for me to get out at night lately to view the night sky with a telescope. We don't get crisp, clear nights all that often and especially in the summer. My health problems don't help in this cause either because quite often I am left too exhausted by the time we finish dinner. The real icing on the cake lately has been a roaming bear in our neighborhood at night and I really have no desire to bump into a roaming bear in the dark! Needless to say, it has been difficult to get out at night for some astronomy in recent weeks. The aforementioned nighttime viewing problems got me wondering about giving daytime solar astronomy a try. To make a long story short, I found that all I need to do to view the sun is replace one part of my telescope with a part that is designed specifically for viewing the sun... then add a filter or two... then I can view the sun with my own telescope and shoot images w

My health has been rather lousy lately so today is another "down day" of inactivity while my health recovers.  I've been rather frustrated and anxious lately about accomplishing nothing around the house to the point that my doctors are a bit concerned because they feel that I am having some heart issues. I'm convinced it is just frustration and a bit of anxiety causing these relatively minor heart issues. Unfortunately, the more I have to sit around recovering, the more frustrated and anxious I get. There is a lot I want to do and accomplish but my health is refusing to cooperate. And, to be honest, we've been spending far too much time at the hospital and medical appointments. I'm frustrated. So, as I sit here again while my health recovers, I've decided to revisit the moon images from the other night.  I shot this series of images in two formats... a compressed jpeg format for simplicity and a RAW format for more detail. I always shoot both jpegs a

The eyepieces I had ordered last week for our little cheap telescope for the kids to use arrived yesterday afternoon... finally! These are relatively low-cost eyepieces but far better than the cheap, useless Celestron eyepieces that came with this telescope.  Since the moon was still in the sky this morning (again), I tested these new eyepieces by viewing the moon. These eyepieces looked great and are a tremendous step up from the original Celestron eyepieces so this was a good, low cost solution. They are not as good as my larger Baader Hyperion eyepieces but they are just fine for this cheap little telescope. The view of the moon this morning was quite nice. The three smaller eyepieces to the right, below... Orion Expanse eyepieces... are the eyepieces to be used with this small scope. The larger Baader Hyperion eyepieces to the left are for my better telescope and are quite good! I'm now looking forward to some clear night skies!
