So I got the case out and laid the new Evolution mount with 8” telescope attached into the foam case. On each side of the old 8se carrying case I used a black felt pen to outline what I would have to cut out for it the new mount to fit.

Sometimes I like to find a way to use old things in new ways. Awhile back when I bought a Celestron 8se, I also purchased a nice foam carrying case for the combined mount and telescope. As I was trying to figure out how I might transport my new Evolution mount with my Celestron 8” telescope, I remembered the 8se foam carrying case and wondered if I could adapt it for a new use. So I got the case out and laid the new Evolution mount with 8” telescope attached into the foam case. On each side of the old 8se carrying case I used a black felt pen to outline what I would have to cut out for it the new mount to fit. Then I got my trusty Kobalt cutting knife out and began cutting out small segments of foam from the right side that I could then remove by hand. I was careful to try to “stay within the lines”, and the right side looked OK when done. I then proceeded to tackle the left side. When finished I placed the Evolution mount with the 8” telescope attached into the left side and it was a nice snug fit! I was then able to close it and zip it up, ready for carrying wherever I might want to go!

I highly recommend using a Bahtinov Focus mask to assist focusing your video astronomy setup. It is a very inexpensive way to take the guesswork out of focusing. Slew to a fairly bright star and get it fairly close to focus. Then place the Bahtinov Focus mask on your telescope to produce interference lines that aid in focusing. Continue to adjust the focus until the center line is evenly spaced between the other two lines. I have discovered that your exposure time or gain is important to getting the best possible focus. You can start with a fairly bright image to center the middle line. To get an even better focus, reduce the gain or exposure time to where you just see the lines. You may find that you were not as close to focus as you thought. Here is what the above image changed to after reducing the gain, showing that the focus can still be improved slightly After a little more adjusting, you will see a very nicely focused image. Now remove the Bahtinov Focus mask and you are ready for viewing. You can later quickly recheck the focus during the evening by slewing to a nearby bright star. Place the Bahtinov Focus mask on your telescope again to see if any slight focus adjustments are needed. |
AuthorAstronomy was my favorite hobby many years ago, but was gradually set aside due to work, family and life in general. In recent years I resumed my hobby looking forward to using the new technology that is now available. Then I discovered Video Astronomy. Then I learned how to do it Remotely. I wrote some books, and decided to set up this web site to continue to pass on what I learn. Categories
