Here is a link to an image of Jupiter taken by an amateur in Australia that happened to have excellent seeing when he took the image. It is at www.spaceweather.com The link to the actual image is at http://www.acquerra.com.au/astro/gallery/jupiter/20100830-173830/large.jpg -Fred

Here is a Kodachrome 64 slide of the Moon taken at the prime focus of my Cave 6-inch f/15 refractor. Image was taken in Deember of 1995. The focus is slightly off and the other issue with the Canon A1 camera is the vibration that the shutter induces when it is tripped. In another image, using eyepiece projection, the shaking is noticable. I attempted to focus are carefully as I could, as I did not have any aids to help me.

Big Bear Solar Observatory (BBSO)
Fred Ley απάντησε στην συζήτηση του/της PapGeo σε Παρατήρηση Ηλίου
Hi Papgeo, Yes, it certainly is wonderful that they have installed a new instrument at the observatory. The old equipment was hauled off to make way for the new items. In case you might be interested in viewing the older telescope, go to this link on my site to see a few images that I took. I guess when I go bac home I will have to run up to the lake and see the new telescope. Here is the link... http://www.instrumentsoflight.com/bigbear.html When I saw the image of the sunspot on spaceweather yesterday, I was amazed at the resolution of the image. Can't wait to see new images from the instrument. -Fred -

In the above image, there is a long arm that extends downward to the base and has a weight attached to the end. I must conclude that it plays a role in allowing the observer to balance the setup. I didn't meet the owner at the time in order to ask any technical questions. This chair reminds me of Wayne Schmidt, in our local club, who built a chair of this sorts, and mounted two 8-inch Newtonians on it in order to have a "binocular" view of the heavens.

Hi Ourania, The book by Woodbury is a good read, but the the book by Florence is a very in-depth view of the construction of the 200-inch Hale telescope and also has a very nice bibliography. Below is another book about Palomar that I forgot that I had. "Palomar" written by Helen Wright, who also wrote the biography of George E. Hale. It was printed in 1952. The book titled "Ten Years Work On A Mountain Observatory" by George Hale, describes his work at Mt. Wilson Observatory. "Signals To The Stars" by George Hale is one of four books that George Hale wrote. The other three titles are... The Depths Of The Universe The New Heavens Betyond the Milky Way (I don't have this one yet) These were printed in the 1920's. The biography of one other important person is Russel W. Porter. He is regarded as the "father" oof amateur astronomy in the United States. there is a nice read at Wikipedia if interested located at this link http://en.wikipedia.org/wiki/Russell_Porter The other book that I need to purchase is "Journeyman Machinist." The author seems to have have had an interesting career in the field of astronomy. My apoogies for giving you all this information. I don't know your level of interest pertaining to Palomar Observatory. There was even a postage stamp issued in 1949 to cemmemorate the observatory. Clear Skies, -Fred -

Hi Ourania, If you enjoyed the video on Mt. Palomar, you may enjoy these two books about Palomar too. They are out of print, but they can be acquired in a used condition. -Fred -

Trailer Mounted Observatory 2
Ο Fred Ley σχολίασε σε Fred Ley για αστροφωτογραφία Τηλεσκόπια και Εξοπλισμός
The trailer does have leveling stands on its four corners which should work just fine. I would conclude that if one were in there taking a time exposure, slow movement would be advised as recordeing devices are so sensitive to vibrations. I have a few more images of this observatory, but just decided to place a few on the site. -
