ASTRONOMY

WITH A SMALL TELESCOPE

 

The images on this page are simulations (and photographs) of my observations using small telescopes.  The type of telescope used is noted in the upper right corner of each image.  Where you see 114mm the telescope was a Celestron 114mm Newtonian Reflector with a focal length of 910mm and a focal ratio of f/7.  254mm indicates that an Orion XT10 254mm Newtonian Reflector with a focal length of 1200mm and a focal ratio of f/4.7 was used for that observation.

Below the note on which telescope was used you will see a number that indicates what eyepiece was used.  In some cases I did not keep a record of what eyepiece I used, in such a case no number will be listed below the telescope.  All eyepieces are Orion Highlight Plossls.  At present I am using the following eyepieces: 7.5mm, 10mm, 17mm, 25mm and 32mm.  Where you see a "B" after the eyepiece you will know that I have used that eyepiece with a 2x Barlow lense.
