Double Cluster   2 comments

Went up on the roof after midnight Sunday night:  crystal clear skies.  Looked around with a pair of  7×35 binoculars.  Could count nine stars in the Pleiades.  With my voyager (f4.4, 114mm aperture, 500mm focal length. ball mount), more than forty stars.  Tried to find M31, scanning around, no luck.  I always start at Cassiopeia, and after giving up, scanned down from there.  Bang! the double cluster!  It looks great at 19 power, with a 2 degree field.  Moved still lower, ran into M34.  A very good night.

Jupiter, shot at f/15, enlarged 200%.  Color removed, but there wasn’t much to begin with.  Logitech fusion camera, 640×480, 1900 frames acquired, 1300 stacked.    There may be more info in the clip, but this is about the best I’ve done with the planet.


Here is the same video clip but stacked at 95% instead of 80%, 311 frames instead of 1300.

19 Power, Rich Field   Leave a comment

Iphone through the Ipiece.

Bushnell Voyager 500mm focal length f/4.4 telescope.  With a 26mm Meade 4000 Super Plossel, I get 19 power and over four full moons width in the eyepiece.  After years of cogitating over adding a finder to the telescope, I discovered a built-in finder:  removing the eyepiece and you get a one-power skyview with a big black disk for a target.  The disk is the secondary.  Move the telescope until the bright object (Jupiter, Sirius, Vega all worked fine) slips behind the disk.  You can see it going in and going out, so it is easy enough to guess center.  When the object is in the field of view, the shaft of the focuser will light up.  Slip in the eyepiece and the object is in the field of view and usually focused.   Jupiter is now easy to acquire.

Last night I found the Hercules cluster pretty quickly this way, centering Vega and starhopping to Hercules.
