H-Alpha Solar Sketch Move mouse over sketch above to view labelsClick image for larger version. Observation Notes: The latest active region looks fantastic. At 40X, I counted 10 spots/pores amid a network of plages. There were 3 prominent spots in the active region and a close pair on the...
Sketch of Epsilon Monocerotis (Struve 900)Click image to view larger version. Observation Notes: Epsilon Monocerotis resides in a populous star field. Color was subtle, and it seemed that the A8 primary was pale yellow while the F5 secondary appeared steel blue-gray. Other observers see the colors as follows: Smythe: Golden...
For every few successful observations, there have to be some failures right? I got up at 3:30 AM to set things up and then watch for any evidence of the LCROSS impact in Cabeus Crater at the lunar south pole (scheduled for 4:31 AM Arizona time). I set the 8...
If you thought new double star observations and sketches were getting pretty skimpy around here, you'd be right. It looks like I went through most of 2009 with only one double star sketch added. The reason is that I've been trying to work on a new process for my digital...
Sketch of Rigel (Beta Orionis / Struve 668)Click image to view larger version. Observation Notes: Rigel really makes a beautiful pair. The effect of the brilliant primary glaring across its subdued companion is striking. The secondary does hold its own though, and even though the diffraction spikes cut straight across...
Sketch of Bullialdus and SurroundingsMove mouse over sketch to see labels. Click image for larger version. Observation Notes: The seeing was horrible on the night of this observation and I had to keep the magnification to 120X and observe wider fields. There was some very nice terrain to view...
Sketch of Messier 89 (NGC 4552)Click image to view larger version. Observation Notes: Elliptical galaxy, Messier 89 was a simple visual object: small, circular, about 2 arc minutes in diameter with a stellar appearing core. A double star punctuated the view about 8 arc minutes to the northeast. Sketch/DSS Photo...
Observation Notes: I made this follow up observation of the blue snowball to get a more detailed look at structure for the October 2009 issue of Astronomy Now. The inner and outer shells possessed a soft, pentagonal shape. The inner shell was annular and had brighter condensations to the...
The October issue of Astronomy Now focuses on NGC 7662, the Blue Snowball nebula. Two methods are covered in this column: 1) Using an isophote (contour) field sketch as a basis for a final shaded drawing, and 2) using Photoshop to add subtle color to the scanned drawing. Subject:NGC 7662...
