Messier Observer’s Planisphere by Celestial Teapot Designs

Looking for a unique planisphere that includes the Messier objects and a suggested order to view them for a marathon? How about a locator chart for challenging identification areas like the galaxies in Virgo? You might want to check out the KickStarter link below. It’s the Messier Observer’s Planisphere by Celestial Teapot Designs that friends of ours developed. I’m looking forward to getting my hands on one!

2012 05 17 – Prominence sequence

•April 5, 2015 • Leave a Comment

May 17, 2012, 13:35 UT – 18:41 UT

This interesting prominence doubled in size and then finally broke free of the limb. The time sequence spanned over 5 hours.

Northeast prominence at 30-degree position angle. Internally double-stacked Coronado Maxscope 60mm H-alpha telescope 400mm focal length, LXD75, Baader Planetarium Hyperion 8-24mm Mark III set at 8mm, 50x magnification.

Sketched with white Conté crayon and pastel pencil, white Prang color pencil, and black Strathmore Artagain paper.

2014 Oct 14-30, Daily Sunspot Tracking

•February 19, 2015 • Leave a Comment

It’s been several months, but I finally had the opportunity to process and animate a 17-day daily sunspot tracking sequence from October. It features AR2192, the beautiful large active region that caused a stir that cycle.


Oct 14 - 18

Oct 14 – 18


Equipment used
Celestron 102mm f/9.8 refractor, 7-24mm Hyperion zoom set at 16mm, 63x, Thousand Oaks white light filter, homemade Sun funnel for initial sunspot placements, LXD75.

Sketch media
White card stock, superfine black felt-tipped artist pen, 0.5mm mechanical pencil, processed in Photoshop and orientated so that north is up, west is right.

2011 09 11 – ISS Lunar Transit

•September 11, 2014 • Leave a Comment

I drove to Leander, TX, this morning to catch the ISS lunar transit. This is the field sketch, mirrored and rotated to match standard orientation.

20140911 ISS lunar transit

Equipment: 102mm f/9.8 refractor on an LXD75, 16mm eyepiece, 13% transmission Moon filter; Sketch media: black Strathmore Artagain paper, white pastels, white charcoal, black charcoal

The sketch was a quickie compared to the phase sketches I typically do, but I wanted to ensure the ISS wouldn’t be lost in the detail. The ISS crossed the lunar face in less than half a second, starting near the craters Steinheil and Watt. It then passed near Encke before crossing the NW limb.

I re-familiarized myself with the guidelines from Alan Strauss’ ISS solar transit observation in 2011. You can view the report and sketch on his site, Lost Pleiad Observatory.

Before leaving the house, I rechecked the ISS flight path and its central line for passing in front of the Moon. CalSky is a great program for this. On my iPhone, I used GoSatWatch and set alerts for 5 minutes before the pass and another for when the pass began.

The sketch was started almost an hour before the pass. So that the ISS wouldn’t be lost within the abundance of lunar terrain, the majority of detail was omitted from the sketch. Once the first alert went off, I stopped sketching and prepared myself for the pass. My observing partner, Freckles (my dog), was put back in the CRV so that I could focus solely on the view. The transit would last only a fraction of a second and in that time, I wanted to note: where it entered, the flight path, and where it excited; color and luminance; shape, size and orientation; and viewable panels and modules.

The second alert sounded and within moments, the ISS made its transit. I was surprised to see that it was a glowing white color (expected a silhouette) and what appeared to be a shadow on one side of it. It seems I may have caught a module and one of the solar arrays. The shadow was most likely another solar array or the shadowed area of the module. As for the orientation, it was offset a little from its path, but things happened so suddenly that I’m not certain I’ve recorded it accurately. My focus was more on the overall shape and the shadow of the ISS.

With each ISS pass, it’s an ongoing endeavor to improve my observing and sketching skills for the next time!

This long-period comet was an easy spot in the constellation Cassiopeia at 10.7 magnitude. The coma was bright and dense. Its outer edges were diffuse and there appeared to be a very faint elongation to the SSE.

It’s always a treat to follow the International Space Station (ISS) through an eyepiece. During a recent outreach event, I even had a line of visitors taking quick turns at the eyepiece while I tracked the pass for the them using the Dob with a Telrad.

During the past few days, my husband and I made a joint efforts to image the International Space station, his by webcam using the 10-inch LX200 with manual tracking and mine through sketches using the 16-inch Dobsonian and a 13mm Ethos. This telescope/eyepiece combination makes it fairly easy to track the ISS while providing a bit of umph for details.

There were two ISS passes on the night of August 23. I used the first one for practice and, from that, determined that a voice recorder was definitely needed for the 2nd run at 21:43-21:46 local time (Aug 24th 02:43-02:46 UT). Directly after the observation, I made a rough field sketch and jotted down notes. A more-detailed, color sketch was completed inside using my notes, voice recording and the field sketch for reference. When the sketch was complete, it was scanned and processed in Photoshop CS6 to better represent the luminosity of the view.

The solar arrays were outlined in bright burnt yellow with deeper burnt orange running through the center of them lengthwise. The module was bright and long on the following end. More details were visible during moments of clarity with smooth tracking, but I failed to describe the view with enough depth to transpose them onto paper. I was able to add what appeared to be the thermal control radiators near the truss on either side of the module as well as a section of the module that runs parallel to the truss on the leading edge.

Equipment: 16-inch f/4.5 reflector on a non-tracking Dobsonian mount, Telrad, 13mm Ethos

Application for passes: GoSatWatch – Satellite Tracking for iPhone

Sketch media: black Strathmore Artagain paper, color pencils, white gel pen, color Conte’ pastels, blending stump and then processed digitally in Photoshop CS6
