Maybe not autoguide!

It’s been many years since I first celebrated being able to autoguide while exposing astrophotos on my CCD camera. (Finally autoguiding from 2009.)

Now with new techniques and software available, I might be able to abandon autoguiding.

The current software and hardware stack for astrophotography is so vastly different and better than what I had to work with […]

Many firsts at GMARS

Observing report, February 23, 2020

This would be my first night observing from a powered telescope pad at GMARS, Riverside Astronomical Society’s Goat Mountain Astronomical Research Station, in Landers, CA. It was a beautifully clear but cold February Sunday evening. It was also the first real observing night for a new mount, plus a new and unfamiliar […]

Working with a broken astronomy camera

Last year, I had some really bad luck with astrophotography.

I replaced my old laptop (Dell, Windows XP) and installed a new suite of tools to replace the somewhat ancient and unsupported camera software. At one point during my first “shakeout” evening (October 2014), the new software started spinning my telescope around the declination axis. It made […]

April Observing: Supernova and a Comet

The weather forecast for our favorite spot, Amboy Crater, called for decent conditions but high winds. (Why do we care about the wind? Here are four reasons I can think of: simple comfort, blowing charts and equipment, maintaining a target in a telescope, and blowing dust.)

The best forecast in the area was at our old favorite […]

Finally some observing weather

See Jane’s observing report from the same evening — some great binocular observing with Kemble’s Cascade.

The 20D mounted piggyback on the Traveler and Mach One GTO mount, hoping to catch comet PANSTARRS on its first opportunity.

Several months ago, David Green of the Santa Clarita Valley Photographers Association invited me to give a talk on astrophotography […]

Hot, dry astronomy

Observing report for June 16, 2012, Amboy, CA

The forecast for Amboy had a high temperature of 104°F and a low of 72°F. […]

Galaxy season

Observing report, April 21, 2012, Amboy, CA

We’ve had a string of bad luck with new moon weekends for the past six months, so when this new moon Saturday showed nearly perfect conditions, Jane and I were quick to pack the van and get out […]

Double your pleasure …

Chuckwalla Bench, Colorado Desert, California, 29 October 2011

As promised, last weekend was the first of two excellent dark sky weekends this month. The weather turned out to be perfect for this one as well.

Jane and I went to our old favorite spot off I-10, Chuckwalla Bench, on BLM land south of Joshua Tree in the Colorado […]

Observing at Amboy Crater

It's very easy to miss this sign from National Trails Highway, the delightful old U.S. Highway 66.

This month is blessed with two very good dark sky observing weekends, and we opted to take the first one at a spot we’ve been thinking about for a […]

The snow-capped peaks were beautiful from the Foothill Freeway

It had been several months since our schedule, the weather, and the moon phase all cooperated to give us a chance to get out to our favorite astronomy spot. Jane and I, joined by Dave Hasenauer, ventured […]
