RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

Comet Lulin - Barely There - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam. Note: The RF Cafe Forums were reconstituted in April 2021!

Below are the old forum threads, including responses to the original posts.

Greetings:

For reasons only an astronomer (professional or amateur) would understand, I got in the car at around 9:00 pm and drove to an open field around 25 miles south of Erie, PA. The glow of the Erie city was north of the ridge that runs along I90 as I chose an ice-covered hilltop from which to hunt for and hopefully photograph comet Lulin.

Clear skies in Erie are rare enough that the trip was worth the effort. Melanie braved the 13 degree air to ride along with me, although she wisely remained in the car with the heater running whilst I got out to do my comet viewing. 
 
Astronomy websites advised that Lulin should be visible with the naked eye. Maybe someone with better eyesight than me could see it, but it required the assistance of my 7x35mm binoculars to find it. Fortunately, Lulin's position near a readily identifiable group of stars at the rear of Leo, and especially with Saturn's presence, made finding the fuzzy blob easy enough.
 
The Minolta and tripod were nearby for an attempt to photograph Lulin, but since its timer will only keep the "shutter" open for 60 seconds, and because the comet was so faint, I figured it would not be worth the trouble. I'll have to leave the breathtaking images to the people with real motorized telescopes and cameras built for the job.
