How do you rate someone on the classifieds?

Posted By dan hilts
When you respond to someone's ad, or they to your's, a rating ticket is issued that is good for 30 days. You can access the ticket by going to your account menu,(top right corner of the screen or left margin), and scrolling down to the ratings section. From there, click on unused ratings and follow the prompts.

Favorite Snack While Observing?

Posted By dan hilts
Key lime pie. It can vastly improve the observing if you buy it at the right place.

Saving Gas?

Posted By dan hilts
I've adjusted my commuting times. Under good travel conditions I can hold a steady 60mph without a lot of stop n' go and that yeilds a pretty good 40mpg. Under heavy commute on the same route there are stretches where I won't get 20mpg and I won't average 25. I has taken a bit of will power but I am also resisting the urge to pass everything in front of me. I'll get out from behind a stone thrower but I simply back off from the vehicles I used to pass.

I've gone from using a tank and a half to using just one full tank every week

Eyepiece-Nervosus

Posted By dan hilts
Accuracy varies. I know that there have been cases where different distributors of the same eyepiece sets from the same manufacturer have offered slightly different focal lengths. I suspect that sometimes manufacturers will round off the number (maybe because it fits nicer when etched on the eyepiece.) Other times, the focal length stated just seems wrong. I have a 17mm Plossl that seems to give more magnification than a 15mm Erfle that I have.

You can measure the focal length directly but it is difficult to do accurately. See this post.

book on double stars

Posted By dan hilts
Hi Tim

Have you seen the SAC double star data base? This isn't a book but it sure has a lot of info including a 39 page list of doubles sorted by constellation. It is available in several formats including Excel so you can sort and filter as you see fit. I printed a copy and stuck it in plastic liners for field use. With a decent star atlas, it's all I use

Star Explodes - I apologise

Posted By dan hilts
Even if it had been in my back yard I wouldn't have seen it through the clouds and haze during the last few months. (I know, wrong forum!)

Very funny

Posted By dan hilts
Can't say I agree with you. The Swastika was unnecessary and adds nothing but bad taste. Not worth the time to read, but then, I'm a Canuck.
