Reply To: Practice sights for a beginner.

[true]

For my beginner exercises I got a practice bubble that replaces the telescope on the sextant. I ordered a 5 year old almanac (pretty cheap). If i’m correct, I think I read that the sights come close to repeating every 5 years (?). My first noon sight try got me within 15 miles and I was sloppy with the timing. Any suggestions on timing? I tried to use my phone stopwatch. but cumbersome, so I’m thinking a regular old stopwatch.

Has anyone had a problem with sunlight leaking through the bubble horizon from celestaire? I got a pinpoint flash of bright light that was disturbing, even with the sun shades in place. Maybe reflecting from the glass level on top of the sight?

Thanks for any input and corrections.
