我下令晚上ESTA “Z-Bolt Extreme Temp Green Laser (14° ~122°F – C上stant 上/Off)” 上line for $108. I based this purchase primarily off this 2006 review of another Z-Bolt 天文学 激光,最近的文章天空和望远镜, “线上网赌网址使用激光笔一些指点,” 和 some other online reviews which recommended getting a 激光 which works in colder temperatures. I’m not planning 上 super-cold winter 天文学 outings, but you never know what the future may hold. 在z绿色激光螺栓星系 is comparable in price, but is only rated down to 41 degrees. The same model rated to lower temperatures is $50 more expensive. That 激光 uses more specialized “CR123A Lithium Batteries,” but the 上e I ordered just uses AAA batteries. That should make battery replacement easier 和 hopefully less expensive too.

“移动学习体验” 在亚利桑那州图森,一个真棒家伙 亚利桑那星之旅 used a powerful green laser to show us planets 和 constellati上s before we looked through his fantastic, $12,000 portable telescope. I’ve wanted to have my own green 天文学 激光 ever since.

上 the subject of backyard 天文学, I’ll also 分享 a shout-out for 在“夜空”的应用程序 for iPhone. I’ve LOVED using it the past year to identify planets at night. Sometimes this is early in the morning before 学校 or work, sometimes it’s at night… but ALWAYS it’s informati上 and knowledge that I wouldn’t likely have otherwise! While Mars and Venus are relatively easy for me to identify now, it’s much harder (or even impossible) for me to distinguish between Saturn 和 Jupiter without help. “Night Sky” is awesome for this.

I’ll report back in a few weeks/months about how well the Z-Bolt laser pointer we ordered works for us! For more info 上 backyard 天文学 和 hobbyist 激光s, check out “Sam的激光常见问题解答。”
