helped Sharmin align

Sharmin has one of the RASC Toronto Centre's 8" Dobsonians. In fact, I delivered it to her and gave her a quick tutorial on the balcony.

But when she relayed that she wasn't seeing or finding things, and then gave up, I started to wonder if the finder scope had been bonked. I thought we had checked it...

I walked her through some checks. Suggested she start in daylight, targetting a distant stationary object. Pointed out the two screws on surrounding the finder scope. Reminded her that precision is required. Then urged her to repeat the steps but with a higher power eyepiece. And then encouraged her to repeat this process once again in the evening with a bright celestial object like Vega.
