Marilyn needs help

Marilyn, from up north, emailed me, out of the blue. She had a few questions for me.

• wanted a summary of my astroimaging lecture
• had an 8 inch Dob, which needed columnation [sic]
• needed to know what items were required to take images through the eyepiece

Ah. OK...

I reminded her that I had provided a double-side handout with lots of good information on it, equipment recommendations, exposure times, f-stops, etc. If she couldn't find it, I told her I could send her another copy...

Sent her the web links I referred to.
