- Astrophotography sessions

- bortle reading
Picked this up as the developer of the iPhone app has quit development and I wanted accurate readings to help plan my Astrophotography sessions. Works well and is easy to use.
Very nice light instrument that is easy to use and accurate. Also light and small.
I always wondered how dark the sky was where I live. The maps always said that I was living in a rural sky but now with this device, I was able to get a true reading on the Bortle scale of usually over 21.60...much darker than I realized. By measuring the sky before I pull out my telescope, I can get a very good preview of the night viewing. The sky quality meter has proven to be worth ever penny.
easy to use, values fairly consistent.
Excellent: I would definitely buy from you again.
