Tell us your sky quality

Regardless of Bortle class, give me some clear skies.  I'd happily swap a drop in Bortle and have more clear skies.

I also vote for more clear (and moonless) skies, but not sure if I want to give up my bortle class.....?. Here's a series recent of readings off my iPhone using the DSM app, which average at the lower end of Bortle 3, but with several readings in the Bortle 2 range. I usually take 4 readings one after the other pointing towards the zenith, but facing roughly E,S,W,N in sequence. The actual phone camera angle (90 deg being vertical) is shown, so somewhat less than the zenith and generally tilted slightly in the direction I'm facing.

I wonder how receptive a phone app is in comparison to a Unihedron SQM-L device in accurately assessing in measuring sky brightness?

I use the Dark Sky Meter app for iPhone. It definitely is not as reliable as a dedicated SQM meter and is only capable of readings down to ~21.5 SQM, so I would take any readings better than that with a huge pinch of salt. When my sky is truly at its darkest, I sometimes get a warning ‘too dark for this device’. That said my readings broadly fit to on line estimates of sky quality where I have used it, so i think it’s a reasonable guide. I’ll accept Bortle 3 as likely correct, but as for Bortle 2, nah, that’s probably wishful thinking..... ? 

Cheers, Geof

But that doesn't match my experience, M31 is, at best, suspected on an excellent night.

It suddenly occurred to me that when the next Carrington Event happens (as it surely will one day, resulting in the end of all electrical power and the consequences that go with that), us astronomy nerds would finally all have Bortle 1 skies at last!!! 👍:)

I'm not entirely unconvinced that we might see a return to the 3-day week next winter :evil4:
