Hey guys. For. A while now, i have been wondering, just how much difference does a dark sky make. I live in moderate light pollution, as i live in the city.The orion nebula is just a little fainter than most stars when viewed with the naked eye.
The limiting magnitude for my 8" dob so far(that i have tried) is 8.4. i could just make out the crab nebula at 37.5x . extremely faint and just visible with adverted vision.I can also see the blackeyed galaxy quite clearly.
I will be going on holiday in the summertime.I ll be visiting a place with clear dark skies.I will bring my 5" Skywatcher heritage with me. How many inches of aperature will the dark skies"add" to my scope compared to its original aperature at a light polluted location.Will it be able to rival my 8" dob?
Congratulations to Welsh photographer Alyn Wallace for getting National Geographic Photo Of The Day for these pictures of the Elan Valley night sky.
Hi there, our Astro group were booked into our normal dark skies venue for an observing weekend in February. Unfortunately, the accommodations are now going to be undergoing renovation and will be closed for the first 3 months of the year. We are looking at a couple of alternative venues. These are field study centres, one at Blancathra near Keswick and the other Malham Tarn in the Yorkshire Dales national park. Wondering if anybody has any observing experience of the skies in these areas.
