Hi John thanks for information. Much appreciated. I have recently returned from Astro La Palma for a night photography workshop so the chance of some night photography would be fantastic. I have a pano head for stitched panos so I will bring that along with me. If you are interested (and have time ;o)), there are some photos from the workshop on my website: www.mjmayphotography.co.uk. I also took my first time-lapse which was interesting.
I will be arriving in Denver on the 23 June at 2:15pm on the UA26 flight.
I'm looking forward to the trip as storm photography is something I've yet to experience.
With regards to forecasts, which site would you recommend?
All the best.
