    Default Is winter truly better for imaging compared to summer?



    Hi guys, need to pick your brains a bit.

    I'll most likely be heading to Ayers Rock or Alice Springs sometime this year. My sis just came back from there on a round-Aust trip and she actually joined a casual astro tour. The tour guide that said that astronomy (I doubt they did any imaging) was best during Winter and I just wanted to confirm if this was truly the case. Would it be a case of lower humidity, better seeing, or something else?

    Thanks

    Yes. The sky is crisp and steady and the colder my camera and optics are the better they work. (to a point). around 35-40 degrees is great for me as opposed to 70-80 in the summer months..

    Lower humidity, lots of 'easy' targets (M42 ) and the hours are better with longer nights too

    If it's clear, then yes. But around here we have way more cloudy days/nights during the winter than the summer.

    I agree that the usual reduced humidity would put a check in Winter's score sheet.

    However, the last person I'd listen to is a tour-guide on such matters. Now, bears might be a different story.

    I think Roger was asking about winter in Australia....
    I'm no expert on central Australia but I would think winter would be considerably better. For starters you have the longer nights. And in summer, the centre does get the peripheral effects from the wet season of the tropical north and you've got high temperatures in daytime and warm at night.
    Overall though the humidity is quite low as its as far from the coast as you can get.
    The main thing is that the skies are dark - although some hare-brained schemes around seem to want to destroy that with dazzling lit up displays

    Heres the climate data for Alice Springs: Climate statistics for Australian locations

    ETA: Drop bears are a problem in area with more trees but not so much in the Centre which has few trees

    Yes winter does give you the best views and pictures, but as far as I'm concerned winter is for ducks and penguins. Come on Spring.

    Looks like everyone is talking about weather. Yes winter has better atmospheric conditions than summer, but the DSOs are much more numerous during the summer. In Winter your looking out from the center of our galaxy, in summer your looking toward the center. Most of what you see is in our galaxy except for other galaxies.

    I just took a peek at Stellarium for Oz, at 25°S, and winter there actually coincides with the so-called Summer MW and is visible in the early evening after sunset. But coming from the tropics all my life, I'll probably freeze my nuts off in the process . Perhaps spring would be a better compromise. M42 at that time would be gone however, sadly.
