    Submitted by Roland Roberts on Wed 05 13 2009 09 08 The announcement should have been made earlier today and was if you were in class that we ll be meeting Saturday evening due to weather Tonight is supposed to be cloudy and hazy but tomorrow promises at least clear spots to do stargazing Or at least moongazing So same time and location just one day later We will be trying attempt number 6 to hold a stargazing session in Shore Road Park The moon will be in the first quarter phase and Saturn will be high in the south after sunset Because sunset comes so late this time of year we won t be able to start until about 8 45 although the moon will of course be visible pretty much all day Read more about Stargazing at Shore Road Park Log in to post comments TV Turnoff Week Stargazing Rain Date Submitted by Roland Roberts on Tue 04 21 2009 22 03 We will be trying once again to have a stargazing time in Shore Road Park see map below This is the rain date for yesterday s outing but the weather is not looking very good at this point Since the sun sets later now we can t start until 8 30 TV Turnoff week occurs this year duing the 3rd quarter phase so the moon will not be visible during our outing but Saturn should be visible and we can take a brief tour of the constellations and stars bright enough to be seen above the city lights Read more about TV Turnoff Week Stargazing Rain Date Log in to post comments NEAF and NEAIC Until Next Year Submitted by Roland Roberts on Mon 04 20 2009 11 32 We returned last night tired but happy from this year s NEAF conference The vendor turn out was good and overall attendance appeared good too although it was little hard to tell from our perspective We spent most of the two days in the children s area helping with the various activities including a comet demonstration followed by a craft activity making 3D constellation models Orion and the Big Dipper some informal demonstrations to understand the moon s phases constructing spacecraft models and more Alas I did not get to attend the showing of Mars 3D a new movie which made its debut at the show so I guess I will have to wait for it to be officially released Read more about NEAF and NEAIC Until Next Year Roland Roberts s blog Log in to post comments Pages first previous 4 5 6 7 8 9 10 11 12 next last Navigation Calendar Gallery Constellations Messier Objects M27 The Dumbell Nebula Resources Astronomy Books Buying A Star Buying A Telescope Clubs and Organizations General Interest Imaging and Astrophotography Magazines Mailing Lists and News Groups Science Toy Suppliers Software Weather Information Tips and Tricks Roland s Corner Recent content About Copyright Search form Search User login Username

  • Welcome to astrofoto.org!
    to get to any star parties or meet members from any clubs in the area for nearly a year Usenet news on sci astro amateur was a lifesaver Most of the time we were viewing from our 3rd story porch in Queens in the eastern part of New York City Views to the west were compromised by massive light pollution from Manhattan and during the coldest months the city generates significant heat that ruins the seeing even as high as 60 degrees above the horizon Still there are plenty of things which can be seen with the 8 inch scope or for that matter with our 10x50 binoculars In October of 2002 we moved to Bay Ridge Brooklyn We no longer have the 3rd floor porch but the skies actually seem to be darker Some of this is because we are near the water which means that in some directions there really is less light pollution We ve also acquired some camera equipment and a several telescopes as Roland has gone on a shopping spree not really it just kind of accumulates At this point we have a couple of smaller scopes includeing a 90mm f 5 refractor its bigger
