Observing Intents / Observing This Week and Weekend?
« Last post by pnatscher on May 17, 2017, 11:16:16 AM »
The skies have cleared and I'm planing to observe at a local dark site the next few days.  Initially I would like to get out Thursday and Saturday nights.  Anyone game for one of our choice locations?

Venus at mag -4.29 0.7 AU away, and Uranus at mag 5.88 20.6 AU away, in one wide field of view.  10 magnitude difference!  Interesting, Starry Night Pro shows Venus maximum magnitude from Earth as -7.08.  Really?  Maybe it means something else.

Venus will have 50% illumination, 24 arc-second size.  Uranus will be 3.4 arc-seconds.

Sounds good, I think I'll be there.  ;-)

We have the pleasure having Steve Gottlieb give a talk focused on observing deep sky objects: Off the Deep End -- Challenging Observing Projects for the Intrepid Amateur. Steve will be giving a version of this talk in Cambridge, UK, to the Webb Deep Sky Society in June. You do not want to miss this presentation!!

 Is your observing experience getting stale? Do you find yourself either looking at the same objects each year and don't know additional interesting deep sky objects to view beyond the Messiers and the brighter well-known object

 Refocus by working on observing projects. For near 40 years Steve has worked on numerous fascinating lists of oddball galaxies, groups and clusters of galaxies, stellar and giant planetary nebulae, ancient open clusters and more. He’ll discuss how to jump-start your observing by delving into Hickson Compact Groups, Local Group Dwarf Galaxies, Palomar Globulars, Abell Planetaries, Vorontsov-Velyaminov Interacting Galaxies, Extragalactic Globulars, Karachentsev Galaxy Triplets and more. He’ll discuss his results using several telescopes up to 48-inch aperture.

 Steve Gottlieb has been an active visual observer since 1978 and currently uses a 24-inch f/3.7. He has observed the entire NGC catalogue (over 7500 entries) and a total of nearly 15,000 objects. Steve is a contributing editor to Sky & Telescope magazine and has written numerous deep sky articles detailing his various observing projects.

TAC Visual / Re: Action on Jupiter
« Last post by sgottlieb on May 03, 2017, 08:33:19 PM »
I missed the reappearance of Europa as I started viewing after the beginning of Io's transit.  I've just kept my 24-inch set up in the driveway and mostly using an 8-inch off-axis mask for an unobstructed view.

On other recents nights (after returning home from 4 nights on the 48-inch), I've been tracking down doubles in Coma Berenices and Canes Venatici, and on Monday night helped put on a public star party for the physics students at Albany High

Steve I saw last night's action too. At the same moment Io started its transit you should have also seen Europa reappear from behind the planet's shadow. It flared as a tiny point then grew to a full disk in about a minute. Way cool. I was able to watch  Io transit along the belt as a bright disk until a few minutes before its shadow looked like a nibble was taken out of Jupiter 's limb.

I've also been enjoying some high power 553 - 850x views of the moon's terminator. Getting ready for close doubles in Cancer tonight

With the moon now dominating the early evening skies, I've been doing a little Jupiter gazing in my driveway.  On Sunday night, Europa starting transiting the disk of Jupiter around 11:30 and last night (Tuesday) it was Io's turn.  It reached the limb around 10:00 PM and after 10:30, its shadow started marching across the face of Jupiter along the north equatorial belt.  This last sequence of events repeats next Tuesday, though a bit later.

NGC/IC Project / Re: Corrected NGC v0 online

Steve is right.  Bob only built images for the first 99 IC objects, though we do have good identifications, notes, and preliminary data for all 5386.  I hope we can get this back on line soon.

I've observed with a 'biggish' 4 day old Moon before.  Luna will be only 24 degrees up in the west.  Transparency will be very good.  Just look at objects overhead and to the east.  Wagner and I did just that from Coulter Row one night a 'few' years ago.  Was a good night spotting mag 14 galaxies.

Crilly! As you will have seen, I was at the Pinnacles Wednesday. I dunno what our buddy Peter is up to, figuring on waiting till midnight for a biggish Moon to set. But that's just me.
