  1. Deep Sky This Month - April 2017 (Northern)

    by , 03-31-2017 at 06:21 PM
    Here we are in April now, and I am sure at least some of you are fighting with clouds and rain. But for those fortunate enough to have clear skies galaxies abound. This month for our northern targets we shall visit the front leg of the great bear for one of my favorite non-Messier galaxies. Then scratch the shoulders of our celestial lion for a galactic duo (or is that a trio?). Four our southern friends we will visit the profusely rich constellation of Centaurus for three bright galaxies that ...

  2. Deep Sky This Month - April 2017 (Southern)

    by , 03-31-2017 at 06:19 PM
    Southern Celestial Hemisphere:


    NGC 5128 (Centaurus):

    Lenticular/peculiar Galaxy, mag=6.8, size=25.7’x20.0’, SBr=13.3 mag/arcmin2

    The celestial centaur is a large and bright constellation that is rich in a variety of DSOs. One of its more famous possessions is the radio galaxy Centaurus-A. It is also known variously as Arp 153, the Hamburger Galaxy, Caldwell 77 and even Dunlop 482 (James Dunlop discovered this galaxy in 1826). I have had the ...

  3. Celestron SLT 130 - Alignment and first equipment purchases.

    by , 03-21-2017 at 08:53 AM
    Here’s a reply to a question in the forums, which I thought handy to anyone starting out with the Celestron Nexstar SLT 130.
    The following all assumes you've loaded a bunch of batteries in - we'll get to power options in a sec.

    Align your finder first
    Do this in daylight and make sure you do this first as it helps a lot centering and aligning when doing the typical 3 star alignment. I used a street light at the end of my street.

    There are three dials ...

  4. Deep Sky This Month – March 2017 (Northern)

    by , 03-04-2017 at 01:02 PM
    As we head into March the minds of more than a few observers tend to drift to thoughts of galaxies. With winter turning into spring in the north and summer into autumn in the south, a large and rich swath of prime galaxy real estate is readying to take center stage.

    Cutting a wide path from Centaurus through Hydra, Corvus, Crater and Sextans, it stretches into Leo with a significant concentration in Virgo that flows into Coma Berenices. On northward it enriches the fields of ...
  5. Deep Sky This Month – March 2017 (Southern)

    Southern Celestial Hemisphere:


    NGC 3115 (Sextans):

    Lenticular Galaxy, mag=8.6, size=7.2’x2.5’, SBr=11.5 mag/arcmin2

    Now let’s swing south of the celestial equator for a couple of fine objects. Our fist one is an amazingly bright sliver of light that I think surprises many when they happen upon it. Located in the southern part of this dimmer constellation, it lies almost exactly halfway between and slightly north of a line between mag 5.1 Gamma and ...
