Naked Eye/Binocular Astronomy Events :

Feb 28 to Mar 7, 2018 Venus-Mercury “pass in the night”

The western sky after sunset will have two Evening Stars for a short while at the start of March. Venus and Mercury appear as double Evening Stars in early March with a nice close approach of about 1 degree on Mar 3. Venus at magnitude -3.9 far outshines Mercury at -1.2, but it is close to maximum brightness about this time. Venus has been climbing comparatively slowly into the western sky but Mercury is moving faster and catches up to and passes Venus March 3. Mercury reaches its farthest point east of the Sun on March 15 and then starts back sunwards again so its sojourn as second Evening Star is short-lived. Venus on the other hand will grace the western sky until the start of fall or so.

Mar 3 VenuMerc
Diagram from Starry Night/Simulation Curriculum

On Mar 3, the small separation of the two planets allows them to be seen in the FOV of a low power eyepiece and each will exhibit a phase if you can get past the glare. Both are waning gibbous, but Mercury’s phase is farther along and should be easier to see than that of Venus. This will be a very nice view even in binoculars!



March 3, 2018 Sat: Venus-Mercury Appulse
The western sky after sunset is where two Evening Stars meet in a close approach of just over 1 degree. Venus and Mercury are separated by 1° 4 min as they set around 7 pm that evening. Venus has been climbing into the western sky and Mercury moving faster catches up to Venus and passes it tonight. Mercury reaches its farthest point east of the Sun on March 15 and then starts back sunwards again. Venus on the other hand will grace the western sky until the start of fall or so.

From Our Astrophotographers:

ISS transited super Full Moon Dec 3 at 10:12 pm EST!
Four BAS observers get video and images from TWO Allenford locations.

BAS observers Lorraine Rodgers, Brett Tatton, Frank Williams and John Hlynialuk captured the transit from two locations along the track and got it crossing the centre of the Moon (left composite JH) and along the western edge (right composite FW). Lorraine captured the event on a cell phone held up to her telescope and Brett observed visually. John’s composite image consisted of 13 single frames (of the 27 in the video) composited with PhotoShop and the video was shot with a Canon 6D through a 5-inch Maksutov with focal length 1540 mm, at f/10. Composite by Frank, observing from his observatory north of Allenford, was taken in video mode on a Canon T2i mounted on an TEC 140mm (5.5-inch), f/7 refractor at 980 mm focal length (with Canon T2i, effective f.l. is 1568mm). Coincidentally, the two have the same focal lengths and thus image sizes. Both final images had some colour corrections applied along with sharpening and levels adjustments. Time of transit for left image was 0.91 seconds, right image was 0.71 s and in both composites only the second frame of the videos shot was used.

PS: This image and story has appeared in the March/April issue of SkyNews -see pg. 6.

Andromeda Galaxy!
Frank Williams does it again.

_90_min_m31_oct-20-crop_695K


Frank Williams took advantage of a few clear hours to capture our favourite external galaxy, M31. As he explains in more detail below, this was a relatively short exposure one a small refractor and an indication of what is possible with modern optics and tracking mounts. He writes:

It is a work in progress a mere 30 minutes 10 x 3 minute exposures in each of red blue and green filters for a total of 90 minutes Friday night. I used my Tec 140 mm apo (refractor) with SBIG 11000 mono ccd. (11 Megapixel) I cooled it flat out to get chip to -30C for minimum noise.  Losmandy Titan mount in my front yard guided with my Televue 85 and a Starlight Express guide camera. That Televue is a workhorse! M31 image you have from it with Canon T2i was not bad either but aperture and cooling help a lot.

I was disappointed Wednesday night by the sky conditions. M31 in Webster with good conditions is a marvel to behold.‎ I look forward to another Webster night this fall with better conditions. Before the winter clouds. -Frank

Frank Williams has submitted another stunning astro-image! The image below of globular cluster M5 in Serpens is a 3 hour exposure taken with his 5.5” (140 mm) refractor telescope.
He writes:
It was taken with an SBIG 11000 CCD mono camera with chip cooled to -25C. The exposure is 30 minutes luminosity (10 x 3 minute exposures) 1 hour each through red green and blue filters (2‎0 x 3 minutes each) 70 individual images altogether,  through a TEC 140 mm refractor from my front yard skypod  observatory in Allenford. Processed (stacking, etc.) using Pixinsight. Losmandy Titan mount and a KW kwikguider. Images taken over the few clear nights over last week. “

m5 3.5 hrs

The star to the left is double star 5-Serpentis, a 5th magnitude star with an 10th magnitude companion about 11 arc-sec away.

Info for M5 from Wikipedia:
M5 is, under extremely good conditions, just visible to the naked eye as a faint "star" near the star 5 Serpentis. Binoculars or small telescopes will identify the object as non-stellar while larger telescopes will show some individual stars, of which the brightest are of apparent magnitude 12.2.

M5 was discovered by the German astronomer Gottfried Kirch in 1702 when he was observing a comet. Charles Messier also noted it in 1764, but thought it a nebula without any stars associated with it. William Herschel was the first to resolve individual stars in the cluster in 1791, counting roughly 200.

Spanning 165 light-years in diameter, M5 is one of the largest known globular clusters. The
gravitational sphere of influence of M5, (i.e. the volume of space in which stars are gravitationally bound to it rather than being torn away by the Milky Way's gravitational pull) has a radius of some 200 light-years.

At 13 billion years old, M5 is also one of the eldest globular clusters in the
Milky Way Galaxy. Its distance is about 24,500 light-years from Earth, and it contains more than 100,000 stars, as many as 500,000 according to some estimates.

Auroral Displays

Auroral displays in our area are declining as we have passed solar maximum. There have been periods of "blank Sun" where sunspots have been totally absent for a time. However, at far northern and southern latitudes near the auroral ovals, sometimes magnetic disturbances from the sun produce auroras even without visible sunspots. So if the auroral oval in the graphic below is showing an intense RED, aurora borealis may be visible from your location. The graphic is updated regularly with time indicated at the top in UT so subtract 5 h to get local EST, or 4 h for DST. (Use the appropriate factor for other time zones). For more information click here: NOAA home website.

Current Auroral Oval not available right now
