The BOEC was declared Canada's 15th Dark Sky Preserve in Nov, 2012. At the ES Fox Observatory, we have a large reflecting telescope (a 28-inch Webster, recently re-aluminized and working great!) and a 10-inch SCT on a GOTO mount that we use regularly in our public viewing sessions.


Click for maps to: ES Fox Observatory or Tom Thomson Art Gallery meeting locations.




Next public VIEWING EVENT (members and public welcome) is Oct 21 (8 pm) at Fox Observatory (Orionid meteor watch). Come dressed for a cool night.



Next BAS club meeting is Nov 1, 2017 (7 pm) at Tom Thomson Art Gallery.
(Members’ night)

Naked Eye/Binocular Astronomy Events :
Saturn still hanging in above western horizon but not for long.

IMG_156750_486KB

Image above is a shot of the western horizon on Oct 11 at 9 pm EDT. Saturn is the brightest light just at the tree line and the Sagittarius Teapot is partly visible to the left of the Milky Way. The Lagoon Nebula is still visible (between the two) but in the murk at the horizon. The star clouds above Sagittarius are prominent and so is the Great Rift leading up to the top of the image where you find the star Deneb. Look down and rightwards from Deneb to find the very bright Vega in Lyra and Altair is lower and to the left of the MW. The Summer Triangle stands high this time of year. If you look straight down from Vega about halfway to the horizon is a brightish star in Ophiuchus, Rasalhague, and we have an admittedly crude Summer Rhombus! Image by John H. taken looking south from my backyard in Owen Sound with Canon 6D and Samyang 12 mm lens at f/2.8, 20 seconds ISO 4000. This is a crop of about 50% of that lens field of view which in the original extended almost to Cassiopeia overhead.

Jupiter Viewing is Done, Check out Saturn (before it too sets in West)

Saturn is still visible for a few hours in the SW sky at sunset. Look to the right of the Milky Way as in the image above. The planet’s rings still stand out because they are at a maximum tilt our way. There are not many weeks of viewing left as it drops into the haze above the sunset horizon. Brian Ventrudo has created an excellent document with more information describing all the ins and outs of observing Saturn this season and has made it available at his Cosmic Pursuits website here:

From Our Astrophotographers:

ISS Transit successes!
BAS members get images!

20170927-DSC02534-Edit-2


Former BAS member Troy Johnstone caught this Sep 27 pass of the ISS over the Moon from near his hime in Alberta. He sent this email to accompany the image above: On a lark last week I looked up if the ISS would transit the Sun or Moon, and sure enough one week later it was predicting a transit. So earlier tonight I took my 120mm SkyWatcher, a Nikon 1.7x teleconverter, and a Sony A7Sii out to photograph it.


ISO 2500
1/1500 sec
600mm x 1.7 = 1020 mm
f/5ish (can’t remember what the teleconverter would make an f/5 telescope)

I used Lynkeos on Mac to stack images of the sequence to sharpen the Moon, but the ISS images are as is.
Troy

Image below is by John H. showing the ISS against the nearly full Moon on Oct 4. This is a composite of 8 frames out of 30 showing the silhouette passing over the Moon at 11:24 pm EST as seen in Collingwood, ON. The original was a 6D movie taken at 30 frames a second and produced exactly 30 frames of the ISS in the 1.0 second pass over the Moon. The camera was connected at prime focus to a 5-inch Maksutov telescope that gave a Moon that filled the whole frame. The path of the ISS was determined using www.transit-finder.com which allows you to input your latitude and longitude and then select a distance you are willing to travel. Usually in a month-long interval there are 6 to 8 possibilities to view lunar or solar transit (or both). Have a try, it is very neat to see the dark outline sweep across the Sun or Moon. Note that in Troy’s image, the ISS is illuminated by Sun since this was a visible pass. In the image below, the ISS was in the Earth’s shadow and not visible before the pass. An accurate time from a cell phone is required or you can connect to www.time.gov to get a display of the atomic clock time from the US National Institute of Standards and Time. There are also apps for your smart phone like SkyTime which do the same thing.

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
