significant overlap between the two."
We are delighted to welcome back David as a speaker; he also has given us some fascinating lectures over the years, with intriguing titles, and this one is no exception!
2: Venus very close to Saturn, Jan 8-9
On the morning of Jan 8, Venus will lie just 1 degree above left of Saturn.
Next morning (Jan 9), as they rise at about 06.00, Venus will be only about 7' (less than a quarter of a Moon diameter) left of Saturn. As they rise higher the separation will gradually increase, to over 10' at 07.30. Try to spot Titan, mag 8.8, on the opposite side of Saturn, as they rise a bit higher (if Venus is at 9 o'clock from Saturn, Titan will be at about 2 o'clock). Venus will be 63 times (4.5 magnitudes) brighter than Saturn, and 100,000 times (12.5 magnitudes) brighter than Titan!
3. Comet is visible in binoculars Comet Catalina is now higher up in the morning skies, and will soon be circumpolar. Andy McCrea in particular has been getting some nice images - see the IAA website. As it gets higher, now in Bootes, it's in a darker sky, though it is gradually fading. It had amazing double tail structure, see this fabulous photo:
Visitors will be fascinated by the views of the spectacular winter constellations, Taurus and Orion and deep sky objects through our 12 inch telescopes.
The observing session will be held at the Planetarium and there will also be a free presentation of a spectacular Digital Theatre show at 7.30pm.
We hope to observe from 7.00pm to 9.00pm. If you would like to join in please be aware that observing can be done only if the sky is clear, the telescope cannot see through cloud and rain! The Digital Theatre show will go ahead regardless of the weather. Also dressing warmly is essential! If you already have a telescope or binoculars you are welcome to bring them with you for your own use.
If you are interested in participating please phone to book your place on 028 37 523689.
Here is an opportunity for astrophotographers in Ireland to showcase their work, presenting the wonders of the Cosmos at the Botanical Gardens in an exclusive exhibit in a collaboration between the Irish Astronomical Society (www.irishastrosoc.org) and the Irish Federation of Astronomical Societies (www.irishastronomy.org), which includes members of its member clubs.
The Details: Irish astrophotographers are invited to submit an image to be showcased to the public as part of a display highlighting the wonders of the Universe for a limited time from February 2nd to 21st 2016. The Botanical Gardens in Dublin has freely allowed the use of their lobby to display 100 images mounted for display, and incorporate additional items like (a limited number of) telescopes, large format poster displays and more.
The Criteria: Your photo can be submitted in digital or printed format. The following are guidelines:
1. Digital prints must be at 300dpi and in its largest format aspect ratio.
2. TIFF format is preferred, or high resolution (300dpi) JPEG is also allowed (RGB or CMYK is allowed).
3. Physical prints must be of a high quality (uncurled or folded) and can have a gloss or matte finish. Do not send mounted prints.
4. All photos will be fitted in an A3 mount and frame, and therefore may be subjected to cropping, if necessary.
5. All images submitted MUST have information about how the image was taken (equipment, location, software and techniques used, etc.), information about the object(s) shown, and the photographer's information.
Interested? Digital images can be sent via email to email@example.com as an attachment (do not include off-site links to images), while postal images are to be sent to Botanical Exhibition ℅ Seanie Morris, Anstee, Daingean Road, Tullamore, Co. Offaly.
