Balcony Astronomy from Edmonton – Abdur Anwar

Edmonton RASCal Abdur Anwar writes: I was able to see Jupiter, Saturn and Mars from the balcony on Wednesday and got some test images in preparation for summer. Mars is supposed to get pretty high up this year by October. Now is a good time to practise. Also got the blue snowball nebula.
I used a grey tube C8 at f10, ASI1600MM camera and an EQ6R mount.

June 21st Annular Eclipse of the Sun from India

Time lapses by Neelam and Ajay Talwar and family in an amazingly complicated setup in the midday heat – note the giant fans! They did a wonderful job of capturing Bailey’s Beads peeking through the lunar craters and mountains along the thin rim of sunlight at the edge of the Moon at mid-eclipse.

Noctilucent clouds from Osoyoos – Debra Ceravolo

Debra’s comments on her Facebook page: “Many people like me have never seen noctilucent clouds and here I have seen and photographed four different events this month. The frequency of these special iridescent clouds is increasing due to climate change. Noctilucent clouds or NLCs form way out in the mesosphere at the edge of cold space. Meteor ‘smoke’ lingers there and ice crystals form around that. The solar minimum causes the thermosphere/mesosphere to be even colder and terrestrial activity affects how water vapour gets up there. So it’s water vapours and extreme cold that form NLCs. This photo was taken the evening of June 27th from my home in southern BC.”

Recording Astronomical Observations – Joe Carr

Joe reviews how he records his observations by using a combination of an observing log, photos, diagrams, and he also shares how he stays motivated and shares his observations online.

Planet Nine or Planet Nein? – Reg Dunkley

On 23 June former NRC/DAO Plaskett Fellow Samantha Lawler gave a public outreach lecture from her new Regina home entitled, “Planet Nine or Planet Nein?” She radiates enthusiasm for studying the outer solar system and includes some excellent graphics to help her audience gain new understanding in an enjoyable fashion. Here is UR’s message with links; if you watch the video I’m sure Samantha and UR would be grateful to receive your feedback via the form they provide:

“We hope you enjoyed “Planet Nine or Planet Nein?” with Dr. Samantha Lawler. A few links and attachments follow:
1) Please complete this survey – we would like to hear your feedback.
2) Please click on this link to view the recording of the presentation.
3) Attached are Part 1, Part 2, and Part 3 of the slide deck of Dr. Lawler’s presentation
Again, thank you for your interest in the University of Regina’s Research with Impact!”

UVic Open House Presentation: Using Telescopes as Time Machines

Be sure to catch the following UVic Webinar that begins at 7:30PM on Wednesday June 24th: Using Telescopes as Time Machines by Nishith Eluri and Jonathan Ranallo

“The telescope is perhaps an astronomer’s most useful tool, allowing them to study and understand things billions of lightyears away, in places we could never dream of visiting in person. With only a small telescope and a dark view of the heavens, anyone can see with their own eyes the beautiful planets and moons of our Solar System, faraway spiral galaxies dancing and interacting with each other, the nebulous death throes of ancient stars, clusters of young stars just leaving their nurseries, and a myriad of other celestial wonders. This week, our volunteers Nishith and Jonathan will delve into the history and inner workings of telescopes of all types, from Galileo’s first hand-made refractor to the Earth-sized telescope used to image a black hole, and everything in between.”

Christopher Go Planetary Imaging Tutorials

Zoom has allowed accomplished members of the astronomical community to share their expertise in a Webinar environment. These sessions are often posted on YouTube to replay at your leisure. There are so many postings, however it is easy to miss some valuable talks. In the following three links acclaimed planetary imager Christopher Go shares his expertise. These sessions may help some local planetary and lunar imagers to further hone their skills. These sessions were hosted by Woodland Hills Camera and Telescopes in April 2020.

Using New Horizons Probe for Parallax

The distance between the Earth and New Horizons offers a very long baseline that facilitates parallax measurements. Check out the interesting article here.

CANadian Virtual Astronomy Seminar Series (CANVAS)

The next talk in the CANVAS series will be given Paul Weigert of Western on Monday June 22 at 11:00 PDT. Dr. Weigert’s talk is titled ‘ Interstellar asteroids and comets: what are they and where do they come from?’

Visit the CANVAS webpagehttp://astroherzberg.org/canvas/ – for the schedule of talks, a link to the YouTube channel, and links to the recorded talks and upcoming talks.

Noctilucent clouds from Edmonton – Alistair Ling

Daytime Lunar Photo from Mike Nash

During this cloudy interlude RASCals have had to resort to desperate measures to capture Astro objects. Despite multiple layers of cloud and a rising Sun, Mike managed to get a remarkable amount of detail in this image taken at 9AM on Sunday June 14th. He writes: “The filter works well enough, but not perfect – on screen the sky is grey rather than a completely visible light-blocking black. Alignment points (for stacking software) needed to be set at a much higher brightness than I would normally do.” Check it out

Alister with one of his patented moonset shots from Friday – “The view from Kinnaird Park, birds chirping, geese honking, lilac bushes perfuming the damp coolness. So much to image lately! It will take a while to process the time slice, time-lapse, valley fog time-lapse. How do you like your Mead/Honey Moon? Pale, yellow, peach, amber?”

Undulating fog in the river valley – a time-lapse captured by Alister. The movie really shows the bulk motions that are not visible to the eye. Sped up 100X. Definitely on the meteorology side of things, but the Moon is in the movie at the start!

Masked Men Make Off with VCO Telescope

On June 4th, vigilant lunar astrophotographer Mike Nash captures RASCals in the act as they conduct top secret mission to ship Victoria Centre Observatory scope to a telescope spa in the Los Angeles area.
