Online Observing

Posted on by July 20, 2021

Winter in the Western Cape, South Africa, leaves less opportunity for me to do deep-sky observing. It’s supposed to be our rainy season and I am accustomed to my telescope going into semi hibernation. I love the rain and we need the rain but when clouds gather just to show they have enough muscle to cover the entire heaven and I feel no raindrops falling on my head, I get really depressed.

There is some consolation in the fact that these days one can observe online as well. I have become a member of Slooh which feels like the most straight forward online telescope system for an enthusiastic amateur like me. I took baby steps at first and signed up as a crew member, which means I did not get to control the robotic telescopes but could observe the objects reserved by Slooh apprentices and astronomers in real time. Apprentice  and Astronomer members pay a subscription and crew members go along for the ride. Now a month later I’ve decided to take my second step and updated my account to an Apprentice. I will now get to reserve time on the telescopes and do settings and very cool stuff. Mostly I’ll still  go along for the ride. Honestly the less I have to fiddle with alignments and settings when observing, the better.

Usually when I go online I have access to content instantly but reality soon dawned when I realized that Slooh telescopes are live and have weather issues just like anywhere else. At least Slooh’s website has so much interesting stuff to explore while waiting for the dots on the telescope page to turn green for go.

Instead of doing astrophotography I sketch. Doing sketches while observing through a remote robotic telescope seems like crooking big time. Most of the rules that apply when I’m observing through my telescope fall by the wayside. How can I determine co-ordinates when the stars do not drift across to the west in the eyepiece like they do in my uncomputerised telescope  Trying to determine star colours seem to be less obvious through the Canary Island telescopes but nebulae are so much easier to sketch when not having to nudge the telescope at the same time.

I always keep a log of every observation – even when online. I know I will not be able to submit my online observations to the Astronomical Society of Southern Africa for I am such a goody two shoes and that would be like lip syncing. On the other hand, I am observing in real time but just without bug spray and I will be taking my online adventures into account when I tally the grand total of my deep sky observations.

Bingo – To be able to complete my notes I scoured the internet for hours to find specs on Slooh’s telescopes. I almost joined a forum of disgruntled people who could not find any specs and were accusing Slooh of being a scam. Luckily I went onto the website again to see whether Canary Two had come online and this time I noticed a cheeky arrow over a pink button on the telescope page. It’s amazing how much more info one can find if you know where to look. Each location also has a webcam and from that footage I can sort of guess atmospheric conditions. Apparently if the stars seem elongated, the wind is blowing a gust!

To get the most from of an online session I try to get as close to the real thing as possible: lights off when I’m visiting Canary Island, curtains drawn for Chile. I use my regular sketch pad with red light and have coffee from a flask. By adjusting my computer’s display I can become relatively dark adapted.

Doing Astronomy online is a far cry from looking directly through my own telescope. I thought there would be no accelerated heartbeat, no oohs or wows until my first observation of a red dwarf thanks to Slooh’s Chile One. “Kapteyn’s Star” was absolutely breathtaking through the 14” Smidt Cassegrain. Mostly when I observe galaxies I see small smudges but one Slooh astronomer member opened up a new universe for me when he reserved time to observe NGC 1433 on Chile One. WOW!

Thanks to Slooh, apprentices and astronomers for giving us this wonderful opportunity and for sharing their observing time.

 

Journey of Self Discovery

 Aug 2010

What’s it all about, Alfie?  Where are you going, Billie?
I am at the age where most people start paying more attention to life’s more serious issues. Those with faith issues revert to “Never on a Sunday”, pursue all kinds of weird religions or join a church choir if the issue is not that great. Those with health issues join gyms, Arthur Murray, do the Camino de Santiago and then need knee replacements afterwards or buy exercise bikes to use in the comfort of their own homes.Many who ask the really big questions try to find the answer in all the above mentioned plus try tricky love affairs, get divorced or remarry but all to no avail and become depressed.
Will we ever know where we have come from and where we are going?
By doing Astronomy , I have embarked on an amazing journey of self discovery. I often dreamed of far away places and suffered jet lag to fulfill some of those dreams.
A few years ago I started dreaming of seriously far away places – places even further than the Moon. One evening I took my binoculars, which I had always only used during the day, and looked up at the Milky Way. I should have found a more practical way to observe the magnificent sight. Lying back on a recliner or folded blanket instead of arching my neck all night would have prevented a seriously stiff neck the following morning but all was worthwhile.
I was hooked  and got my first 4 inch Newtonian telescope. I sought out the brightest stars and hey! I found a really big one with  two little stars on either side of it – all lined up in  neat row.  I was looking at Jupiter and could actually see horizontal bands across the planet.The little stars on either side were four of Jupiter’s moons. I was looking at a place about 778,570,000km away, experiencing heart palpitations but no jet lag!
Soon I realized that I would need a more sophisticated vehicle. I desperately needed to travel even further. I needed to reach the Hollywood of the Universe 1500 light years away called M42, a birthplace of stars in a very huge cloud of extremely hot gas and dust particles.My Bushnell 8 inch Dobsonian took me there on 16 March 2007 and ever since the two of us have been exploring the night skies. To really appreciate what I was witnessing, I took to sketching the objects which I feel deserve this extra effort instead of just jotting down a bunch of facts or clicking a camera shutter. Nellie has a big sister now, a 12 inch Dobsonian named Stella.
Sometimes I feel the necessity to put my Astronomy observations and sketches to the test and submit my work for scrutiny by experts. Receiving my first merit certificate was fantastic and cause for excited celebration.
Being part of an Astronomy group provides a lot of fun. The camaraderie is great and the friendships are precious. Introducing people to the night sky and sharing my enthusiasm also gives me great satisfaction but most of all I cherish the hours I spend alone with my telescope under a star filled sky, far away from city lights.This is when I get to know myself best, where I come from and where I am going.
