Are You a Serious Observer?

By Bill Pellerin

Houston Astronomical Society

There is a lot written and said about amateur astronomy, but one thing I hear often is that someone is a 'serious observer' (not to be confused with a Sirius observer, which would be easy). Are you a serious observer? Am I?

 

I've heard it said that it's a requirement to be called a 'serious observer' that you own a large telescope.

Astronomy magazine's podcast (by Michael Bakich) offers observing objects for various sized telescopes. Early on, Michael referred to large telescope owners as serious observers. After receiving feedback from listeners with smaller telescopes, he doesn't make this association any more.

 

Phil Harrington, whose latest book is Cosmic Challenge said in an interview in our Houston Astronomical Society's GuideStar newsletter (in an interview written by Reflector contributor Clayton Jeter)  "I believe in 'go big or go home'".  By this, Phil means that you should have big goals, and you should try big things, but doing so doesn't necessarily require big telescopes. In fact, you can take a deep a dive into many observing programs with a good pair of binoculars. Phil responded to an email with, "In my mind, veteran observers should put themselves and their equipment to the test by trying to see targets that are at the edge of visibility for their instrumentation." Objects may be on the edge of visibility because they are dim, because they are small, because they are close to bright objects, or because they are difficult to identify in a crowded star field.

 

Barnard's Star is an example. It's a magnitude 9.5 star in Ophiuchus, but it is a bit of a challenge to find in a crowded star field. The star moves over 10 arc-seconds per year, so you have to know exactly where to look for it.

 

So, what are the characteristics of a serious observer? I exclude the requirement that a 'serious observer' only observes very dim objects with very large telescopes. So, if the quality of seriousness is not associated with equipment inventory, what is it?

 

Someone who is a solar observer and regularly (every clear day, for example) observes the Sun and records those observations with the intention of developing an in-depth understanding of solar phenomena is a serious observer. The Sun is the brightest object in the sky, so if someone can be a serious solar observer, then clearly any object, or set of objects observed in a serious manner can make an amateur astronomer serious.

 

There are plenty of observers of the Moon. While the moon has been observed, mapped by satellites, and visited by humans, not everything there is to know is now known. The work on lunar observing is not complete. My fellow Houstonian, Brian Cudnik has written a book, Lunar Meteoroid Impacts and How to Observe Them. Brian observed a meteor impact on the Moon visually in 1999 and discusses in his book opportunities for amateurs to participate in serious lunar observation.

 

Various observing organizations such as ALPO (Association of Lunar & Planetary Observers) coordinate efforts of observers of solar system objects, IOTA (International Occultation and Timing Association) works on lunar and other occultations, the AAVSO (American Association of Variable Star Observers) collects data from amateurs on variable star brightness over time to provide data to professional astronomers who are trying to understand stellar evolution.

 

Another friend of mine concentrated on seeing the earliest possible new moons (and latest possible old moons). He'd travel hundreds of miles to be in the best place to make the observations. Sounds serious to me.

 

The common characteristic of these organizations, and these observers, is the depth of effort and the depth of knowledge required to make the observation. These observers are not content to casually observe objects in the sky, they want to study the objects, they want to understand what they are observing and how the object fits into the universe.

 

How do you get to be a serious observer? You get there the same way you get to Carnegie Hall… practice, practice, practice (and effort). I read an article in the Scientific American ("The Expert Mind" July, 2006), and it said that the way you become proficient at something is by purposeful effort. Half-hearted effort won't get you there; your observing program must have a goal and a purpose and effort in the pursuit of that goal is required.

 

My observing purpose is to provide data on a regular basis to the AAVSO on variable stars with a goal of providing information that advances the understanding stellar evolution. I'm working on improving my data gathering and analysis processes and being able to provide more and better results.

 

The Astronomical League observing programs have introduced many an observer to object categories he or she would not have otherwise observed. These programs can lead to a passion for any of these objects and represent a valuable service to the astronomical community. Check out the observing clubs on this web site and see if any look interesting to you. Years ago, I completed the double-star club, and I've been a double star observer ever since.

 

If you can't decide on one, do the Universe Sampler club by Amelia Goldberg. You'll get introduced to many objects in the sky in the process of completing this one program.

 

You will be able to tell when you have become a serious observer; you'll be observing with a purpose and having more fun, too.

Amateur Astronomy – a solitary activity… best done with friends

by Bill Pellerin

An amateur astronomer is one person, with one telescope, observing under clear, dark skies, right? It's you, your telescope, and the sky. Much of my observing is like that, but not all. You can (and you should) connect with fellow amateur astronomers because these connections can significantly enhance your observing program and your appreciation of the night sky.

 

Recently, I had dinner with one of my long-time astronomy friends. We were chatting about the issues he was having with his research-grade instrument and control system and about my equatorially mounted setup. We talked about how the control systems model the sky, the accuracy of pointing systems, the benefits of adding software that improves pointing, and so on.

 

I talked about my variable star photometry program (measuring the brightness of stars) and how some of my unguided images have tracking errors and had to be discarded from the image stacking process. Then, he mentioned the PEC (periodic error correction) capability of my mount and asked if I was using it. Uh, no, I haven't been. This is one of those 'duh' moments when you realize that you have a capability and you're not taking advantage of it. So, I'm going to work with my mount's PEC capability, learn it thoroughly, and see what it can do to improve tracking. Sometimes, you need a friend to remind you of the obvious.

The (Near) Future of Amateur Astronomy

Amateur astronomy is changing, again. This change is being driven by technology, the Internet, and the overwhelming amount of astronomical data now available. In the over 20 years that I've been in amateur astronomy I've seen large (often Dobsonian) telescopes come into our hands, we've seen the incorporation of computers and technology into telescope designs, and we've seen amazing advances in astrophotography.

Energize Your Astronomy

By Bill Pellerin

Do you find yourself setting up your telescope and then asking yourself, “What am I going to look at?” Or, have you missed a clear dark night because you can’t think of anything that you want to observe. I hope, in this article, to convince you that by focusing on one or more areas of astronomy and delving deep into those areas that your astronomy ‘career’ will take off. What’s more, if you do that, you will never run out of things to observe.

 

Perhaps it’s time to change how you approach your observing. If you’ve been something of an ‘astronomical tourist’ (someone who looks at objects, says, “how nice”, and moves on) and it’s time to pick your area of interest and do a deep dig into that subject. It has been my observation (pun intended) that those who are most enthusiastic about their observing program are those who really, really understand what they’re looking at and why it’s interesting. These are the same observers who have taken the time necessary to learn about the objects and who understand the object’s place in the cosmos.

Good Enough

There’s a scene in the book Huckleberry Finn in which Huck and Jim are considering boarding a wrecked boat to see if there’s anything of value to be retrieved. Jim doesn’t think it’s such a good idea and says that the pair is doing “blame well and we better leave blame well alone…”.


An observing friend of mine quoted that passage to me while considering improvements he could make to his astro-imaging setup. His setup was producing very good images and any changes might make it incrementally better but instead he wanted to concentrate on executing his imaging program with the equipment he had. Everything was working ‘blame well’ good enough for his purposes.


A more contemporary writer, Paul Simon, wrote a song that says “Everybody loves the sound of a train in the distance. Everybody thinks it’s true”. All of us think about how we could improve our observing equipment – larger telescope, better mount, better camera, better eyepieces, etc. Sometimes, though, we just chasing the train in the distance when leaving your equipment inventory ‘blame well alone’ is the right thing to do.

You Can Observe Every Night

You Can Observe Every Night

By Bill Pellerin

On December 18, 2010, the Saturday night before the full moon that became the total lunar eclipse (that I didn’t see because of the clouds) I did some visual observations of interesting stars. In particular, these were carbon stars on the new Astronomical League Carbon Stars program. I didn’t expect to see much with the sky as bright as it was, and using a 3” telescope. Most amazing to me was the fact that I was able to see all but one of the stars on my observing list for the night. That is, I could see 7 of them, but not the 8th. Not bad. The fact that the sky wasn’t totally dark meant that the brighter star patterns were easy to see and match to the star patterns on the maps on my computer.

Telescopes, not binoculars for newcomers

 

I’ve seen it said many times – ‘The best telescope for a newcomer is a pair of binoculars’. I disagree. The best telescope for a newcomer is, well, a telescope. At public star parties do the people who look through your telescope get excited about dim galaxies or about dim smudges of light? Of course not. You do, because you understand what you’re looking at.

 

The public gets excited about what they are seeing when it is nice and bright, and when you have a good story to tell about it. Saturn, Jupiter, and the Moon are the ‘wow’ objects for public star parties. After those, bright clusters (the Pleiades), a nice asterism (the coathanger) or a colorful double star (Albireo) are great public star party objects.

 

The telescope market has changed in the last few years and there are now quite a few choices of telescopes that are inexpensive. In fact you can get a 3” reflector with two eyepieces and a finder for under $50. With this, and other inexpensive telescopes the owner can see Saturn’s rings, the moons of Jupiter, the craters on the moon, and many bright nebulae and clusters.

Outreach … Sharing the Sky

Outreach… Sharing the Sky

 

By Bill Pellerin

Houston Astronomical Society

GuideStar Editor

 

Don’t miss an opportunity to share the sky with someone. It helps swell the ranks of sky watchers, increases support for our shared goal of keeping the skies dark, and it introduces the public to an activity that can become a lifelong passion. How do you get started? This short article will give you a few ideas.

 

Venues

 

You will need to find venues for sharing the sky. Some amateur astronomers have been successful doing ‘sidewalk astronomy’ events. These involve setting up their telescopes in high foot traffic areas and inviting passers-by to look through their telescopes. These usually well-lit urban environments don’t provide dark skies, but the moon, the bright planets and other bright objects can be shared.

 

Other amateur astronomers have been successful bringing telescopes to organized events, to schools, to places of worship and so on. How do you connect your volunteer group to these events?

Social Networking for Astronomers

Social Networking for Astronomers

 

By Bill Pellerin

You think that social networking on the Internet is only used by those who want to chit-chat about what they had for breakfast? Think again. Social networking covers a lot of ground and there is plenty of material that is of interest to astronomers. Think of this as a new mode of communications. We’ve had web sites and email for a while, but these communications capabilities allow astronomers, and others, to communicate with large groups of people in near real time.

 

A lot of astronomy clubs, including my home club – the Houston Astronomical Society, are working on attracting new members and are taking advantage of as many communication avenues as possible, including social networks. Professional observatories, working on public outreach as part of their mission, are also using social networking as a tool to communicate with other professionals and with the public.

 

These are great times for astronomy enthusiasts who want to keep up with what’s going on. The problem may be that there is too much information coming our way. You have to be selective about what you pay attention to. If you are a lunar and planetary observer, information on that subject may get your attention. If you are a double star observer, you will pay attention to information on that subject.
