Logging Time behind the Eyepiece new
      #5360969 - 08/10/12 12:46 AM

One regret I have after being actively involved in astronomy (at a club level) for 33 years and with a total of 51 years with a telescope since that first 60 mm refractor at age 9 is the fact that I have not kept an observing log.

In spite of all those years my actual time out with all the many telescopes I have owned actually has to be relatively modest compared to some. Partially due to my own laziness, bad south Louisiana observing weather and other life distractions. So how much time have I spent actually observing and using my telescopes? I'll never really know but I have attempted to take an educated guess.

What I did was list scopes that I have had and/or still currently own; and then add to that years of ownership and take a crude educated guess at what my likes were in those years, factoring in how much time I spend observing from home and from dark sky sites, out reach events and organized star parties. I then reduced my hourly count for each telescope by about 1/3rd in recognition that my bias was probably liberally giving myself credit for hours that were not there.

I won't list all of the scopes that I have owned but here listed are the major ones ranked by total "realistic" hours of use, at least I think -

Vernonscope Brandon 94 mm - 650 hours of use between 1992 and 2006

Jaegers 6" f/5 - 450 hours of use between 1979 to the present

Meade 2080 Schmidt-Cass - 200 hours of use between 1982 and 1987

Unitron 4" f/15 refractor - 150 hours of use between 1986 and 2002

Brandon 130 f/8 apo triplet - 120 hours of use between 1992 and 2004

Intes 67 150mm f/12 Mak - 80 hours of use between 2001 and 2007

Orion 100 ED - 40 hours of use between 2004 and 2007

Takahashi TSA 102 - 40 hours of use between 2007 and 2012

In addition there is probably another 700 hours spread among various other scopes ranging in size from 50mm f/12 refractors up to a Celestron 9.25 SC, plus another 500 or so hours with binoculars including about 100 or so hours behind the eyepieces of a pair of 100mm Miyauchi binoculars.

Note, these are all scopes that I either own or have owned. Additional time spent looking thru the eyepiece of other people's scopes.

I know too that the time I have spent has to be quite modest compared to some. I have about 2930 hours between 1979 and present. This is only about 90 hours per year; I am sure some of you log 90 hours per month. Anyone else have a good idea as to how many hours you have in your "Celestial Flight Log"?

Fortunately/Unfortunately I'm the same as you (not in time, I don't keep a log). I've not logged a lot in the last year, maybe 20 actual viewing hours since April (weather mostly). Maybe because I don't get a lot of viewing time is why I don't keep a log or sketch. Actually I don't sketch because I can't draw a straight line. When I am out, I'd rather be viewing. The other night I was out for about 3 hours and only viewed about 4 objects. I usually spend time viewing an object rather then seeing how fast I can put an object in view before going onto the next one. I've never felt it to be a contest; there's more out there then I can possibly see in one lifetime, so I'll enjoy seeing the ones I do. One nice thing about astronomy, you can always go back for another look......

I've always kept a log; not that I won't go back & enjoy those targets I've already logged, but it's interesting to read what you "saw" previously, compared to the present. I've also gotten interested in sketching my views, so again, it's an interesting record of my progress.

For those that are interested in pursuing the various Observing Certificates, a log is a must.

I have never kept a log of observations as for me that would take all of the fun out of astronomy.

I do my reading and writing when compiling my observing list for the upcoming session. It can take hours looking at photos and reports of the intended objects, giving me insight as to what to look for when at the eyepiece. When at the dark site I spend my time at the eyepiece, with the PSA or talking with like minded people.

I think some of you have missed the point of what information I was trying to get via my first post on this thread. It is not so much about the pros and cons of keeping an observing log of celestial objects seen but more a record of some kind as to just how many "star hours" are on your telescopes. Certainly an observing log would do that nicely. I regret that I have not kept one for that purpose in addition to a log being a good chronicle of what I have seen and what my impressions are of the objects in the night sky.

My major curiosity remains just how much are telescopes used - hours under the stars. My inventory of telescopes and their use is based upon memory mostly and maybe fuzzy memory. What about you, I am sure there are some out there that have bettered 2000, 3000 or even more hours behind the eyepiece of some of their telescopes. This is what I was interested in learning more about.

I try to get out with my scopes as much as I can, but recently, it is only about one or two nights per month (at least for deep-sky viewing). However, if that night is halfway decent, I will generally spend from two to as long as seven hours at the scope. Indeed, on the best night of the Nebraska Star Party in July of this year, I had my scope out from dusk to near dawn (10:30 p.m. to 4:30 a.m. at that time of the year). As a rough guess, I suppose I might spend from 60 to 80 hours per year at the telescope (not counting time viewing the sun in the daytime with my PST or my outreach hours with the public), so it isn't all that extensive. Still, it is time well spent. Clear skies to you.

Sorry for the misunderstanding. I've only been observing since 2005, and yes my logs do have the times spent; however, I've never gone back and added up the total time spent at my scopes.

I've never really kept track of time spent... In my log, I usually put down the time I started, but after that, I just ramble. Some years, I'd rack up a fair number of hours, others very few. If I logged naked eye time under the stars, it would probably be pretty impressive. Time spent with optics, not so much. The amount of time just doesn't really matter to me.

I can see how this information would have been interesting and helpful to you. In my case, I knew I would not have ever needed or wanted this type of information. One time I did want a log comparing a 6mm Delos, 6mm Radian and 12mm Nagler with a 2X Powermate. I took a small digital recording device and recorded my observations. That's a handy way to so gather information rather than trying to write things down when viewing.

Barry,
After I moved to SoCal, where to do observing requires long drives to mountain or desert sites, my observing has been confined to one or two all nighters a month, or perhaps 8-18 hours a month depending on season, or 100-180 hours per year.

Nonetheless, I started keeping a log in 1982 when I had a 6" scope. At first, the log was a way of telling me what objects I wasn't interested in re-visiting.
Upon obtaining an 8" scope in 1993 and thinking it would be my "lifetime scope", I started keepin a a log in earnest. My goal was to see everything visible in an 8" in my lifetime. I prepared a list of about 20,000 objects I thought MIGHT be visible in an 8" under the darkest skies at my site.
I had just under 9300 objects in my log in 2004 when I upgraded to a 12.5" dob but I had barely dipped into UMA/CVN/COM/VIR/HYA galaxy groupings. A lot of those objects were tiny little galaxies and not particularly fascinating, but there were literally thousands I hadn't viewed.

I quickly realized that the number of objects visible in a 12.5" dob would be larger than I could view in a lifetime (in excess of 30,000 objects, for sure). So the idea of logging every object visible in the scope went out the window. Instead, I decided to concentrate on particular constellations to see how many non-viewed objects I could view. Today, my log has barely passed 11,000 objects, so I have not been systematic about logging new objects. I spend a lot of time with old favorites or pursuing an object that's eluded me for years or getting sidetracked looking for details in an object, even though I've looked at it before.

And for the last couple years, I've been concentrating on creating a list of the 500 best DSOs for beginners moving beyond the Messiers (you can send me you email in a private message and I'll send it along). I think I viewed many of those objects for the first time in decades and "rediscovered" some very nice objects. Along the way, I got sidetracked viewing Hickson groups, PK planetaries, Abell planetaries, carbon stars, etc, so it's been good for my observing.

I still have quite a number of objects in my printed list that I have yet to view, and the thing that keeps me looking for new objects is that out of every 25-30 new objects I view for the first time, I find one that is REALLY nice and would be added to my "Favorites! Revisit! Nice!" list of really interesting objects I was formerly unaware of. The idea that there might be something I've never seen that would impress me as a spectacular or very interesting object keeps me looking at new objects I've never seen.

Maybe some day I'll get to the point where every object not yet viewed is a tiny galaxy 350 million light years away and more, but before that happens, I'll probably be long gone.

So don't feel bad, ever, about not spending enough time with the hobby--it's about quality, not quantity.
One of the things you can do to enhance your observing skills is to try sketching the objects you view. Trying to fill in small faint details will help you see more. I refer you to the drawings here on CN by Eric Graff (Cildarith) and Jeremy Perez to see what can be ferreted out in smaller scopes. It's amazing.

And I attach the observing log page I use. If you answer all the questions, you will have a fairly complete observation. Sometimes I forget to use the log and sometimes I forget to record an important feature in my observations. That's an excuse to go back, eh?

Don,

I'm enjoying your list of 500. It's ideal for someone transitioning from beginner to intermediate. I could probably be accused of logging too many hours simply revisiting the well-known favorites of deep-sky over and over again. But when I get a hankering to visit something new, your list is real handy and they have been rewarding sights, so far.

For users of SkyTools 3, I believe it is Don's list that has already been made available for download into the program and to be found under the Deep Sky list heading. It's listed there as the "Pensack 500". So Don, to the extent that you've played a role in getting that list ready for us SkyToolers, we thank you.

Branching out this way is proving to be great way to get more observing satisfaction out of each observing hour.
