I would highly recommend SkyTools 2 software for its superb logbook feature.An observing log entry should contain observers name,date,location,instrument and...
Big aperture matters mainly for DSOs. Once you get above maybe 12" (highly variable from night to night, and depending on your location), fine resolution is...
Hi Alvin, Do you mind if I ask how much more or better are DSO with a 30" Vs a 22"? Thanks, ... From: bigdob@yahoogroups.com [mailto:bigdob@yahoogroups.com]On...
There's a huge difference with DSOs between a ~20-inch and ~30-inch. Assuming you scale the f/ratio's between the scopes equally, just the image scale will...
Things that I record: Object name (both designated name ie., NGC9999 and common name) Date and time of observation Location observed from (regular name ie.,...
John, My experiences have not born out the big aperture for DSO's theory. I have owned a bunch of high-quality larger aperture Newts from 12.5" to 24". My best...
It happens, but it's very rare. Our 16" outperforms our 12" on planets maybe once a year. It's a real treat when it happens, but I wouldn't buy a very large...
John, Given your findings, I would imagine that it must be location dependent to a large degree. Almost all of my viewing has either been in South Carolina or...
Florida is famous for good seeing. I'm in the midwest where summer air is warm and humid, so it cools slowly at night (minimizes thermal turbulence, and...
John, I was 8 miles from the Atlantic ocean. I am now about 35 miles from the Gulf of Mexico in North Florida. Chiefland where I like to do dark sky observing...
... Bob... I've seen conditions deteriorate, here in Florida, since I moved here 15 years ago. Not just light pollution (although my home site has gone from a...
Peter, Generally, I see about a magnitude deeper. For the stuff I look for, 18 and 19th magnitude galaxies becomes threshold objects, while 17 and 18 or...
Hi Michelle, My son is the "Excel" expert and he helped me format it so that I can copy log entry to clipboard and then paste it into an Excel spreadsheet.I...
For those who might be interested in imaging with a Dob. Michelle Stone asked me if I had imaged any dim stuff, so I gave it some thought and tried Hickson...
Great shot, Dan! How about some really dim globulars like the Terzon's or the ESO's? Scott ... For those who might be interested in imaging with a Dob....
Thank you for the suggestions, Scott! I'll check them out. Dan ... From: s.kranz1@... To: bigdob@yahoogroups.com Sent: Wednesday, June 01, 2005 12:41...
I have seen 4 of the 5 components visually in my 30 - compared to a 25" Obsession at the same time (a customer here using our facility) and I could not see any...
Alvin, If you are considering a 28" Kennedy I have a 28" F4.15 (115.5" Zenith) that will be finished this weekend. If I recall the 30" F4.3 had a 129" Zenith....
A few years back someone with a 30 SM made the comment on one of these groups that he had modified his scope to allow the mirror to be transported in the...

... I started using the log features in Starry Nights software and there are certain advantages to it - but then I switched to just using MS Word because I...
Greg... Great explaination of what exactly it is we should record. It brings up an interesting point about the methodology: I could record by object or by...
"SkyTools 2" has a log browser which solves this nicely. You can search for logs for object, object class (galaxies, comets, ..), date, observer, location,...
Yeah...it's available electronically, but the problem is that it requires double work or carrying an electronic device around, which is cumbersome. So, I guess...
Greg makes some good notes as to what sort of thing you could record. I also use a voice recorder and highly recommend doing so. I tried Starry Night Pro 5...
... I also use ... On the voice recorder, I would add that I find having it date and time stamp most useful and searched around quite a bit until I found a...
Greg, Forgive me for not following this thread too closely. I have always thought the best way, at least for myself, to log is with a voice recorder but I...
