Basically I said, believe what you see, not what you hear. There was more but...

I'm working on the H400 at the moment, almost half way there. And from my fairly dark sight and an 8" dob I've been able to find everything pretty easily thus far with one exception.

This is great example of the importance of good seeing and transparency. On a night when conditions seemed to be fairly good but not great I went in search of NGC 2158, an open cluster in Gemini which should not have been that difficult. I star hopped in and there it wasn't. I confirmed I was in the right spot but couldn't find it. I must have spent 10 minutes waiting for my eyes to catch it. Nope. Looked at a few other things but pretty quickly realized that though there were no obvious clouds the humidity had risen and I was seeing less and less by the minute.

I went out the next night and looked for it first thing. There it was. I found it instantly. I learned from this to never underestimate what poor seeing and transparency can do to limit what I can see. Also, never underestimate how quickly fairly good conditions can deteriorate!

I am working on sketching each of the Messier objects and have been able to get some really nice detail on quite a few.


Sketching is a great way to develop your observing skills and build a lasting & personal record of your observations. Enjoy the night sky.

Thanks Denny I will take this into consideration. I see you are doing a few at once. I never thought about it that way. Thanks for your feedback

Bill,
I bought a hard cover sketch book and started sketching a writing details about the temp, wind, eyepiece, and seeing about a month ago. When I go back to look its very interesting. I also wrote about the Geminid Meteor shower what we saw and my daughters reaction. If anything we can have a laugh a few years from now.

You're welcome.

Wow. Thanks (anyway). What a great collection, and especially the first site linked to, which has so many other lists under one roof

Cheers

Hmm, my "You're Welcome" was meant for Ken.

Again thank all of you for your input and expertise.

Yes Dave,

And my "anyway" was to acknowledge that, and to appropriate yer "You're welcome" for my own thanks for the great links you provided. Sorry for the confusion.

Dave,
The lists you sent are really quite amazing. I am still trying to digest them. Great information. I didn't quite realize the depth of them when I first responded. I tried for m77 last night with no luck. I have a long way to go!

Thanks again. Happy New Year and clear skies.

Thanks again. I am going to look for the brighter objects, since they will be easier to start with. I will wait to try the dimmer ones when I get in darker skies and get some more experience.

I think that I especially like Vic's, for his inclusion of the skies in which he nabbed his targets. Most encouragin to we who suffer under suburban skies.

And the more I look, the more I like the last one,

http://www.1000plus.com/

Now THAT'S what I call a personal website. Are they active here? :drool5:

Thru his links, there's this...Sky View, The Internet's Virtual Telescope, offerin 5 different spectra by which to see yer favorite targets

http://skyview.gsfc.nasa.gov/

or The Cosmos in Your Pocket: How Cosmological Science Became Earth Technology

http://arxiv.org/abs/0710.0671

or this, The Impact of Recent Advances in Laboratory Astrophysics on our Understanding of the Cosmos

http://arxiv.org/abs/1112.2770

or Introduction to relativistic astrophysics and
cosmology through Maple

and so on and so forth. Nice job.

I think the more I dig into the list the more I find. Now I just need a cloud filter I have had one semi clear night in about 10. Not looking to good tonight either. I need to come up with a list of brightest to start with.

Thanks for more links.
