New Publication: Clear Skies Observing Guides
Posted 20 October 2012 - 05:23 AM
CSOG is a new digital astronomy publication.
Observing guides for thousands of DSO's and hundreds of carbon stars, covering all 88 constellations. Matching tours for Meade's Autostar, NexTours for use with Celestron's NexRemote, EQTours for use with EQMOD and matching planfiles for AstroPlanner. CSOG goes off the beaten track, beyond the NGC & IC, and into the Magellanic Clouds.
CSOG is available in constellation editions for three telescope aperture classes (5-6", 8-10" and 12") and in either an all-sky edition of by northern or southern hemisphere.
The 8-10" edition contains all of the DSO's in Burnham's Celestial Handbook, and more. In the 12" all-sky edition the number of DSO's in BCH is septupled.
In addition there are "Specials" for well known catalogues.
Read all about it on the Clear Skies website.
For Cloudy Nights forum members there is an introductory discount. Using the code CSOG-CN25# you will get a 25% discount on your purchase. This code is available ten (10) times, on a first come, first serve basis.
Wishing you all Clear Skies !

Total content: 5.99 GB
Total Folders: 385
Total Files: 1810
The PDFs are really well done and are going to be a great resource. Because PDF files are vector based, you can upscale them to 600% or more to look at detail on the images of each object. These should be great on Apple or Android tablets.
The file unzips into a main index file and folders based on each constellation. Subfolders contain the tours for AutoStar, NexStar and EQ. The main folder also contains a separate constellation index and one file each for galaxies, planetaries and nebulas within that constellation. It's a huge amount of information and I love the "observing card" style presentation for each object.
Now, I just have to figure out how to incorporate these guides into my observing. It's too good not to use.

attempted to unzip - got error - "Error: central directory not found."
Sorry to hear the file does not unzip (yet). I assume you use Windows (7)? Windows can give some trouble when it comes to unzipping large files... Can you please give the application WinRAR a try? Download link: http://www.rarlab.com/download.htm
Let me know how it works for you!

Yes, there are plenty of files in the edition you got, and that's "just" the 5-6" Northern one..!
I hope you get a chance to use the guides and tours soon.
All you need is clear skies now.
All the best,

Next question... What are the APD files?

I did use it on the Veil Nebula though and for the first time in my 3 year astro 'career' I managed to positively identify the different filaments. And I saw some additional ones as well thanks to the DSS images.
