The future of observing..?

A night under the stars with Clear Skies Observing Guides.CSOG, short for Clear Skies Observing Guides is a digital publication. The first to allow observers to target all deepsky objects and carbon stars in reach of their equipment. From 5 inch scopes up to telescopes with 12 inches of aperture. CSOG contains thousands of objects, including all Herschel objects, all DSO's in Burnham's Celestial Handbook, Arp, Hickson and many more.

CSOG is a combination of observing guides and software. The guides, containing relevant, up to date information and a description of the surrounding starfield, are intended to primarily be used on a tablet at the telescope's eyepiece. A DSS images is included for every object.

Matching tours for Meade's Autostar controllers, NexTours for Celestron's NexRemote, EQTours for use with EQMOD and Argo Navis User Catalogs allow GOTO telescope users to target thousands of objects with ease. Matching AstroPlanner planfiles make planning of observations a breeze. CSOG allows you to target objects you never observed before, in many categories, night after night. Beyond the NGC & IC, off the beaten track. CSOG is unique, new and very complete.

The future of observing is here.

Not another starchart, not another armchair astronomy book

Books on amateur astronomy are as numerous as the stars, as are maps of the sky. CSOG is neither. It's not a starchart. It's not a book. CSOG is a concept.
In CSOG the mechanics of the sky are not explained. There is no analysis of stellar spectra. There are no endless tables filled with object names and a few abbreviations, sorted only by right ascension, leaving you guessing whether or not an objects is in reach of your telescope. There are no sketches or esthetically pleasing but unuseful images. CSOG is not a book, it is something different. It takes out the guesswork and will not leave you in the dark.

How the Clear Skies Observing Guides stand out

  • CSOG is truly all sky, covering all of the 88 constellations.
  • It is a digital publication intended to primarily be used on a tablet at the telescope's eyepiece.
  • It is the first publication to:
    • - list all DSO's and carbon stars visible in telescopes up to 12 inches in aperture, in detail (>14000 objects)
    • - provide a complete list of carbon stars up to mag. 11
    • - use an ergonomic "observing card" style layout in a dedicated dark color scheme, perfect for use on tablets
    • - list object synonyms, not just the most commonly used designation
    • - clearly list useful information: classification, magnitude, size, position angle, etc.
    • - include a DSS image for every object, uniformly scaled, uncompressed and with a known scale and orientation: a "standard candle" for visual astronomy
    • - be available in editions with mirrored or unmirrored images to best match the view in your eyepiece
    • - contain a field description for each object, with bearing and distance to stars and objects in the vicinity
    • - sort objects not purely in R.A. (right ascension) but in an order that minimizes the distance between them, using "blocks of declination" where required
    • - include matching tourfiles for Meade Autostar, Celestron NexRemote and EQMOD, Argo Navis User Catalogs and AstroPlanner planfiles
    • - be available in Constellation Editions by telescope aperture and well known catalogues and lists: Messier, Lacaille, Dunlop, Herschel 400, Herschel II, Herschel, Hickson Compact Galaxy Groups, Arp Peculiar Galaxies, Holmberg galaxies, Dolidze, Dolidze-Dzimselejsvili and Stock open clusters, Palomar and Terzan globular clusters, Caldwell and Bennett.
