ASCs

Alignment Star Charts ASCs are star charts made to assist you in aligning your computerized GoTo telescope. While they are all based on one of two template star charts that display from 60 to -60 degrees declination, the alignment stars are labeled by the same name that is used in the telescope's computer. Where a star chart has two names, those computers share the same list. With the advent of the CG-5/CGE chart, we have gone to an "abbreviated" ASC. These two GoTo scope use a database of alignment stars that includes many 3rd, 4th, and some 5th magnitude stars. While this is laudable, it gives a database of 250 named stars. To simplify the chart, only stars of brighter than 3rd magnitude stars are shown as these are the stars most likely to be used. The chart for these telescopes contains about 130 stars and is quite acceptable for aligning these scopes. All of these charts are on 8.5"x11" paper and can be bound into the Telrad Finder Charts which are the same format.
Here are two samples of our star charts. The second ( for scopes that use many more alignment stars) has half of the chart on each side of a page to provide room for more stars.
Format 1: For scopes with 20-100 alignment Stars	Format 2: (both sides of sheet) for scopes with 100-200 alignment stars. Hash marks at each hour RA.
ASCs are available for many GoTo telescopes. If you have one not on the list and wish to have one made, email me at johnduchek@duchekconsult.com. I am happy to make one up for most systems out there. I will need from you a list of the alignment stars for your system. Sometimes the manufacturer can send you one. Alternatively you can write the list while scrolling through the alignment stars on your computer. Note: If you purchase an ASC at the same time as one of our Telrad Finder Charts, the ASC or other star chart can be bound in as the last page of the book at no charge. Just request it!
