Re: [Utah-astronomy] RASC Colorful Doubles (N=79) to SAO Cross-reference list

Not at all. I've used it for one season on my ETX 125 at home and part of a season at a UofU Physics Meade LX200. In a light polluted environment, using a cross-reference list to SAO is indispensible and is superior to slewing by inputing coordinates. If you first synch your scope to a nearby bright star before slewing to the final SAO double destination, it pretty much hits the double right on every time, even in the mini 1/3 degree LX200 TFOV under light polluted skies, except for catalogue cross-reference errors. - Kurt P.S. - Please also note my Oct 2010 posted table for a general LX200 Meade Handbox to SAO stellar cross-reference list - Table: Cross-reference Bayer-Flamsteed-to-SAO for 1822 stars brighter than mag 5.5 visible above -40° dec http://fisherka.csolutionshosting.net/astronote/plan/mansetcir/html/LX200SAO...
I guess I just am not used to using goto, I have many doubles logged in my Tirion Atlas and I have never bothered to log the SAO designations. Without an atlas I have many in memory and the names I remember them by are not SAO designations. It is generally easier not to bother with goto unless the scope is hard to move manually (the Grim). I mainly use coordinates, with Tirion, to verify I am looking at the star I want to, along with Sissy Haas's book.
Thanks for the cross-referenced list though, I will try it. Erik wrote:
