Periodically all the segments of the display turn on, rendering it useless. No operation of the 3 controls restored the display. I normally use NiMH batteries, but when this happens I have tried alkaline and also a 12v external supply without success. Normal operation returns randomly. Sometimes an hour or several days pass before operation returns. I once got quick restoration of service by switching the unit off and on rapidly. Recently, tapping or slapping the sides of the unit has returned the display to normal. But this cannot be good long term.

My search of the forums yielded no results. Does anyone have suggestions or solutions(s)?

I have spent quite a bit of time trying to figure out various star catalogs, with not much success. It seeems there are more star catalogs than stars I'm interested in. With a lot of work I have been able to find most of my 30 favorite stars spread through the 3 AN star catalogs.

I have tried Argonaut to see if I couldd see the listings in the catalogs, apparently that won't work. I realize that at almost 10k stars, a listing could be onerous.

I have downloaded the 5 Struve catalogs. They have STXX designations. I thought the common designation for Struve was the upper case sigma letter. Some clarification or a guide for the designations used by AN could be most helpful.

2 examples of my frustration would be La Superba, and VY Canis Major.

Other than this I have found AN very useful, and amazingly sophisticated. I'm sure the star catalogs are every bit as sophisticated, too sophisticated for me to make full use.

Regard to all interested, Steve
