Sweet reminder

LT_5

Hi,

I know there are some folks here preparing for their astronomy trip to Taiwan in the coming holidays. For those using Vixen mounts, please be reminded to calibrate the longitude value of your polarscope. Almost all the places in Taiwan are located at longitude value > 120 degrees. So, please use a GPS or check for the coordinates of your observation spot with a map. Then offset the longitude dial to a value = longitude difference E (east) of the marking (120* default value), if you want to have a maximum imaging time for unguided exposure.

Hope it helpful to you.
