Re: 2-3 Star Alignment #iEXOS-100 #ExploreStars #alignment #sharpcap


Thank you Jerry for the input. That was a question I had about locking onto the brightest star in my FOV with my 50mm guidescope. I will give that a try tonight.

I have been having trouble performing a 2 or 3 star alignment, meaning I am not 100% sure I've locked into the correct star, so I usually take my best guess.
Hi Tommy,

The Explore Stars 2 or 3-star "virtual polar alignment" system is designed to make it as easy as possible (within reason) for beginners to get a good alignment so that the GOTO navigation (Pointing) to stars is accurate. The default setting is to slew automatically to the first suggested star when selecting 2 or 3-star alignment. If you have set up your tripod and mount to have a good physical polar alignment (within a couple of degrees), then with a wide field finder the slew will take you to the alignment star and you should be able to identify it as the brightest star near the center of your finder. If it is behind an obstruction, then just hit NEXT to go to the next suggested star.  It should not be hard to identify the correct star as Explore Stars will show you which star in the constellation it is pointed to. 

There is the option to turn off the "Auto Slew" function so that you can select your stars without the mount slewing to every star in the list until you get to the one(s) you are after.

This is how it is designed to work for beginners.  I hope this helps to understand.
