Hi Dave!

Great to see you here again

Following on from Jameson's point of a reticle eyepiece, and a fantastic alternative to these, I use a high power eyepiece and de-focus the star's image so that it appears a HUGE donut (or disc in the case of refractors) so that it almost fills the whole field of view. This donut is not only much easier to centre, but also extremely accurate. EPs with ultrawide AFOV are not the best for this, but modest plossls or other EPs with no more than a 60° AFOV are excellent. I use this method with my push-to dobs and my EQ6 mount.

Alex.

PS - as Jameson also says, Sky Safari is EXCELLENT for locating named stars! Even though I've been doing astro for more than 35 years, the names of all those wee little stars is not one of my strengths... So Sky Safari is a great tool to help me identify named stars and locate them in the sky. Makes things very much easier!

Alex.
