This challenge comes from the comments. What if you can't use a computer to control your mount? How to manually polar align a Celestron NexStar 6SE / 8SE mount using the hand controller with enough accuracy for astrophotography WITHOUT guiding. I use an ASI294MC Pro camera with APT, but the same process applies for DSLRs, although with an added difficulty modifier for viewing star trails on a small LCD screen. #astrophotography #celestron #nexstar #wedge

As proof of concept, I'm imaging Globular Cluster M15.

UPDATE: THERE **IS** AN OPTION TO DO A POLAR ALIGNMENT USING A HAND CONTROLLER ON THE NEXSTAR MOUNT: i.e. the hand-controller version of performing an ASPA. It is poorly documented, and the NexStar mount instructions that came with the scope, the wedge, or the ones available online certainly did not cover it properly. However there is a document that covers this on Celestron's knowledge base:

I still think that you would need to do a manual drift alignment in order to properly orient the scope for better guiding, but performing the Polar Alignment would definitely help to bring your scope closer to where it should be thereby reducing the effort to drift align (similar to using ASPA with CPWI).

Thanks for watching, and clear skies!
