I'm heading up to Scotland in April for a bit of a road trip and I'd like to give astrophotography a bit of a go. I'm like to try and get some deep sky photos (Andromeda etc) and have decided that rather committing to an expensive tracking mount, I'd just spend a small amount and give a barn door tracker a try.
I'm following this guide: https://barn-door-tracker.co.uk/
It nearly all makes sense but I'm a bit unsure about the polar alignment. I'm thinking I'll get a laser pointer as the above article suggests but I'm not really sure how to A) attach it to the wood (should it be attached to the top plank?) and B) does it matter how far from the bit of wood it sits? Does it have to be right on top of the hinge or does it not matter?
I was thinking of getting a mount like this: https://www.amazon.co.uk/EBTOOLS-Adjustable-Astronomical-Telescope-Aluminum-default/dp/B07MN54WCW/
Any advice would be super. Thank you!
