I'm hoping someone here might be able to help.
I'm doing some research before I get out and start doing some astrophotography. I've been reading up on FOV and searched astrobin and forums and I think I'm pretty dialed in for what to expect and I'm going to go down the DSLR/lens route (35mm/200mm vintage and a more modern 14mm).
In terms of mounts I think a star tracker would be the best option due to the portability of the system (if I decide to use heavier equipment, then I'll need to get a proper mount, but I'll still be able to use the tracker as a portable setup).
I've been looking at the Sky Watcher AZ-GTi in equatorial mode and it looks very flexible due to the goto and portability. My only concern is that it doesn't have a polar alignment scope. I see that polar aignment is possible, however it seems to be largely a guidescope based solution or require a laptop.
Is it possible to do polar align a AZGTI without a guidescope, using the DSLR? Ideally (to keep it portable) through a phone app or similar. I've seen the ASAIR plus, but that looks very expensive. I've also seen the Astropi which looks like it might work through the DSLR. If anyone has experience with these options, or even just getting a good polar alignment in the field with it without a lot of equipment I'd be grateful.
Many thanks,
Graham
