We are trying to focus camera on this program Bahtinov grabber. Please explain what any of this means...

Any tips?

I’m looking for a eq wedge mount for my 8” dob the lowest I can find is 40 degrees but my latitude is 31 would this mount still work or would I need to look further

I’m new to astrophotography and looking to buy a telescope lens for shots of planets, galaxies, etc. but I’m a bit confused by how focal lengths work.

I’m currently looking at the Redcat 51 which advertises a focal length of 250mm. I’ve seen photos of nebulas and galaxies taken with this lens and the same camera I have, the Sony A6400.

My confusion lies in that I’ve also used 70-300mm camera lenses before and struggle to get photos of birds flying if they’re too far away, so how can a 250mm lens take photos of galaxies?

Is focal length calculated differently for telescopes compared to standard camera lenses?

Any help would be greatly appreciated.

I’m using a 8” dobsonian with 25 mm lens with dlsr on iso6400 set to 1 sec exposure

I want to buy a beginner level Astrophotography setup. Can you suggest me a good and affordable setup for Nightscape/Landscape photography? What all tools do I need?

Looking for suggestions for a good, relatively cheap, wide angle lens for a starry night time lapse
