Pretty well all my images are unguided usually between 30 to 40 seconds. Have a look in the beginner section and you will see a couple on the first couple of pages. The Orion image was 1000mm fl but the others are 400 mm fl. I star out to use auto guide but usually end up abandoning it and fall back to 30 sec unguided subs...do a couple of hundred and stack etc
