A small irony.

It's just struck me that most of the mosaics we do here are with the short focal length setup which already has the widest field. The same can be for most other mosaic makers on SGL. Interesting...

Well I have got a WIP NB of NGC7000 / Pelican using 10"SCT and Atik 314L that I occasionally catch a few more subs for when the mood takes me, probably never get finished

So, if you'd do a mosaic with your longest fl, would you "just" stitch together one target (eg M31), or go for a super wide field with dozens of frames, getting maybe most of Cygnus? Would there be a benefit using a long fl over a shorter one?

If I ever finish mine I'll let you know

Since you mention M31, I have a (very) long term and occasional project, just purely out of sheer interest. M31 was the first ever object i imaged and processed entirely by myself so it has a special place for me. I think i am just curious as to what the additional resolution will give, and hopefully some improved processing.

Trouble is, at 1200mm and a 8300 chip, it is 35 frames with 10% overlap to cover the galaxy and have a decent border. My original effort attached. I could be long forgotten before this one gets done .

I started mosaics with a longer FL scope, but soon decided that a wider setup was just the job, but then, as always there is that interesting bit just poking in to the top left corner which requires not one frame but a whole row, and yes there is another interesting bit just coming into sight!!!!!.

This is where the amature comes in to their own, I think we produce the most detailed wide field images out there.

Heroic! Jonas Grinde did a big one on M31 as well.
