I just looovvveeee my 8" f/4 dobbie - I can get a massive 2.5deg FOV using my 30mm TMB Paragon. A bit big in exit pupil, but I can live with that. And now that she's got legs, I can comfortably sit in a chair and use her, rather than be on my knees.
Here is my WIDE FIELD attempt over the weekend. With this 8" beastie I am able to capture within the whole FOV M8, M20 and squeeze in M21. On their own each DSO is gorgeous. Together, WOW, what a collection.
It was done from home in Sydney with conditions being ok. A couple of nights previous the dark lanes in M20 were much clearer to make out. This night not so well, and I didn't want to include them as I just couldn't get their direction and shape, only a faint hint.
I also did notice some faint nebulosity to the right of M8 in the "void" between it and M20. Soft and amorphous. This will be quite a vista from a dark site.
