I can say for certain in a 4.25" f/10 reflector in the late 1960s. I may have seen it in a 3" f/10 reflector as well, but my memory is not what it used to be...

I saw it pretty well in my 8" homemade scope. And last night I had it in the 12. This is in a moderately light polluted area.

Glad you brought up about the 12"...
I found that M1 was disappointingly dim and faint in my 12" when it was low (below say 30° altitude). BUT...now that it's much higher up, at 115X in the 13mm Stratus and at 150X in the 10mm SWA, it not only has a nice overall tortuous shape but there is some variegation in the shading - ie, I think I see detail. No lightning bolts like in astrophotos, but nonetheless...

From a truly dark site - 15 X 45 Canon IS binoculars.
It is usually visible in 16 X 70's from our regular observing site and almost always in 20 X 100 Miyauchis. Running the Miyauchis up to 40X improves the view dramatically.
Granted, it's not an "impressive" sight - but people seem to get a kick out of being able to say they saw it in binocs!

I've got too much light pollution to get those kinds of views. However, I'll be headed to some darker areas soon (If the weather holds) and see what I can find then. I'm looking forward to more detail. M42 last night was stunning.

Nikon SE 12x50 binocular handheld. That is just a very small fraction better than with a 60mm scope. A 12x50mm binocular due to summation is equivalent to a 59mm scope at 12x.

C8 on a resonably dark site but with lots of wind which moved the scope and affected seeing. I'll be trying again later with my C11 from my backyard.

I'm glad to see this question since it took me four tries to see M1 in my SVP127 Mak. It's an "M" it should be easy! Argh! Of course the first three tries I had less than ideal conditions for nebula. I got it last Thrusday and it's suppose to be clear and dark this coming Thursday so I'm going after a better view.
I admit I'm a newbie but other than Orion...this nebula stuff is tough!

I have tried and tried and tried to view M1 from my backyard with every instrument I have and failed, miserably.
25x100 binos, 15x70 binos, 8x42 binos (didn't expect to see it with these although I heard it is possible with dark skies), and 60mm refractor at ~28x,56x, and 70x.
My average NELM is ~4.4, so it's not surprising that I failed. And FWIW, I am sure I am looking in the exact place with the help of my atlas and Starry Nights. The sky is just too washed out.
I know, this thread was for those who actually SAW it, but seeing as how I have spent tens of hours (literally) behind the eyepieces hunting for this elusive object, I feel my frustration qualifies me to answer anyway!
M1 is first on my list of objects to bag the next time I get out to a dark sky site.

I have seen the Crab quite easily in a 15X80 finder. But, that was during an Arizona night that I rated 8 out of 10 for transparency, so that might be "no fair".

I'd glimpsed the Crab in averted vision in an ETX-125 with a 32mm eyepiece. This was last December, with the headache of an 11 day-old Moon in the area, near Mars.
On moonless nights (ZLM 5.2), the Crab is easily found as a rather faint bean-shaped haze in the same scope.

I don't remember the smallest, but the largest was a filtered 24" Obsession and I could see some of the tendrils clearly with that setup. Looked like a photo!
