Crab Nebula with a 3" Telescope?


M Astronomy

Recommended Posts

Hey, I am wondering if anyone knows if it is possible to observe the crab nebula (m1) with a 3 inch telescope. I live in a rural area, so light pollution isn't an issue. I would really appreciate it if someone replied before tonight, as it's looking really clear and I am hoping to get my telescope out. Thanks!

Best of luck with M1.  It took me ages before i saw it, and the first view i had was with a 3" - a 90 Mak.  As said, although it's just a smudge, it's still amazing !  Try a lowish magnification, perhaps around 30x  as too high and it might blend into the background, and wait until it's higher up in the sky.

Easily seen and enjoyed with my 3 inch from a rural location, as I've come to appreciate; it gets better the more times you observe it and become familiar with it..(think that applies to many targets).

Good hunting.

Wow ! - you must have a really dark back garden Pat :thumbright:

What size small binoculars are we taking about ?

Old Messier himself wasn't using a great big scope when he cataloged what we now know as the Messier Objects. Of course he wasn't contending with sodium-vapor streetlights and massive city-glow polluting our skies. So aperture-wise, your fine - light is your (our) bane.

ps - The Messier Objects were a list of things to avoid, as they could be mistaken for comets - as comets were what he was actually looking to find!

You will need a dark sky. Last I looked at it was in a 6" and I said I could see something the other person said she couldn't and doubted my honesty. There was a fair amount of light pollution, but would still be more a borderline object I think.

When first seen the shape observed did not match the one we are familiar with today, simply the scope was poor. Crab relates to the initial shape, which from the distant memory of it it seemed more lobster like. So yes Messiers scope was not big, but it was also not good.

Here's a very nice, graphic software-program to help you find & view the Messier Objects. It's Free as well:

If you like it (I have a copy on my desktop), here's some others from David Paul Green, who put these together for you:

I like the pictures in this. Hope you enjoy!

FWIW I've seen it in 8x50s one very dark and clear night, when it was high overhead.

I had a reasonably good dark night tonight (mag 5.5 visual) and struggled to see any more than a suggestion of M1 with my Opticron 11x70 binoculars.

It was just the once! And I was twenty younger than I am now. I'll keep a watch this coming winter and see if I can repeat the feat.

If memory serves me right, I've seen it in 15x50 Canon binoculars from a dark site on the Purbeck peninsula in Dorset. I think dark skies are as important as anything else with this one.

Interested to know how you're getting on? As above in a rural area you should catch M1 with a 3" scope. I found it as a small faint blotch in 10x50 binos on a dark night, visible in averted vision much of the time (but blinking in and out to be honest). M101 by contrast was harder for me and only fleetingly visible although when it did pop out I could see the orientation. I should add that from exactly the same spot I've missed M1 in a 10" scope even on what seemed to be a good night - transparency and darkness as important as ever. Good luck!

Hey! Thanks for all the support. Its been horrible weather recently and I have been unable to observe much (though I did manage to see the taurid meteor shower a few days ago). I will keep trying until I find it. 

Right now I am saving up to buy a Skywatcher 200p on an EQ5 mount, which should give me some great views. Does anyone know what I should expect to see of the crab nebula with an 8 inch scope?
