M51 Where Are You

I spent a good 20 minutes hunting for M51 last night, to no avail. (TV102 with a 32mm and 26mm plossl.) Is this considered a difficult object to find? Any tips.

Are you familiar with the star dangling just "below" the end of the Big Dipper's handle? The end of the handle is marked by Alkaid, and the star below it is 24 Canes Venatici. Keeping those two stars in mind, try and get your bearings using the image at the bottom of this page:

Light pollution, of course, will hinder M51's visibility. However, the galaxy's "core" should remain discernible (though likely dim and indistinct, if sky glow is significant). Start with a lower magnification and get familiar with the brighter field stars shown in the photo -- recognize the area where M51 *should* be -- and you should be able to find it.

Best wishes and luck.

More power, Scotty. You were at 25x or so with the 26mm.

I saw M51 at 40x on a 120mm scope 2 nights ago under light polluted skies (about 4th mag) with thin clouds moving in. It was recognizable, but still only took about 1/8 the field width, maybe a little more.
