finding M33

Recommended Posts

I intend to image M33 soon and was wondering if it will be visible in my finder scope or will I need a low power eyepiece in the OTA?

I would like to know this too, spent about half an hour looking for it last night in my finderscope with no luck, which is odd as wiki says its naked eye visible?????

I could find Andromeda a little above it with no problems.

Totally depends on your skies, but I suspect not. It has low surface brightness and is washed out by light pollution. M31 is much easier and can be seen under most conditions.

Under dark skies it appeared as a faint round glow in 15x50 binoculars to me, and not dissimilar in a 4" Widefield scope.

Oddly enough this was my last target of the night, it certainly wasn't visible in a 15" exposure so I ran the sub through astrotortilla and it barely moved the scope when it re-centred. A 5 min sub showed it nicely.

I did m31 last night but still have to process, think I'm going to stick with naked eye objects for this winter season as its my first winter with a astro photography, m42,m31,m45 etc should give me hours of fun.

Thanks all.

Get the GoTo to align itself using a 3 star align. Slew to the star Metallah ( alpha Triangulum ) and then use the Center Object routine to get the star bang on ( do not just use the direction arrows on their own use the routine ) now the mount will easily find M33 from Metallah and it will be in the middle of the sensor. M33 is very dim to find with a finder but is a Binocular object.

M33 can be seen in a 50mm finderscope or binos if your skies are better than mag 5 or so. It's an easier spot once you've found it before.

It takes a bad night here at my back garden not to be able to find it.

Never seen it naked eye though. That would be a tough call!

In my skies, m33 showed up in a 4 min exposure, but was not visible through my 9x50 Finder. My skies are middle of the road, not terrible, not brilliant.
