There was a tread from last week that asked about using a simple alt-azimuth mount to do imaging of galaxies. There were comments suggesting yea or nay and a discussion about the limits imposed by field rotation. A further complication was added when the OP reported that the mount in question had no motorized tracking or guiding.
So, the question then became is it possible to get an acceptable image of a galaxy using a fixed, alt-azm tripod? One can certain find wide-field images that include the Andromeda Galaxy (M31) or the Magellanic Clouds that were taken with a single, short exposure with a fast camera lens but those generally don't reveal much detail (at least not in a way that might be termed an "acceptable" astro photograph, pretty yes, but maybe not that recognizable as a galaxy).
To be inclusive it should be noted that before computer-guided mounts and digital cameras it was fairly commonplace to manually guide equatorial mounts when imaging with film-based cameras and a lot of really fine images were produced that way. In fact, many years ago I strapped a 35mm film camera with a 50mm f/1.4 lens to the side of an alt-azimuth-mounted, department-store refractor that was used to manually track a star for several minutes to create an image of the center of the Milky Way (no slow-motion controls, just my hands on the body of the optical tube). So, yes, manually guided images are nothing new.
In any case, I eventually posted an image of M31 to the original topic that I took using a 105mm camera lens from a fixed tripod using a series of 0.5 second exposures with a cooled ZWO ASI178MM camera. At that time I stated that with some DSO targets it would be possible to get an acceptable image but that it might not be that practical to do so (most of us probably don't have the patience to sit by the telescope for hours at a time to manually track a target, particularly when restricted to a non-motorized alt-azm mount).
My original image was done rather quickly under red/orange zone light pollution with a total integration time of 12 minutes and several days later I set out to see if something better could be done. Well, I had a relatively nice evening this past Monday and I sat outside for about one hour and captured just over 5000 subs using that same 105mm lens and ASI178MM camera that was mounted on a manually positioned Vixen Porta II alt-azm mount (no motors or auto guiding, I just let the field drift for one minute and then repositioned the framing).
Herein is the result from combining those 5000+ subs that were each exposed for one half second (luminance only with a Baader Fringe Killer filter). The total integration time was 42m 50s (5140 x 0.5s, lowest read noise gain setting in SharpCap). Image processing was done in PixInsight and Photoshop CC2017 and I was still working under red/orange zone light pollution. The Nikon 105mm AI-S lens was stopped down to about f/3 using a front-mounted, step-down filter ring and I focused as best as I could using a 52mm diameter Bahtinov mask. When I say "best as I could" I need to add that this Nikon lens has a fair amount of chromatic aberration which is plainly detectable given the 2.4um pixel size of the Sony IMX178 sensor. This same lens seems to do fairly well with narrow band, not so much for one-shot-color or luminance.
I think this image is okay, but I really wonder how good you could get under dark skies with a better lens and when working with a camera like the color QHY5III-178C. Perhaps someone already has such an image that they would like to share (requirements, fixed, non-motorized alt-azm mount and reasonable image scale).
Lastly, there are three galaxies in this shot, the Great Andromeda Galaxy (M31), M32, and M101 (lower right). Given those two smaller galaxies I'm fairly sure that other galaxies could be imaged with similar techniques (if you have the time or patience to do so).
