Galaxies and Nebula viewing
Hello all,
As a newbie and after being helped with alignment I have that kinda figured (when I usegoto , whatever I’m looking for is usually in the eyepiece when it gets there) I’ve been looking at Jupiter mars Saturn, Sirius, Polaris and a few others. My question is this, when I select a galaxy or nebula what should I see? I never really see anything and I don’t know what I’m looking for to adjust to on the chance I’m off a bit, I’m using the Celestron 8SE I know I won’t see great detail but shouldn’t I see something? I live in NE Florida and out in the country and it’s relatively ‘dark’ . I’m using the lenses that came with it as I’m not sure what to buy in that area yet. Any advice or help is appreciated

Re: Galaxies and Nebula viewing
Galaxies and nebulae called faint fuzzies for a good reason. Majority of them are faint and observing them is acquired skill.
I suggest to start with a few which are large, bright and obvious. Once you see a few you will get idea what to look for.
Try to find Orion Nebula (M42) and Andromeda Galaxy (M31).

Re: Galaxies and Nebula viewing
This post should help a lot. It's the best simulator I've used that gives you a fairly good idea of how little you're going to see.

Re: Galaxies and Nebula viewing
Thanks to you both, the simulator helps a lot, I’ll play around with what I got and then decide on a different eyepiece after I get better at it

Re: Galaxies and Nebula viewing
A hint is to use a lower powered eyepiece to increase the size of the field of view. Lower powered eyepieces have bigger numbers, e.g. 25mm, 30mm, etc. This will make it easier to find your target.

Re: Galaxies and Nebula viewing
As Andrey mentioned galaxies and nebulae can be quite challenging to observe for beginners. Part of that is not having a frame of reference for what you should see in the eyepiece. That comes with experience. Another key factor is how bright your skies our from light pollution and how much extraneous ground lighting impacts your viewing location. Both those issues impact your ability to dark adapt and rob you of contrast when looking through the eyepiece. In terms of galaxies, I can point you to my article here on the site "Why Can't I See That Galaxy? for some ideas of what we deal with when trying to observe them. You can find it here:
app.php/article/why-can%CA%B9t-i-see-that-galaxy%CA%94
The darker your location the better your chances. As Andrey mentioned try for the brighter ones, such asMessier 42 in Orion and Messier 31 in Andromeda. Once you have a few under your belt, you gain a better sense of what you are dealing with in terms of expectations. Good luck and never hesitate to ask questions. We all started at the beginning, and we each progress at our own pace. I am fond of saying "the more we learn the more fun we have, and the more fund we have, the more we learn." I hope you find that is the case for you as well.

Re: Galaxies and Nebula viewing
In my location with my current scopes, all but about 5-6 of the brightest galaxies are blotted out by light pollution. YMMV.
Did anybody mention using averted vision? Instead of looking straight at a dim object, look just a bit off to the side. Here's one article on it:
https://en.wikipedia.org/wiki/Averted_vision
Another trick if you're unsure if you have your target in your field is to tap the side of your scope to cause a little vibration. That can help dim objects stand out from the background - your eye will (might) pick up the movement of the target. It seems our eyes are rather sensitive to movement in low light environments.
