Since this scope has a 2": Crayford focuser, this should be the adapter that will work.
Prime Focus Camera Adapter for 2" Crayford Focuser | Orion Telescopes
Check your focusing tube, it should have threads inside the tube, once you take off the existing eyepiece adapter. Both the 1.25" and 2" adapters screw on and off, and as far as eyepieces go, the 2" is nicer, but usually a little more expensive. Once you get to eyepieces below 10mm the image starts to degrade a lot, due to the higher magnification.
A 2x Barlow lens is a nice addition, coupled with the 25mm eyepiece it will get a very nice view with a good range of magnification and still keep good image quality. Couple it with a 10mm eyepiece and it works, but it's not easy to get good sharp focus. Anything you look at will also move out of the view pretty fast. I've used mine for the moon lots of times, you get about 30 seconds if the scope is stationary without tracking. You can also get a 3x Barlow, but image quality degrades more than I like, a friend has one, we normally use the 2x. It's great for moon and planets, and sometimes for nebulas, for deep space stuff I usually stick to the 25mm eyepiece by itself.
For astrophotography you'll also need a tripod mount for it that has tracking capability. Otherwise the moon is about all you can successfully photograph.With a stationary scope, or camera, I've always gotten start trails with anything over about a 4 second exposure, you'll need at least 30 seconds for deep space objects like nebulas, or even planets like Jupiter or Saturn. I Haven't tried it with my scope, no tracking, but with the K30 on a tripod just a might sky shot gets star trails at 6 or 8 seconds. My scope is a Orion 6" Sky Quest Dobson mount, and just got a Meade Starfinder 12.5 inch, also Dobson mount but a beginner model. Haven't had a chance to take it out yet, only had it a few days, but got the primary lens cleaned and part of the collimation done.
Your 80mm objective is about 3.25", and a refractor type scope generally gets a very good image, so it should probably match a 5" reflector scope as far as image quality goes (looking through the eyepiece). I've used a 5" refractor at a star party a few years ago, it made my 6" look like a toy. It was every bit as good as a friend's 8" Orion identical to mine. Knowing what a refractor can do, I think you'll be pleased with it, and Orion always uses very good optics. Their eyelenses are good Plossl lenses that should work well too, and if it were me, I'd shell out a few extra bucks for the 2" lenses.
One note, I'm sure you may have already heard this, but it's very important and I have to repeat it. DO NOT point that thing at the sun. If you want to do solar viewing get a solar filter, or use it to project a solar image onto a sheet of typing paper. That works well, I've done it with my Orion. You can use the shadow to align it so it's pointed in the right direction, it's tedious to get it exactly right, then hold a sheet of paper about a foot from the eyelens and it will give you a good image of the sun without blinding you. Never ever look through either the scope or the spotter scope at the sun. It WILL blind you in about 2 seconds. I put my sheet of paper on a clip board, once it was focused I could count sunspots. The further away you hols the paper, the larger the projected image will be. About a foot away or a little more makes the sun's image about 6" diameter.
I'm not crazy about the Starry Nights software that comes with the Orion, I downloaded the K Stars software originally written for Linux, and ported over to Windows a while back. If you can find it, there's also a Linux Live CD named Cloudy Skies that is a bootable Linux CD that is all astronomical software and has several planetarium programs. I think they dropped development a few years ago, my copy is about 10 years old.
See if you can find a red filter for a flashlight, it's great to light up the area for lens changes and such, and won't kill your might vision. An eye patch to cover the eye you are not using is also helpful, your eye will get tired if you try closing one eye and looking with the other. Green astronomcal laser pointers are also nice if you're trying to show someone where you're looking, never point one at an airplane. Red ones don't work for astronomy, you can't see the beam at night. (I've tried)
All of this is assuming you're new to astronomy, if you already knew most of it, I'm not trying to treat you like an idiot. I've been intoi it for around 15 years since I got my first cheap, small Meade beginner scope, then got the Orion 6" a few months later. I love the Dobson mount, it's more stable than most tripods. I was able to see both Saturn and Mars at closest approach years ago, a couple of lunar eclipses, and have spotted a number of deep space objects... Orion Nebula, Ring and Dumbbell Nebulas, Double Cluster, Andromeda Galaxy, Hercules Cluster, Crab Nebula once, and several of the others around Lyra and Sagittarius. The coldest winter nights will always get the clearest skies. I haven't tried any photography, neither of my scopes has tracking capability. I have a T mount to Pentax K that I use for a Lentar 135mm T mount lens, but no scope adapter.
