    What I think you should do is decide exactly what you do want to do. Is it visual observing, AP of planets, short exposure (30 seconds and less) of DSOs, or long exposure DSO imaging?

    If you say all of them, well no scope does that as they are all very different. You can get a mount that will handle all of these things, a VERY robust EQ mount and it will cost you about 4 times your budget, just the mount.

    You can get an 8" SCT on a goto alt/az mount which will be a good visual scope, a good planetary imaging scope, and capable of VERY short exposure very limited DSO imaging with a focal reducer for about double your budget.

    You can stick with the scope you have (or with the 102 refractor that comes on that mount which I would rather have than the 130mm reflector) and deal with the vibration issues (which are also less with the refractor on the mount) and be capable of decent visual work (obviously much better at a dark site, everything is) and the short exposure DSO work with a light CMOS camera like a ZWO imager.

    You can get a CG4 manual equatorial mount, a tracking motor, and a refractor for decent visual work, short exposure and longer exposure (into the 2-3 minute range) for close to your budget. There is no goto, so you have to find the target manually and there is no possibility of auto-guiding to increase the exposure time, but a LOT can be done with two minute exposures. You also have the option of using the mount with an 8" SCT for good planetary imaging and more light grasp for better visual work. This option (as any quality EQ mount offers) gives you more flexibility.

    Or you can forget about the imaging all together and concentrate on the best visual only scope you can afford, I would probably go this way myself and leave the imaging for later, you still need a visual scope while the imaging rig is at work (gets pretty boring just sitting there watching it collect photons). I would get an 8" manual Dob, a comfortable variable height observing chair, and a few quality eyepieces with my funds and start saving for a good goto EQ mount (an AVX at the VERY least) while I'm using that Dob and learning the skies.

    Even with the appropriate equipment, astrophotography will not be very satisfying in your home area unless you travel to darker skies. Even the biggest scopes and best cameras can only do so much when the viewing conditions aren't good. If you're craving deep sky images, I'd recommend perusing observatory grade photos. If you're looking to learn the basics and poke around the solar system and brighter DSOs, I'd focus your funds toward what you've learned in this thread so far. Beef up your existing equipment as well as you can afford, learn the sky, and familiarize yourself with the nuances and limits of your OTA. That'll help you get a better idea of what you hope to accomplish in the long run. I've only been doing this seriously for a couple years myself, but I would say unless you have a large amount of disposable income, put the AP on hold for the moment and master the art of viewing.

    so, I think I want to be able to do somewhat decent planetary imaging and be capable of very short exposure for limited DSO imaging.

    The night before last, I had a terrible experience (the batteries were dying), but then last night after I changed the batteries I had the best experience yet! I was in my backyard for 4 hours. Just for fun, I was able to find some tips on how to get pictures with your iPhone, and I attached an iPhone adapter, plugged in some headphones to snap to reduce the shakiness, and was totally able to capture Andromeda.

    Now I know this is totally weak Childs play to what you guys can do, but I think I can get even better quality if I can get the camera settings down right, get it to track for stacking photos, and play with processing. I have seen some pretty cool, decent quality iPhone photos of DSO's after processing on the youtube channel that showed me how to do this (If anyone's interested, https://youtu.be/9xqqt6LcQ3g).

    I want to be able to do this! But with better quality. As much quality as I can without going too far out of my budget. (I think I can go up to $800 xD)

    I think I can handle no go-to, as long as I can find stuff on my own. But what would the tracking motor be for on the "CG4 Manual equatorial mount, a tracking motor, and a refractor, short exposure and longer exposure for close to your budget"? I thought that was to track stars, which allows you to get more exposure?

    Sounds like you may be down to two options at the top of the list.

    The decent planetary imaging and capable of very short exposure for limited DSO imaging is the 8" SCT on a goto alt/az mount with a focal reducer.
    https://www.highpointscientific.com/...elescope-11069
    https://www.highpointscientific.com/...orrector-94175
    https://www.highpointscientific.com/...or-cmos-camera
    This comes in around $1465.

    The decent short and longer exposure DSO imaging along with sharp visual optics at close to your budget is the Omni refractor with the tracking motor.
    https://www.highpointscientific.com/...elescope-21090
    The tracking motor is at Orion's website telescope.com item # 07829 and cost $100 or you can get a dual axis drive for $170 (I use the single).
    You can use a DSLR or a CMOS imager ( a used DSLR body can be bought very cheaply on ebay)
