By themselves smaller scopes are great from brighter objects like M42 Orion Nebula, lunar, globular star clusters and planetary objects etc.
Key to good images for low light stuff is to use a camera. It's sees far more than our eyes are capable of seeing. Not sure about your scope, but if you can adapt a digital camera to the scope, it opens up a whole new universe.
Another issue it seems you do not have an equatorial computerized mounted scope or go-to scope. They mount allows it to pinpoint, locate and track an the object across the sky as the earth moves under it using a key pad. They've come down in price considerably for the lower price scopes. I bought used stuff and designed my own mount using scrap from a salvage yard and built a small observatory around it.
Andromeda M31 is tough to image even with a higher end scopes. I have to take over 250+ separate images between 30 seconds and 2 minute exposures for low light objects. I then take the digital images into image processing programs and basically combine or stack all the images into one finished image. Hopefully it all comes together.☺
Also Andromeda is a wide field object, so I can use the camera with a 300mm lens and attached it to the top of the scope. Pigging backing while using the scopes tracking mount to find and track images by punching in coordinates/name of object on a keypad.
This brings out incredible details which would never been seen with our eyes though the eyepiece. In fact, anymore I very seldom ever look through an eyepiece and generally watch what the camera sees through the scope, on a computer monitor. My interest here are digital imaging.
Bottom line if your happy with brighter objects like I mentioned, stay with the smaller scope. Just do not expect to see M31 as it appears in #10, using the scope without a camera and proper mount.
My advise, unless you have a lot of interest in Astronomy/imaging, don't waste your money upgrading and just enjoy the night sky with your scope. Even a good pair of binoculars are fantastic in a dark sky venue, like the mountains, deserts or out in the country.
Btw, here's an image of my current scope, you can see the attached camera. All of which is sitting on it's junk yard custom mount and steel pier.☺ The pier goes down through the floor, and is sunk into about 1100 pounds of concrete for stability. Sorry about the long post..
