Stellarium will only point your telescope to where it thinks the object is. There are other pieces of software you need to take longer images. Please read the sticky right above this post to give you an idea of what is involved.

You can try.

The limitation for 30 seconds would be from the lack of good tracking. Those would include polar alignment and the ability of the mount to track. Using an autoguider would be the next step to help with longer exposures.

Go through the post that JayTee linked to, it gives you a really good reference for the software you need. Based on your equipment you have in your tag we have a lot of the same equipment other than the mount. The EQM-35 mount is what you would want to use for long exposure. At a minimum, you will need to add a guide scope and guide camera. Weight also comes into play and your mount can only handle 22 pounds. For AP you want to try and keep your weight down to about 50% of your mount's rated capacity, so that means you want to try and keep the total weight to around 11 pounds. That number isn't hard and fast but the lighter the better. The lighter the load, the easier it is for your mount to track accurately. We have the same OTA and camera, the EvoStar 80ED and the T3i. The OTA is 7.3 pounds and the camera weighs 1.5 pounds, for a total of 8.8 pounds. You will need to add a guide scope and guide camera. I use a ZWO 120mm for a guide camera and the Orion 60mm guide scope. My guide scope is 2 pounds, however that does not include the weight of its dovetail or tube rings, and the camera is a couple of ounces. Now I've exceeded the 50% of your mount. So, you need to look for something extremely light for a guide scope.

Hope this helps in your journey to take long exposure AP. The folks here are a wonderful sort and are willing to answer your questions. I was a newbie myself not too long ago and without their help, I wouldn't be where I'm at now in my own journey in the hobby.
