I have actually done a fair amount of imaging with a 60mm Tasco and similar refractors. The key is to keep is light and keep it simple. You definitely want to go with Method Cb. If using a DSLR you will need a DSLR to t-thread adapter which can then screw onto the t-thread on the telescope. The best celestial target is it moon. If your camera supports mirror lock-up use it. Also, plan on using a remote switch to trip the shutter. The overall Plan is to raise the mirror, count to 3 to let the vibrations settle, then trip the shutter. Plan on taking lots of pictures. My routine is to set the focus using a Bahtinov mask on a bright star, move over to the moon, position is a bit off-center so that it will drift to the center when I take a picture, and repeat 8-16 times to get enough images to stack.
Plan-B is to use a lightweight astro camera like a small ZWO (I use an uncooled ZWO ASI294MC) and SharpCap on a notebook computer.
Plan-C, get a lightweight eyepiece mount for a cell phone and go that route. These can actually work fairly well.
Food for thought.
The most important thing is to relax, take your time, and have a fun learning experience.
