Hello,
I have the beginner Meade telescope (D=90mm F=800mm f/8.8), an old one. Below are the pictures taken with this telescope and my Nikon D3100. I would like to purchase a (intermediate) telescope that gives clear details of Jupiter, Saturn, and nearby deep-space objects. Please advise. Thanks so much in advance!

With this set of photos I'd question whether you really NEED a bigger one! I also question whether an intermediate 'scope would really give that much improvement on what you already have. I have a 127mm Maksutov, which I normally recommend but I don't think my images are better than yours, maybe marginally but that's all.

To get anything much better, you'll need to be thinking of a 5 or 6 in APO refractor (v. expensive), a 200mm Maksutov (expensive) or 12" Newtonian.

Many of the brighter DSOs are already within range of your telescope.

If you are wanting to take pictures with it, they do get expensive. For visual observations, with more difficulty with picture taking (even though it can be done) would be a Lightbridge. Several of the veteran people in my astronomy club use the 12 inch for deep sky visual work. Personally, I think the ten inch would be a good one to have.

If you want to get really serious about astrophotography, it really depends on how much money you want to spend. Most of the people that I know that do significant photography will use an SCT around 8 to 10 inches, depending on how portable they want it to be.

As Phillip said, an Mak Cass can be very good for photography as well as a good refractor. Both of those can also be good for planetary work.

Weight can also be a big factor, the larger the telescope the more effort and time goes into setting it up and storing it after use.

The question you ask really opens a wide door and is normally one of the more difficult ones to answer.

Tell us more about what you want to do and we can direct you a little better.
