Decent astrophotographing solution?

I'm still researching about astrophotography and recently joined an astronomy club. My hopes are that in about a year from now I will be able to buy a decent telescope and EQ-G mount. I'm still in a research phase of the astrophotography field but I'm not new to astronomy or using a DSLR. So far I've managed to determine what I want to achieve and that is, good astro photos and decent deep space observations, also I don't like the diffraction spikes that newts do. Here are a few telescopes that caught my attention:
1. Sky-Watcher Esprit 80ED APO Triplet
2. Sky-Watcher 7.5" f/5.3 Maksutov-Newtonian Telescope
3. Sky-Watcher 8" f/3.9 Quattro Imaging Newtonian Telescope
4. Orion 8" f/3.9 Newtonian Astrograph Reflector Telescope
5. Explore Scientific Maksutov-Newtonian F/4.9 152 mm

I'm looking into either a refractor or a newt reflector telescope. The research I have done so far told me that a refractors or a maksutov-newts are better for astro imaging than a newtonian (mostly because I don't like the diffraction spikes), but since price is an issue I'm willing to do trade-offs in effort to get the best for the money solution. Keep in mind I'm only a novice and I'm still researching. So here is my question, which of these telescope is best for my needs and what mount would I need for that telescope considering the weight of all the extra equipment needed? Also what extra equipment would you get for astrophotograping for telescope you recommend? I own a Nikon D7200.

Added (1). I forgot to mention the Orion ED80T CF Triplet Apochromatic Refractor Telescope.

First, enjoy the next year of Night Skies Network viewing of live video astronomy. You will soon see spending a large fortune on equipment and years learning how to use it properly might not be as urgent as you thought.
While you are correct in that most Newtonian telescopes have a center obstruction with straight bar supports that cause spikes, there are alternatives to that:
Edit out the spikes with software.
Use curved support bars. These avoid spikes and minimize diffraction of any shape. These are not hard to make and install, some are available for purchase. Search Google.
Use a clear window instead of support bars. Some good quality float plate glass, if water white color type, might be good enough. It would have to be chosen for optical flatness and parallelism. I have seen some precision plastic windows.
Use an off-axis reflector telescope. There's no center obstruction at all. There are several designs, one is commercially available. Search Google.
Aperture will get you shorter exposure, and a bit better definition. But you pay for it through massive support stands. The rule is the scope should be like a pyramid, Small components supported by ever larger pieces as you go down toward Earth is best.
But I learned the hard way that doing my own massive GEM and fork mounts of machined metals might not have been wise.
Some advocate a sturdier alt-azimuth mounting that avoids the stresses and unsteadiness of a counterweighted telescope on equatorial axles and a tall tripod. This can be of inexpensive wood construction with included or added computer drive motors. This simulates the sky motion up to a point. To do good astrophotography, a third system can be added fairly easily:
A base that tilts by motor to follow the stars (equatorial platform) under the scope base can be built cheaply or bought at reasonable prices.
A rotating camera mounting in the eyepiece tube is linked to a computer for driving at a compensating rate.
Or much shorter than usual alt-azimuth type exposures of selected parts of the sky can be combined later.
Many accomplish good results with a medium to small refractor (less than 150mm diameter and 0.5 to 1M focal length) on a GEM mounting.
Others with large (more than 200mm diameter) reflectors use many different types of mounts, take shorter exposures for fine pictures.
You should investigate many choices at many budget levels. Do not avoid used items. Good telescopes that have been well cared for have the same performance as new for less cost. Astromart and Cloudy Nights websites are a couple where I have seen many. Oceanside Photo & Telescope has had good ones available.
