Which telescope to buy?

Below are some of the telescopes I've used in recent years, ranging from ~30 -3000 dollars. (shortened for YTs character limits) What would I get if I was buying now? -Ive included amazon affiliates links to telescope I've owned and would recommend below (for different niches!) https://amzn.to/2IkWRZl Im currently in a city (bad sky pollution) which means I can only really do planetary observations. The 5in maksutov is perfect for this. Long focal length gives good magnification on planets. The German equatorial mount is MUCH easier to set up than alt-az mounts that require star alignment. The GE you can just put down and more or less be ready to go. The telescope is compact, and easily transportable. https://amzn.to/2Kh3bUt If I had decent skies, I would start with a dobsonian. Cheap, lots of light gathering, lots of resolution. Bulky telescopes- no tracking, but v. easy to set up and start with. 6in is the minimum size I would go for. Easily portable, capable scope. https://amzn.to/2UrHWnF 8in is getting a bit bulky, but almost twice the light gathering of the 6in. https://amzn.to/2KjXXXS 10in and 12in are getting right to the limit of what one guy can handle, but at the end of the day, more mirror means you can see fainter thing! https://amzn.to/2D3scwd If you want to try your hand at astrophotography, the scts are the way to go. 8in is easily handleable and probably the best compromise between size and portability. https://amzn.to/2Kns6FU the 11in version Ive got is a BEAST! https://amzn.to/2G5mOJY Price $35 76mm reflector dobsonian mounted (Celestron Firstscope) Weight ~ 1kg (a couple of pounds) Setup time ~0 East of Transport 1 Short focal length- wide angle field of view. Finder not really necessary. Ultra cheap, good views of Moon, Jupiter Venus, rings of Saturn, bright, wide separation double stars, and brighter deep sky objects such as M13. I was not particularly impressed with the optics on mine, but for 35 bucks, you cant complain too much! Price $200 90mm Maksutov-Cassegrain, dobsonian mount (Orion Apex) Weight ~ 1kg (a couple of pounds) Setup time ~0 East of Transport 1 Longer focal length means smaller field of view for comparable eye pieces. I was impressed with this scope on the planets. It vastly outperforms the Firstscope on optics. The scope comes off the dobsonian mount on a quick release and can be mounted as a spotter scope (the main reason I got it). The dobsonian mount here (one arm) is exactly the same as the mount for the Firstscope. These are sort of the poor mans refractor. Great views of Moon and all the bright planets. Picked out Titan (brightest moon of saturn) with ease. I got this telescope for two reasons, firstly for outreach, in that you can just grab it and point it in seconds, zero setup time. Secondly I can mount it piggyback on the CPC11 (see below) and use it as a spotting/ guide scope. The Maksutov has the 'nice' feature that its a closed tube(helps keep dust out). The Mak. will have the edge on planets/ guidescope etc due to its longer focal length, but the Newtonian will be more all around bang for the buck. Price $600 10in Newtonian reflector, dobsonian mount (Celestron Starhopper) Weight ~ 15kg (~30lbs) Setup time ~10 mins to carry parts outside, 10 mins + cool down. East of Transport: Telescope is about the size of a small child (although not that heavy). It is big and awkward. Difficult to handle for the small. Almost the biggest telescope you can fit in a compact car (the reason I got it). The long open optical train requires periodic alignment (columniation) if it is frequently transported. Powerful deep-sky scope. Near zero photographic potential, but fantastic views of nebula, globular clusters and galaxies. Great scope for planets too. At this size the moon is getting too bright to look at for any length of time. Like most big newtonians, short focal ratio, which pragmatically means you get quite wide angle views. Again well suited to deep sky observing. Price $1500 90mm (3.5in) Stellarvue apochromat, -no mount, tube only (Apo Triplet) Weight ~ 4kg (~8lbs) East of Transport: The telescope is small and easy to transport. Comes with a bag that will go on an airplane as hand baggage. Worth the price for the aperture? Probably not unless you are in a fairly specific niche. This makes a great wide angle lenses for guided photography. As a guidescope its focal length is kind of short. That basically means the field of view for a given eye piece is wide. You need a very short focal length eye piece to get good magnification. I found myself using a 4mm eyepiece to look at planets, and even at that the image was small.
