    Default High End Reftactors



    Hi there, I see many recommendations for refractors, and telescopes in general, for a lower tier price range but very little is available in the higher price bracket.
    I may be in the market for an approx $20,000 USD +- 5k in the next year or so. Mounts aside (another topic entirely), and for astrophotography exclusively, there are some options but I don't know which I should pursue.
    Of note, there are TEC 160 or even 180mm, tak FSQ 130, on the lower end a televue 127, Sky Rover sextuplets, astro-physics 130-160 range triplets. I'm sure there are lots of others. Does anyone have any experience with high end scopes of this kind? I had my eye at first on a takahashi TOA 150 but I'm told this is primarily an observing scope and the FSQ130 would be better for my purposes.
    At present I have a skywatcher esprit 100. It's an f5.5. I will be photographing nebulae, and I would like a bit of extra reach so that some of the smaller galaxies are slightly bigger in my image (I understand this won't compare to a CDK/RC/SCT etc). I'm open to focal ratios between f4 to f10. I eventually want to use a 16803 chip with it for wide field.

    Thanks in advance!

    Hi Francisco, and welcome to the Forum. I suggest you post your query in the AP forum: Astro Imaging Forum
    As you are in Australia, you might want to also ask in the IceInSpace forums, eg: Astrophotography and Imaging Equipment and Discussions - IceInSpace

    Good luck and all the best,

    Dean

    I know next to nothing about HI-END anything. However, I have noticed when shopping for AP equipment that all the HI-END stuff tends to be listed on a site called www.astromart.com

    But you have to pay, and pay dearly, just to join the website and the priviledge of seeing the prices are being charged. And it is mostly an American thing from what I could tell. Still, you may want to check it out.

    Hi Francisco, welcome to the forum. I am sure there are more experienced observers than me on this forum, but I thought I would answer.
    It depends where you are imaging from; can you give an idea of your sky brightness where you are going to be imaging? Atmosphere conditions will also be important - high altitude and dryness will enable better images. With the atmosphere and water vapour, and vibrations from the ground, there will be severe limitations on the effectiveness of your equipment. The maximum resolution of your scopes depends on these conditions. The mount will cost more I think. The scopes only go up to around 5000-10000 USD (not 100% sure). However, you may need a permanent observatory with such a big setup....
