    Default Looking to get a decent telescoping lens for astrography with spending 11,000 dollars



    https://www.amazon.com/High-Power-10...ct_top?ie=UTF8 I've been looking at this one seems to be okay. I plan on taking pictures of the Orion Nebula, Andromeda etc. And other large easy to find objects. I would like to spend maybe 250 dollars max. What is the best option for this? And would this work on higher magnification with out tracking. I am assuming you may have to kick down the exposure time. To reduce trailing. FYI I meant to put without spending 11,000 dollars.

    Elle, you had me going there for a minute... Was dying to see what you'd buy with 11 grand (hopefully something for me too...... just kidding!)

    I wish I could give you some advice, but I'm just a lowly DSLR user. I'm sure others in the know will chime in.

    Have a great night,

    Wouldn't work without tracking, and slow photographic speed, most of us shoot no slower than f6 on small refractors, efl of 400-500mm, and Orion neb still requires 1 hour plus to be reasonable.

    At a guess, at that price the glass is not going to give you fringe free images. Chromatic aberration can be moderated somewhat by software so it may prove to be a great addition to your kit.

    As a 500mm f8, it'd be 1000mm f16 with the 2x converter - which you could probably live with for moon photos. But for DSOs, f16 needs 4x the exposure you do at f8.
    So you're going to need a tracking mount - without one you're going to see trailing after around a bit under a second at 500mm, and half that at 1000mm.

    I have 220mm cannon telescopic glass. I am going to give a shot tonight. In heavy LP. I made some decent shots out in Joshua Tree. Wish I would of kicked up the magnification.

    If astrophotography were as simple as buying a $100 lens for a DSLR we would all be doing it. A lens with a focal length of 500mm and an focal ratio of f/8 will have an aperture of 62.5mm ( ~2.5 inches). Like TerrytheC said, it is very slow and you will need a tracking mount.

    If you want to do some astrophotography with your DSLR and a camera lens think about using a ~f/1.8 to f/2.8 lens and making nightscapes or star circles. If you are using a Canon DSLR, you can get a old Canon film SLR lens and an adapter for less than $100 that will do very well. Since you don't have a tracking mount, set up on a tripod with your highest ISO setting and do very short exposures (1 to 3 or 4 seconds).

    If you are interested in imaging deep space objects then probably the least expensive way is to get an Orion ST80A 80mm aperture f/5 short tube telescope (~$200) and use it as a camera lens on a sturdy tripod. Without a tracking mount you will be limited to 1 to 2 second exposures. Take a couple of hundred of them and then stack with the free program Deep Sky Stacker. This will work for the brighter deep space objects such as M45, M42, etc. See: Minimalist Astrophotography

    Starting low budget, I recommend a progressive approach: it is not convenient to spend money to have a setup difficult to manage and that gives you frustration

    1. fixed tripod and short exposures, you'll need an intervalometer and you can get results like this:
    Orion Wide Field from Fixed Tripod (pterodattilo) - AstroBin
    wide field astrophotography is really beautiful!!

    2. then if you are passionate you can spend a little more buying a tracker (300 to 700$ approx) which will give you access to 100-250mm focal length exposures and allow you to take minutes long exposures with shorter focal length:
    Elephant Trunk on a 135mm (pterodattilo) - AstroBin
    Veil Nebula 135 mm (pterodattilo) - AstroBin
    Rosette Nebula from my balcony with a poor zoom (pterodattilo) - AstroBin

    there is a bunch of objects that fits in 100-200mm focal length and even less!! Still, having a 8" newton, I plan to make composition of sky objects with a wide field because they are spectacular (auriga, pleiades + california, barnard loop ....)

    3. Finally, if you want to spend more and access longer focal length, then you'll need a proper equipment: mount, autoguiding and a real telescope. Here you can spend from 1500-2000 for a basic setup, up to ... whatever you want, but the important is that you have experience not to throw money away (you will in any case but the more you know the less you will)

    FYI: I decided not to go with telephoto above 200-300mm because they gave me some delusions: as soon as you mod the camera, even the good one will perform poorly due to chromatic aberration and, unless you want to spend $$$ on high end telephoto, you will opt for telescopes.

    Per an old Canon site:
    The flange to sensor distance on EOS cameras is greater than it was in FD cameras. This means that it is not possible to position an FD lens correctly for infinity focus on an EOS camera. This is why corrective optics are needed, but the optics in adapters are generally not high quality and will degrade the image. This is why using FD lenses on EOS cameras is not generally recommended.
    The Canon FD-to-EOS Adapter uses the equivalent of a Single Lens 1.4x TeleExtender to address the Flange Distance Issue. This introduces both additional Focal Length and numerous Aberrations.

    It is better advised to pursue old Olympus OM or Film-Age Nikon or Pentax Lenses - all of which can be found Rather Inexpensively. Each of these Lens Families uses a non-Optical Adapter for EOS.
