    Default AP: which scope should i buy ?



    Hello everyone!
    Due to a massive delay in shipping my Celestron C8, i decided to cancel the order and rethink which gear should i buy in order to do astrophotography.

    After some research i came out with the opinion that an APO Refractor Telescopes is the best option due to the major aperture, the quality of the lents and so on.
    Are the following articles suitable for my needs ?

    - Scope: Skywatcher Esprit-80ED Professional - 80mm f/5 Super APO Triplet Refractor https://www.teleskop-express.de/shop...Super-Apo.html
    - Autoguide scope: Orion AC 80/400 ShortTube Orion Telescope AC 80/400 ShortTube A OTA
    - Mount: Skywatcher HEQ-5 Pro SynScan GoTo Skywatcher Mount HEQ-5 Pro SynScan GoTo

    Other few questions...
    - What is the difference between an 80mm and 100mm in terms of field of view ? Is the price justified ?
    - Can i fix the orion on the skywatcher or do i need a specific bracket ? Also, which camera should i buy ?
    - Because i'm going to use an APS-C reflex, do i need a flat field correction ?

    Thanks in advice

    Hello. I'm not the person to give advice on the subject since I'm new to AP myself, but the scopes I've been looking at are 80mm scopes mainly for the wide FOV. The scope I'm eyeing right now is either an Astro-Tech at80edt or Explore Scientific es80ed. Both are getting high recommendations and are under $800.
    Current gear: Meade Polaris 130 Newt scope with manual EQM and a Canon Rebel T5 (1200D) unmodded dslr. This moon photo was my first AP photo that has turned out ok so far.

    Many people use the Skywatcher 80mm Esprit as it was designed for AP in mind. You should get some good results with it

    Jessead82, neither of these scopes (though good) are available in Europe though there is probably an equivalent ES scope available through Bresser.
    Refractors: Antares 105 f/15, Bresser 102 f/13.2, Celestron 102 f/6.5, 150 f/8, Stellarvue 80 f/6.9, TS 102 f/11, Vixen 115 f/7.7
    Mounts: Manfrotto 055PRO, Celestron SLT, Celestron CG-5/ Argo Navis, Vixen SXP Binoculars: Celestron Eyepieces: A-Z

    The weakest link in the optical chain is the large nut located directly behind the eyepiece/ camera. - Gabrielle

    I just received my 100 but before that I was using an 80 ES APO. The 80mm doesn't have much to do with the field of view as the focal length. The 80 Esprit has 400mm vs the 100 which has 550. Consider it like a zoom lens the closer you can zoom in the more detail you can get but for large objects like M31 the 100 may not frame well depending on your camera so you would loose some of the target or have to mosaic. There are field of view calculators for CCD camera that allow you to punch in the info to get an idea, Google will help you find one that works best for you.
    I would go with an off axis guider if you can they make life pretty easy vs an additional guide scope and weight. For the scope you mentioned a 60 or 50mm guide scope would be fine too.
    Skywatcher Pro 120ED, Explore Scientific 80 CF APO, Orion ShortTube 80, Meade ETX90, Celestron GT 120mm, Celestron C8, Astromania 60mm Guidescope, Celestron AVX Mount, Orion Atlas Mount, Explore Scientific Twilight 1, QSI 683 WSG, Astrodon Filters(LRGB and 3nm), Canon T3i & XSi(XSi is a full mod), ZWO ASI 120MC & ZWO ASI 120MM-S (with LRGB Filters) as well as for the daytime a Lunt 35mm Ha Solar Telescope, Lunt 1.25 Hershel Wedge, and White Light Filters

    I currently use the william optics 102mm apo. With a full frame sensor, like a Dslr you can just about fit all of andromeda in the frame, I use the atik 414 which is a much smaller sensor sensor therefore a much smaller field of view. Its a great scope for nearly all type of deep sky imaging, apart from imaging the entirety of large nebula such a the heart nebula or North American nebula. I would highly recommend this scope and even the 80mm apo from william optics (or any similar seller). Its easier for starters and youll get a wider field of view. It comes down to personal preference.
