    Welcome to the forum!

    There are several reasons why it is not suitable for astrophotography.:
    1. A Dobsonian mount (any alt-az mount, really) limits you to 30 seconds maximum exposure due to field rotation.
    2. It does not have tracking motors, which further limits you to less than 1 second exposure time.
    3. Newtonians are not generally able to focus a DSLR camera.

    thanks for the quick reply!i already own a dslr so i was browsing some telescopes and they are all above my budget.i also took a peek at the thread "Minimalist Astrophotography" and i wanted to ask you if astrophotography requires a tracking mount.i'm a newbie at this but i want to learn more.also is there a budget telescope that's also good for astrophotography?

    You can do planetary AP without a tracking mount, though tracking will considerably improve the convenience. Planetary AP is usually done using video, at fast frame rates. You would be able to shoot a few seconds of video before the scope has to be repositioned.

    You absolutely need tracking for imaging deep space objects, though. A tracking alt-az mount will allow exposures up to 30 seconds. To go beyond 30 seconds, you need a tracking equatorial mount. Deep space objects benefit from exposures that are several minutes long.

    Tracking and backfocus are the biggest obstacles in astrophotography. If your mount can't track an object to within a reasonable degree of accuracy (Which is greatly improved by guiding), your image will become more and more blurry the longer your exposure is. A tracking equatorial mount is the golden standard in astrophotography because it allows for long exposures with no field rotation. Next would be a go-to Alt-Az mount which, unless paired with an expensive field de-rotator, will start to show blurring past about 30 seconds as your target begins to rotate relative to your scope. If astrophotography is your goal, start with a GoTo EQ mount and save yourself a lot of headache down the road.

    The next issue is backfocus. An excellent visual scope will not always be an excellent photographic scope due to how far the focuser can travel. Eyepieces often come to focus at much different points than a camera sensor, so the focuser may or may not actually bring the image into focus for a picture. Some scopes (Astro-Tech/GSO Ritchey-Cretien scopes are a great example) get around this by using extension tubes to effectively increase or decrease the lenghth of the focuser, allowing use with just about any photographic or visual equipment.

    If you want to get into astrophotography, the most hassel-free way to go is to start with something that is known to work than to try to adapt sub par equipment.

    Hi,

    My impression from your postings here on the forum is that you are just starting out in astronomy. Not to worry as we all were once in the same position. The people here on the forum can be a great place to get answers to the questions that you will have. One thing to watch out for is that we like to spend other people's money.

    To answer your question: The Heritage 130P is not designed to allow a DSLR to come to focus. Also, it does not have a tracking capability. Tracking with an Alt-Azimuth mount requires a computerized and motorized system. To do any photography of Deep Space Objects such as nebulae, galaxies, star clusters, etc. requires a tracking mount. Add to this, before you can photograph something, you must be able to find it. Unless you are very experienced and knowledgeable about astronomy, you will not be able to find objects in the sky without the use of a computerized goto telescope mount.

    The advice others have given to buy an excellent German equatorial goto mount with a decent telescope is, if you look at it from a time perspective, is the lowest cost way to go. What they are saying is get a mount that can grow with you as you advance your photography skills. The minimum cost of such a setup here in Greece is 915 Euros (plus ~50 Euros shipping from Germany). Here is what you need to get started:

    • Mount and tripod; SkyWatcher EQ5 SynScan GEM: 665 Euros
    • Telescope: SkyWatcher Explorer 130PDS with 2 inch dual speed Crayford focuser: 205 Euros (you will not need a dove tail with the 130PDS as it already has one)
    • T ring for your DSLR: 20 Euros (camera make and model specific; you will not need a t ring adapter with the 130PDS)
    • Interval timer: 25 Euros (EBay.co.uk) Cheap no brand from China will work great

    This setup will let you get started with unguided exposure times of around two minutes or so. The mount can be upgraded over the years to allow for guided exposure times of hours. This means that just about anything in the night sky can be photographed with this setup; thousands of objects.

    The lowest cost (initially that is) option is a computerized alt-azimuth mount with a short tube refractor. This setup will allow you to do 30 second unguided exposures which is good enough to photograph the brighter Deep Space Objects in the night sky, perhaps 500 to 700 objects total …. Enough to keep you busy for a few years. This setup cannot be upgraded and will cost you about 445 Euros (plus ~40 Euros shipping from Germany). For an example of what you can photograph with this minimal set-up visit my Flickr Site; many of the images were made with such a setup; see: https://www.flickr.com/photos/59237884@N08/

    • SkyWatcher SynScan AZ goto mount: 245 Euros
    • SkyWatcher StarTravel 80 f/5, 400mm refractor: 130 Euros
    • Dovetail: 25 Euros (this is needed to attach the startravel 80 to the mount)
    • T ring for your DSLR: 20 Euros (camera make and model specific; you will not need a t ring adapter with the StarTravel 80)
    • Interval timer: 25 Euros (EBay.co.uk) Cheap no brand from China will work great

    As you can see the least expensive setup is limited to azimuth mount astrophotography and is about half the price of a setup that gives you far greater capabilities and room to grow in time. With the least expensive setup, if you want to go past what can be done with very short exposures, then you will have to buy a mount like the EQ5GOTO mount. However, in my opinion, this is not really a bad thing as you will still have the lightweight AZ mount that is extremely portable. It will be easy to backpack with low cost setup to a dark spot high in the mountains where the night sky is so dark that zillions of stars seem to fill the sky …. That is why I take my SkyWatcher AZ goto mount and 80 mm refractor with me when I go to our village Steno near Lake Doxa in Feneos. For more about astrophotography with alt-azimuth mounts see this sticky: Astrophotography with Azimuth Mounts

    One issue with the low cost option is visual observing with an 80mm short tube refractor. This telescope provides beautiful rich field of views and is very good for viewing a wide range of deep space objects. For solar system objects it does very well with the moon but planets will be tiny, very tiny… about all you can see is the equatorial cloud bands of Jupiter and the rings of Saturn. It makes a great portable second scope for visual observing but is on the small side for visual work if it is your only telescope. On the other hand, the SkyWatcher Explorer 130PDS will provide even better views of deep space and will also do a bit better for solar system objects. It is well worth the additional 50 Euros that it will cost. The SynScan AZ GOTO mount can easily handle up to 5.5 kg total payload. If the Explorer 130PDS had been available when I got my short tube 80mm refractor, I would have gotten it instead.

    Another issue is that the StarTravel 80 does not come bundled with a mount meaning that you have to buy the telescope and mount separately. This adds to the cost. For the same price you can buy the larger Startravel 102 bundled with the SynScan AZ goto mount. The larger telescope is much better for viewing the night sky including solar system objects. However, for some reason, the StarTravel 102 has more issues with chromatic aberration than does the StarTravel 80. For visual work, this is not a major concern but it is for photography.

    Links (note: The Germans tend to have very low shipping costs while the stores in the UK for some reason charge significantly more for “handling” costs to Greece.) All prices include VAT

    I own a heritage 130p.
    Dslr and the focuser is just nasty.
    1 - it is not designed for the weight of the dslr and can sag which will affect focus and collimation.
    2 - it is a bad style for focus adjustment. Trying to turn it with a dslr hanging on is clumsy.
    3 - to reach focus you have to drop the trusses about 3 inches.
    4 - it won't focus using a barlow.
    I used a cabin 1100d and took the Moon.

    Planets are much easier captured using a web cam and this is much lighter in the focuser.

    If you can get over the hurdle of the focus unit and have a light dslr then trying will only cost you a T adaptor and mount ring. Just be mindful that you can only do short exposure and you have no ability to combat field rotation.
    You could build a motorised equatorial mount for it if handy at diy. Then you get longer exposure capability and just be left with contending with the focus unit.
    Just sharing my experience.

    I will add that my canon weighs 495 grams so not heavy heavy and some dslrs are lighter like a canon EOS-m.
    I did not personally notice my focus arm sag with the camera but I could imagine it might.
    Because of the focal length ends up twice that of a camera lens you really are going to be using short exposures.
    Do you already have a dslr and lens?
