Skywatcher Heritage130P FlexTube Dobsonian Telescope Black

Product Information

A 150mm f/5 is shorter than the 150mm f/8 of the Skyliner Dobsonian, and more portable for travelling and camping.

i am really impressed with this little scope, we can clearly see Jupiter's moons, Saturn's rings, and amazing views of the moon. i live in the countryside and we are 5minutes drive from a hill with a bench and no lights around, perfect to set up the scope We also measure the Power with our systems which is essentially the error from the reference sphere to the test optic. The reference sphere we use on our system is a very high quality sphere so the closer to zero the Power, the less error between the 2 elements thus ensuring a higher quality optical surface.The scope’s included red-dot finder works very well, especially given that this telescope is a wide-field instrument, so precise aiming isn’t really required anyway. The “Tabletop Dobsonian” Mount Im sorry to be asking another 'what scope shall i buy' type question as these seem to pop up all the time. I've narrowed my choice down to the fact im getting a dobsonian since its going to be my first ever scope and after contemplating getting a goto or not have decided to keep it simple (i like simple, lol) and learn the stars the old fashioned way. I had the Heritage 130P for a while and it's a great scope (it was the one I started out with). For that price you would struggle to do any better. The Meade is probably just as good (optically it is likely to be identical), but it more expensive from what I remember.

i have a well equipped workshop, i can weld, machine, 3d print, and i can program microcontrollers to drive stepper motors or actuators You will also see some more values such as Astigmatism and Coma. Again, these are measured by the interferometer when we take measurements of the optical surface after adjustment. These are values which ideally would be at 0 but as our test optics are all curved lenses, there will always be astigmatism and coma present. The lower the number, the less of these aberations you will effectively see but with most refractors, you can buy field flatteners which will compensate for the coma anyway. The astigmatisms value is explaining the error between the symmetrical curvature of the lens. Basically, no lens will be perfectly symmetrical, the lower the astigmatism, the more symmetrical the lens surface is.Saturn’s rings were obvious in the 25mm eyepiece, while there was a hint of the Cassini Division in moments of good seeing conditions with the 10mm. Its moons, Titan and Rhea, were also spotted to add to the fun.

We took a tour of the best summer Milky Way targets, beginning low down in the northeast with the Double Cluster in Perseus, using the 25mm eyepiece. I have been pondering between getting this EP or a couple Plossls to start. 13mm Nagler with a 2X barlow what do you think? my son wanted a telescope for his birthday and thanks also to the very good info i found here we went for a sky watcher heritage 130p Messier 22, the largest and brightest globular cluster in Sagittarius, was easily visible with direct vision and appeared fairly large and uniformly gray at 26x. Some resolution throughout the cluster seemed possible with averted vision, which became much more apparent at 65x.

One thing to watch for is that turning it too far will cause the barrel and eyepiece to become completely detached, but it’s easily reattached again. on a different note, i found a tip on a YT video about a thing to accurate focus, is basically a front cover with two holes The Heritage-130P has been specially designed to celebrate the International Year of Astronomy 2009 and the 400th Anniversary of Galileo’s first telescope. This is not only a highly functional precision optical instrument but also a beautiful collector’s piece and ideal gift. The telescope tube is adorned with the names of many famous figures that have made significant contributions to the advancement of astronomy over this 400yr period, including Galileo Galilei himself.

Obviously, at this point, you’re probably wondering why more scopes aren’t sold in this configuration. The answer is that it does inevitably come with compromises that not all users are willing to contend with. The first, obviously, is the large amount of stray light that can get into the tube. The scope does have a baffle directly across from the focuser that prevents light from shining directly into it, but light pollution, moonlight, and even the glare from bright stars can still get in around this baffle-or bounce off it, since it is rather shiny plastic. You can solve this with a DIY shroud, but this is, of course, an additional hassle and expense, and it’s still not quite as good as a closed tube.

Easy to use and very capable with a 130mm mirror making this an ideal telescope for anybody wanting to see the wonders of the night sky, you can be setup in seconds with this portable yet powerful instrument. i also tried through a 2x Barlow, i can then focus without retracting the secondary mirror but FoV is even smaller. The workhorse 2mm exit pupil, 65x eyepiece that is 10mm. This is for deep sky. It might be also 12, 11, 9 or 8mm. 10mm Hyperion or 9mm Orion or SW 66 Expanse were great, more comfortable than 10mm Plössl or 9mm Ortho. Nagler 11? Yes, of course, if you have the means. Also Hyperion Zoom (remember, comes to focus 16-8, unless you shorten the trusses). Delos and Pentax 10mm also but I didn't try them to know if they focus (they should)
