And I would bet that Don has more used telescope gear for sale than any human alive.

Jim has more stuff to rig out, replace or upgrade your telescope gear than any place on earth. It reminds me of Jim Henson and ScopeStuff. What is it? Heck, I don’t know, but if its from telescope pioneer Thomas Cave (I didn’t think he was even around for the Dob revolution) it’s something you and I may never get to buy ever again. Take the listed Cave 10-inch f/5 Dobsonian. Yes, he has virtually every name brand scope, mount, eyepiece and more, but he has some seriously out there stuff as well. When you go to his website, trust me you will be overwhelmed by what is available. The reason I am writing today is because when I ran across Don Rothman’s site, Astro Parts Outlet Used Telescopes, I realized that any ambitions I might have as a trader were dwarfed by Don’s pre-owned astro-tech offerings. In fact, I should have been born in another century, traveling the Trans-Saharan Trade Route from North Africa to West Africa with a caravan of camels trading ostrich feathers, salt, gold and more (you’ll have to Google it to see what I mean).īut I digress. If you are interested in used telescope equipment, we keep an ongoing list of equipment available on our website here.*** *** Editors Note: Since the publication of this article, Astro Parts Outlet Used Telescope has suspended its operations. Anyway, in summary, buying this is a no-brainer if you want to view/photograph sharp, detailed images of the sun, including convection cells and sunspots.Ah used telescope stuff! I have always enjoyed finding a deal – boats, cars, jewelry (for my significant other of course), and yes, telescopes – well you name it, I am into getting a deal. It's the results that count not how amateurish the filter looks! My filter is being used on an old TAL2M telescope and in the 20+ years I've owned this telescope, I've never been more impressed with any image it has produced. For the price of a sheet, I would perhaps suggest buying two for that reason. Different ball-park price-wise though! Okay, building the filter is a bit fiddly, but now that I've done it once, I feel I could do it again in half the time and have a neater looking end product.

My sun photos are now, to my eye, of a professional standard and could only be improved with a hydrogen alpha scope. The packaging claims the optical quality to be equivalent to glass solar filters and I without doing a comparison myself, I do not doubt for a second that this could be the case. This solar film is, if you pardon the pun, night and day compared to earlier filter types I've used, such as mylar film. Safety is everyone’s responsibility - please read the safety notes supplied with the product carefully.

Especially with an orange sun, it is very hard to see faculae regions which are visible predominantly in the blue wing of the spectrum.ĭue to its neutral colour balance, AstroSolar enables the use of various colour (or interference) filters which allows the observer to concentrate on certain spectral passbands for investigations of different layers within the solar 'atmosphere'.ĪstroSolar™ is essentially free from pinholes, since - other than with even the most expensive glass filters - it is coated on both sides, so that the chance of two pinholes overlapping each other is extremely faint. Other films and most glass filters produce a blurry bluish or reddish Solar image, thereby cutting part of the spectrum. With AstroSolar™ the Sun appears in its real colour - neutral white. Roll: 100 x 50 cm Baader AstroSolar™ film This foil is CE-tested and reduces the intensity of sunlight by 99.999%. Baader AstroSolar Safety Film is made for the construction of high-quality objective-filters for observing the sun with telescopes, binoculars, camera or video-lenses.
