You can make your own. Go on surplusshed.com and pick up one of the 1/20th wave mirror flats. That is the best you are going to get for next to nothing. For the housing just buy a cheapo on ebay and take out the mirror and replace with the new one.
Telescope manufacturing is simple. Find a supplier. Done.

I can highly recommend the Istar's diagonals. see my review on Istar website. when seeing allows it will show you what your optics will pass. it will be one less thing to worry about. get one and have fun. I bought 5 five of them so far. everyone that tried them won't give them back. Great product!!

Hello Paolo, Not sure what you mean by "claimed." Did Ales say he was working on an 8 inch F8 tube scope somewhere? We do have a 204-8 TCR in R35 but as far as I know there is no intention of producing an AXT tube model. I know we are going to eventually change our lenses over to the new design R45 but we have not produced any yet.
Skybender is a optical filter tilter, the first of its kind in the world. You can use this to view the sun visually, or photographically, and you can also use this to view nebulas, galaxies, and supernovas utilizing a new phyiscal method of color rejection.
You can apply blue shift to all bandpass and dichroic filters, by tilting them. This affects the glasses index of refraction, much like a prism does, and instead of seeing a complete rainbow you are seeing selective narrowband wavelengths. Each narrowband wavelength less than 1nm represents a set of ionized-elemental-gasses (excimers), and absorption properties of light behind gasses in nebula/ galaxies/ clusters. (light has literally a direct representation of various elements within the periodic table of elements, based on their emission/ burning/ ionization etc.)
Also possible is the strong desire to try, but there is rare chance. You can selective tune out various backround levels from supernova, and record the event based on its "metallic output" If you find a optical spectrogram of various supernova, you will see that the biggest ones flare out somewhere around 850nm. The spiked output directly represents a huge chemical/nuclear reaction, (of excimers), producing some type of calcium release... ( it is definitly Ca2)
99% uv optimized 40mm objective lens, Coronado telescope brand - 25.4mm internal narrowband 2.2angstrom filter, Lunt solar systems brand- 34mm objective mountable 2.4 angstrom filter, (can also be used in the focuser) william optics ddg focuser with blue matching thread for my gold tube
This is truely one of a kind instrument for solar observation.
working 70 hours a week for 7 months got me this grab and go.
You have several posts on this website including your first teaser photo of an assembly on your workbench. I also looked at your link to a forum thread with titled PST modifications. Can you provide some details of this product and how current Istar owners can utilize it?
hmm that skytracker has a powerful resemblence to the vixen polarie, on a side note, hey mike i can have a batch of skybender made for canon cameras... Thats on my list of thing to do, what size lens are you working with 58mm?
