Do you mean to tell me that JP there didn't first demand seeing test reports of the Istar lens from Wolfgang Rohr first?   Mike |

I've always maintained that you cannot buy any other maker's lenses with any higher performance level. I knew there was something "different" about my lens during it's first light. If anyone out there has any apprehension at all about going ahead with a purchase please, please do not procrastinate. If you do you'll only be doing yourself a bigger disservice due to the increased wait times that I'm sure are in Istar's future dealings.  Mike |

That scope and images are irrefutable evidence that Istar can build a great lens. JP is a seasoned solar imager. His experience qualifies him to make a judgment on lens quality. I talked to Jen, the owner, at Daystar and she said the images were extremely good and showed excellent resolution that only a "first" quality lens could deliver. No piece of paper or report of any kind could deliver the proof that first rate images do.

Those photos are really amazing, as is his scope. Funny, there is almost zero commentary on CN re this instrument. Kudos to ISTAR on this project.

Hello everyone,
and please, if you can, forward this info to the CN bunch as I have very little time to do such things.
Several people asked about reason why we used R30 glass combination on this superb 228 F9 Ha lens for JP Brahic, instead of using the more common flint and crown, those in our standard achromatic doublets. Of course some accused Istar of artificialy increasing price (why in the world would we increase prices when everyone else is cutting them down... ). The reason is much simplier. We have a large batch of R30 glass batch purchased for lenses above 180mm. Actually, in this case, the R30 combination on 228mm lens ended up even slightly less expensive then to buy a small quantity of standard flint and crown to produce this special doublet. The R30 mark was simply transferred from our paperwork to the lens cell, something I would stop if I knew about it in the first place.
I hope that this explains. Next time, even if we use the better glass on similar product, I will make sure not to engrave the glass combination on the cell...
best regards,
Ales
