California Denkmeier Spectrum 60 upgrade for PST       #3197454 - 07/03/09 05:29 PM Edit   Reply   Quote Quick Reply   Just saw the info in S&T on this. Does anyone have further info on it? Anyone take the leap yet or too soon? I would assume it would kill the warranty on my PST. Not sure that would matter too much with the stories about current Meade repair service quality. Denk is a reputable company and would not seem there is too much risk. For another $600 investment you get the added aperture, 600mm focal length, upgraded focuser knob, and an enlarged block filter. The picture of it does show an almost Galilean looking scope with this very long, slender tube. -------------------- Phil Agins 15" Discovery TD 10" Discovery PDHQ 5.7" Ceravolo Mak-Newt HD145 TEC 140, TeleVue-102 Vixen ED80Sf, APM-LOMO 80/600 Coronado PST, Lunt LS60THaDS50/B1200 Porta Mount, GPD2, Sphinx SXD Post Extras:       Don W Postmaster Reged: 05/19/03 Posts: 14567 Loc: Wisconsin, USA Re: Denkmeier Spectrum 60 upgrade for PST [Re: Cosmosphil]       #3197473 - 07/03/09 05:45 PM Edit   Reply   Quote Quick Reply   In keeping with our policy on modifying PSTs, I am going to lock this thread pending moderator review.

I wonder if the ITF filter was replace also? If that is so , anyone with a rusted ITF would worth taking up the upgrade, after all the cost of replacing the ITF is around usd100 already. anyone any info is the ITF was also replace? lee Post Extras:       Wes James Post Laureate Reged: 04/12/06 Posts: 3391 Re: Denkmeier Spectrum 60 upgrade for PST [Re: simonlee]       #3199578 - 07/04/09 11:05 PM Edit   Reply   Quote Quick Reply   Has anyone heard when he may begin accepting PST's for mods? -------------------- Wes Atlantic Beach, FL Some bino’s from Miyauchi 5x32 Binon's up through Garrett 20x110 Signature's, Some telescopes from a Stellarvue 80mm NHNG up through a couple of 8” reflectors… And a wonderful 4.25" Delmarva Shiefspiegler!

California Re: Denkmeier Spectrum 60 upgrade for PST [Re: Wes James]       #3200544 - 07/05/09 03:24 PM Edit   Reply   Quote Quick Reply   That's my question. Wondered if this is still too new or if anyone has updated yet. Maybe need to wait a couple of months from now to get any idea. All I can say is that for the money it does seem to be a good deal if Denk can keep to their level of performance they have in their other optical products. Wonder if they are sourcing the components or is this Denks own take on H-Alpha? If you already outlayed for the PST and its still in good working order (mine is serial# 103953, Meade built in Irvine, about 2 yrs old) then for essentially another outlay for a second PST you get into a whole other level of performance. My Lunt 50mm filter shows added resolution over the PST so I can imagine additional improvement from 50 to 60mm. This is something I while definately keep an eye on for future consideration. Especially after this weekend's encouraging solar display! -------------------- Phil Agins 15" Discovery TD 10" Discovery PDHQ 5.7" Ceravolo Mak-Newt HD145 TEC 140, TeleVue-102 Vixen ED80Sf, APM-LOMO 80/600 Coronado PST, Lunt LS60THaDS50/B1200 Porta Mount, GPD2, Sphinx SXD Post Extras:       warf scholastic sledgehammer Reged: 10/25/04 Posts: 781 Loc: Wisconsin Re: Denkmeier Spectrum 60 upgrade for PST [Re: Cosmosphil]       #3202309 - 07/06/09 02:39 PM Edit   Reply   Quote Quick Reply   Russ has done some work with Coronado in the past... if I am not mistaken, Denkmeier contributed to the SOL finder used the PST. -------------------- Marsh Celestron NS 11 GPS, Denk Standard Binoviewer, Pair of Denk 21 EP, Denk PowerSwitch Diagonal, Denk PST Corrector, Coronado PST Double Stacked, WO ZS80 Anniversary,Celestron 15x70 Binoculars Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 2 registered and 3 anonymous users are browsing this forum.
