I just (10/21/05) became the proud owner of the PST after one full

year of deliberation.



In order to observe greater surface detail on old "sol", I am

seriously considering buying a used, but LN SM40 ($700 range) to

doublestack the PST (but will go deep into "hock" to do so).



I have read that the new PST CaK MAY show surface detail matching the

SM40 doublestack, for at least $200 less cost to me.



I already realize that the view with the SM40 in place will be dimmer

than the PST alone. Anyone know if the views through the PST CaK are

as "bright" as the PST alone?



I have also read "contrasting" opinions as to whether the PST CaK is

capable of manifesting solar prominences. It would definitely lean me

in the direction of the PST CaK if in fact it brings out the larger

prominences.



One additional thought: I know that one major advantage of the

doublestack is that it is easier to see prominences and surface

detail concurrently. Can the same be said about the PST CaK?



While a PST CaK will save me at least $200, I am willing to borrow

enough extra $$ to buy a good used SM40 to doublestack the PST if its

views are decidedly/arguably superior to those of the new PST CaK.



ALL opinions are deeply appreciated! THANKS!

I own a double stacked PST which I love better than my 3500 Daystar ATM and

I have on order a PSTCaK but I STRONGLY suggest that you buy a SM40 and use

that for a while the PSTCaK is supposed to be primarily for imaging and you

may be very dissapointed you may write me direct at h-alpha@... if

you like for further dialogue I have been observing the Sun on a daily

basis since 1989...Ralph

Ralph,



Thank you for your answer. I was obviously confused regarding the

visual advantages of the PST CaK.



I will be in touch with you for additional insights.



Thanks again,



Dennis

Does your used SM40 include the T-Max tuner? This makes a huge difference.

PST+T-Max+SM40 gives amazing views.

Hi Dennis,



They're completely different animals. The lower chromasphere visible with

the Ca-K 'scope isn't nearly as active as the upper chromasphere you see

with an H-a 'scope. If you're wanting to see proms and more "surface detail"

then you'll be far better off stacking your PST. Observing in the light of

Ca-K is certainly rewarding but you won't be getting the same eye candy you

see in H-a.



Clear skies,

Bill
