Being a single father of three disabled sons it was only when I retired last december and not smoking that I could afford gear.

Sold my PST that to be honest was rubbish, just could not get a decent image, ME not the scope, saw one of these in use, sold PST and got the skywatcher 72mm ED and the Quark Daystar, mounted on the evolution mount from my ED EDGE Celestron

Have fun Skyhawk with your new solar set-up.
I have two PSTs. One is used as normal and also in double-stack mode with a Lunt etalon
( LS50F ). The second PST is a stage 1 mod, attached to a 70mm/f.10 refractor.
A problem with the PST is that etalon quality can vary considerably from one to another. It's been said that about 10% of PST etalons are excellent, while 50% are good, and the rest are poor. Mine are okay.
What some users don't like about the PST design is its quirky focusing arrangement. It can introduce astigmatism. Also, the IR blocking filter, sooner or later, clouds up. This is due to humidity finding its way into the laminations of the filter. The BAADER 35nm filter makes an excellent replacement.

It is just a REAL pain to get the images, It was a good scope, I had one when it first came out and sold it last year in MINT condition, no rust, regretted it and bought another 5 months later on ebay, then I got to use the Daystar Quark, on the same day I had my PST out, it blew it away, I had one just visible CME in the daystar there were FOUR brilliant ones.

A good PST can produce superb results, as Smerral has shown us with his double-stack PST imaging.
Using a handheld compact camera, I was able to take a sharp image of the last Mercury transit.
The planet shows no bigger than a full stop, with two small limb proms, and dark filaments on the face of the Sun.
A main attraction of the PST is that it can be easily modded to a bigger aperture 'scope.

Yes but I don't want to MOD, I can attach the Daystar Quark to ANY refractor from 60mm to 6", and the quality outstrips a PST as good as PSTs are they are 40mm and extra expense and trouble is needed to mod them, and I can't be bothered most people can't be we want a good setup from the start.

Also like it or not a double stacked PST has a much dimmer image when viewing, at least I am speaking from years of experience

A problem with the Quark is that it requires a power supply. Your previous PSTs might have suffered from poor or mediocre etalon quality. There have been reports that the Quark can also vary in quality of performance. There are some fabulously detailed images of the Sun taken with the humble PST, with and without double-stacking.
Is it necessary to have a D-ERF ( Energy Rejection Filter ) on the front of a refractor when used with a Quark?

No an ERF is NOT needed on a 120mm and under though you can add a 2" between the scope and diagonal if you want, and there are no problems with a power supply that I see, NO solar scope is perfect in fact NO telescope is the be all and end all, the Quark can easily be used on my 72mm, 80mm and 120mm giving me three solar scopes, so benefits outweigh any other concerns

I never said there weren't great images from PST's................. did I ? I said they are not for me.

How does the Quark handle the intense heat from a 120mm aperture refractor?

Ask daystar how it works, I have no idea, see their site

AND I did state "though you can add a 2" between the scope and diagonal if you want"

to me

Jeremy,

Refractors 80mm: no ERF is needed.

Refractors above 80mm up to 150mm: must at least have a UV/IR cut
filter/ You can use a front mount ERF if you want.

Refractors above 150 & SCT: must have a Front mount ERF.


You can use a UV/IR with your set up.


Tiffany

I have nothing against the PST except that I found looking through it and imaging very hard, even with a 4x binomate or 2x barlow, the Daystar is a LOT easier

Here are two of my images Patrick used, from a PST, real pain to get
