A copyright claim has been filed on music I've already paid for again :( This issue keeps recurring and it's frustrating to resolve. YouTube offers the option to replace tracks with music from their free library, which is helpful, but it disrupts the video (It cut me off speaking then ended abruptly, plus it's loud!). I apologize for the loud music at the end; unfortunately, there's no way to adjust the volume when replacing a track.

Sooo, does anyone else's mind wonder to Solar during the summer months?

Neat looking little gizmo.

Hi Chris great video again mate, good to see the suns getting a lot of attention at the min

I've looked through one of these, the view is mesmerizing. Thanks for sharing mate!

Nice intro into solar observing. I've got a Lunt LS50 THa, had it for nine years. I prefer solar observing and imaging to Lunar and planetary because of the dynamic nature of the sun, it constantly changes and has been pretty awesome of late. I know the planets are dynamic too but I don't have a telescope with sufficient FL to see them at their best.
I usually use a Star Adventurer mount with my LS50 which I find perfectly adequate for solar observing or imaging. I also have an Altair Herschel wedge which I use with my William Optics 81GT for white light observing and imaging. I've used Baader solar film in the past and even used a ípair of 8x30 binoculars to project an image during the transit of Venus back in 2004, I was at work at the time so could only view it during break periods.

Brilliant video, so well done! I just purchased a double-stack version of this device used, and can't wait to mount it up. I appreciate you going over the history of the PST, and the various tips you mentioned like the quirky back-focus issue with cameras and such. Thanks!

Hi Chris , I too am interested in this scope ... Really like the idea of pairing it up with a solar wedge . Glad you are showcasing it mate . Your reviews are ALWAYS a good watch .

I was hoping you would do some video. Thanks!

Just got my first H-alpha scope (Lunt LS50THa) about a month ago and I'm loving it!

I've been doing WL solar observing over the last year using a Lunt 2" Herschel wedge in 70mm f/6, 102mm f/7, & 125mm f/7.8 refractors. Adding hydrogen-alpha to that with this little 50mm f/7 Hα scope has been awesome, especially with solar maximum ramping up.

If anyone has been entertaining the idea of giving H-alpha a try, now is the perfect time to jump in!!

realy interesting thanks

My Solarmax 60 II double stack is still almost unbeatable.

I turned a 50mm B600 Lunt into a 102mm. To do this, I just unscrewed the Etalon with the blocking filter, shortened the telescope a bit, and attached it to a larger device with a 110mm ERF in front. double stacking was also possible, a friend of mine have it tried, with a daystar quark instead of the blocking filter.

I have one of these scopes. had it since it came out late 90's. I had to send it back to get recoated when Meade took over. It was done under warranty. Have back out as solar max approaches.

Really good summary of the PST. I've been using mine again recently both visual and with a little mono camera (Basler aca1920-40 and 2.5x powermate) with some good results. I have a Touptek G3M678M on the way which I am hoping to be a good fit for the PST, it should get the full disc in the frame and pixel resolution is almost a perfect match, maybe 10% oversampling. The only reason I went with the Touptek though is I had no idea the front of the ZWO could be unscrewed to get closer focus (not sure the ZWO 678MM can do that though).

I would only add one thought : not sure if you are using a colour camera or not, but you loose resolution and sensitivity when using a colour camera vs mono : it is such a thin wavelength of "red" through the scope, so the green and blue filtered pixels on a colour camera aren't really doing anything (on a standard Bayer mask colour sensor, only 25% of the pixels are collecting photons when imaging Ha solar).

Also, I've had mine years now and totally didn't know about rotating the collar for tuning, I will have to try that next time I use it, thanks!

Have you tried the 60mm daystar same price range amazing views would be nice if you could compare them

Hi just got one of these PSTs and just tried it, can’t see any change from a red sun to Red sun other side of the filter wheel, not sure what should happen when the filter wheel is turned.

Ah the PST's I had three & a Lunt 35 which my other half seems to have claimed lol, I gave one of the PST's away not that there was anything wrong with it just to get rid of some stuff as I used to do mainly solar outreach until covid came along then other health issues so haven't done any for 5 years now. One of the PST's I have does have a double stack that I can fit to it although most of the time I generally don't bother using it, the other PST is a CaK version which as you know is useless for visual but it still images pretty well. The best solar scope I looked through was a Lunt 102 which made the PST's look like a toy in comparison even though at the time the sun wasn't very active back then the detail it was showing was insane. I have often thought about getting a PST mod scope built but that's still going to cost a lot of ££££££££££'s but I did look through an 80MM PST mod at one of the stargazing lounges star parties (ah how I miss those)
Clear skies

Love the video man. I just got a used Coronado solarmax 40. What tracking tripod do you recommend? I rather have the sun in view at all times instead of playing around  trying to keep it centered.

May I inquire...to anyone who may see this... I have just found, well bought, one of these, with case and all the eyepieces for it etc for £300, is that an ok deal...also, i own like 13 scopes, iv used my 10" intelliscope, celestron 8se and dwarf 2 for solar pictures or viewing, was it worth getting this at all, will it show much better than have already etc??
