Two and a half straight weeks of clouds and rain prevented me from taking this out of the box. I typically don’t review equipment that I deem expensive but in fact this is likely the cheapest and best option for solar imagers on a budget. At 400mm you get a nice framing of our Sun. There’s a bit of a focus learning curve but otherwise very easy to use. I was especially impressed visually. It’s the second dedicated solar instrument I’ve had the privilege of seeing thru. The price point is high but considering other similar marketed items it’s quite reasonable. The small 40mm aperture should not discourage an enthusiast as you know how bright the Sun is. I was impressed with it and see its potential to produce amazing photos. It’s unfortunate that you need to do some gear hacking to get a DSLR within focus range. You will have to settle with a webcam with a barlow element screwed into the nosepiece otherwise. I was really hoping to share video as I saw it visually thru a 9mm. Quite beautiful. Questions encouraged. Clear skies.

Great question. I honestly can only speculate the answer is no. It’s design permits only a fraction of our Suns light. I will pin this question in hopes someone can answer you definitely.

@@GarnettLeary NO!!! It is a SOLAR telescope. The SolarMax 60, 70 & 90mm all have removable Etalon filters and the diagonal requires swapping with a standard diagonal (don't forget to change back) leaving you with a 400mm standard telescope. The Coronado diagonal has UV/IR blocking filters built in and must be used for solar viewing.

I live in SLC area and use my PST every chance I get. I use the Coronado AZS tripod/mount which is lightning fast to plop down, point and view. The worm head movements are silky smooth after lubrication and initial adjustment. Tripod is very stable, light and fast to set up. PST is Happy!

They have since made several variations. There’s the Solarmax also. My preference leans toward a Daystar Quark. It is amazing don’t get me wrong but there are better technologies available. I think this one is the most affordable and it definitely is the pioneer.

The difference is huge unfortunately. There’s a lot of products that take you up in price. Unfortunately this is the best bottom option. Alternatively there are special filters like a Baader Calcium K-Line which are slightly cheaper. A pst is perfectly capable of getting the job done even scientifically but there are better scopes that resolve greater detail. If I had it to purchase again I’d go with the midrange Daystar 60. My main interest is in Sunspots by which simple mylar is enough. Check out Chucks Astrophotography and look at the videos of prominence he produced. Amazing. Don’t forget Novembers Mercury transit. I look forward to your next video and don’t hesitate to correspond. It’s nice meeting folks in this hobby and study. Clear skies.

@@GarnettLeary I went with the 80mm DayStar solar scout. I love it! I think just getting the daystar quark is the best option. Then you can use it on any refractor as opposed to having a dedicated H-alpha scope. My only complaint with the solar scout is the bullet finder isn't really accurate. I have more luck lining up the shadow of the tube on the ground lol! I haven't tried to adjust the finder, so maybe there's a solution for me. Clear skies and happy viewing!

Nice video. I was looking for some tutorial and after long wait I got your video online. I just have a query of mine - I have the standard eye piece that comes with it and struggle a lot. Should I use a zoom eye piece (8-40mm) or 5mm etc to get first light? Unfortunately, I do not have eq mount so using my DSLR low budget aluminium tripod that is not good.
@GarnettLeary

A 6mm provides a tight view. I was favoring a 9mm. I would stick with a prime over a zoom. You don’t need a tracking mount to film the Sun. The field of view is wide enough that you can get video clips as it passes through. Of course tracking would be easier and would be necessary for the upper end stuff but you can make perfectly good images untracked. As for visual a good ortho would likely dominate.

@GarnettLeary

Webcam, standard 1.25” webcam adapter nosepiece, and a x2 threaded on the end. It’s a perfect match. The barlow is sitting directly on the bottom. I was using a Meade shorty x2 lens element but have zero doubt any other brand removable would work. Furthermore I would venture to say a sawed off standard T-ring adapter nose piece on a DSLR would work as long as you dropped a barlow element in the PST. It wasn’t off much. Maybe less than 1/2” from focusing. I considered cutting the PST tube down. That’s a dangerous move tho. Not good for resale lol.

If the front lens element is not compromised you will be fine. It’s very well made. I’m not encouraging trying but a momentary glance into one that’s broken would be extremely painful and disorientating but doubtfully would result in your eye being burned out.

Can you observe the features of the sun visually in the telescope or do you have to image them to observe them ?
@GarnettLeary
@GarnettLeary 5 жыл бұрын
Great question. You can actively see sunspots or tune it to see the prominence. Imagine if you will the static on a tv not tuned to a channel. It’s faint and no real significant detail with your eyes only. Don’t expect what you see in this video as the webcam I used greatly magnifies the details. I would venture to say this telescope is more of a scientific instrument rather than a visual one. If your aim is to collect data from our Sun it’s a worthy investment. If you are only into visual use it may quickly lose its value. Beautiful images can be made with it but for that there are larger, more powerful, solar scopes available. If you’re interested in some amazing work check out Chucks Astronomy. Clear skies.

I own a pst and I also have a double stack. This means adding a second etalon filter which gives more detail. The pst on its own is a great starter scope for h-alpha solar observing. All h-alpha scopes are expensive, that’s just how it is. Do lots and lots of research before buying anything. One last thing. As mentioned in the video, having a tracking mount of some kind is highly desirable. Otherwise you will be constantly trying to adjust the mount, adjust the focus and adjust the etalon for details. This kinda takes the fun out of it. Enjoy.

The reason we don’t “look” is because our eyes aren’t as sensitive as a camera sensor. Trust me when I say I have spent endless hours looking. The thing is that astrophotography picks up where the limits of our eyes leave off. I totally love your question and totally understand it. It’s the question you ask just before you enter into astrophotography. Human eyes are limited. Look upon a target you like wether it be a variable star, a planet, or a nebula then let a long exposure from a camera sensor reveal more to you. It’s an amazing transformation. I am not mocking you nor trying to jump your comment. Try it. Clear skies and thank you for inspiring me.

I bought a used Coronado PST (Meade). It is a 40mm f/10 H-alpha telescope - 400mm focal length - 0.5 Angstrom. (external tunable etalon).. 2 questions.. 1) Looking down front of the tube and when I turn the rubber tuner, I can see a slight shift in a lens, moves up-down slightly depending which way I turn the focuser. 2) I noticed a slight faint dark area when looking in the eyepice as I tune the scope. It does not degrade the image or make any double images. 3) The screw under the rubber part will not tighten, seems stripped, wondering if any solution to this, I removed the side plate looking for rust or anything else and it is just pristine inside..lenses are crisp and no problems... So, basically, is the PST supposed to be this way, forgetting the screws but #'s 1 and 2.? To ship it back to USA from Canada.. well.. lots cash. Thanks in advance...

@GarnettLeary 6 жыл бұрын
I’m guessing it has to do with the etalon. You have to have some way of adjusting the wave. That’s a great question. Daystars Quark is the next go to. I’m not even sure how that works. Haven’t researched it. Chuck uses it and is getting amazing results. There are what’s called K-Line solar filters but they are high. The more you look tho the more you come back to the PST as entry. I would prefer greater aperture but then again is it really necessary? Taking a stab further at it I’d say the very narrow H-a transmission of such a filter wouldn’t universally pair with different cameras etc. That’s my overall best guess.

@GarnettLeary
@GarnettLeary 4 жыл бұрын
That depends on what part of the Sun you are interested in seeing or imaging. A typical white light filter will resolve the photosphere. You’ll see sunspots and it’s the most inexpensive approach. A dedicated solar scope will see the chromosphere. You’ll get surface details and prominences. There’s also things like the Daystar Quark on the market. Additionally there’s Calcium k-line filters. If you’re happy with just sunspots try a white light filter. If you want more intensive details you’ll need the others. I hope this helped clarify. Clear skies.
