Hi, I hope that mr s ransden will do a new Comparison test with the PST! The new scope looks nicer then the prevIous Lunt 35 and the newer pst from Meade. That makes it tempting to buy it, smart move from Lunt! Thanks.

Hi,

I am not in the market for buying one but if I spend US $ 500.00 for 40 mm I would add US 200.00 on it and get a Lunt 50 mm which has 56% more aperture then 40 mm ;)

BTW the Lunt 40 mm looks less complicated then the Meade PST ... e.g. the Lunt seems to have a better focusing system then the Meade PST ...

IMHO

Generally I agree with Rainer but for example the Coronado PST with a focal length of F10 does better than my SMII60 does at higher magnifications. One fellow here runs his on average well above what I do on my SMII60. My 60 is an f6.6 if I remember right. One would think a higher magnification would be easier on the larger scope but the PST defies this, at least with mine. Not sure why.

So in this way I might have been better off getting the PST vs the SMII60??

I will take a 40mm telescope with a front mounted full aperture H-a etalon any day vs 50mm telescope with tiny 20mm internal PT etalon.

Hi Valery,

Thank you for that. I did not realize that the Lunt 50 mm has an internal etalon.

Shame on me and I should have taken a better look on the images on the Lunt website. Thanks for drawing my attention to that and right, beeing so the business I also prefer a 40 mm etalon then a inner 20 mm etalon.

This happpens when I do not yet had my morning coffee :lol: :lol: :lol:

Again thanks.

:? Hi, I think small scopes Have also their own charm. Both looks and views.whatever the thing or direction you will go is- if I believe the Previous reviews The Lunt 35 could handle nice magnification and had brighter views than ( some) PST's. If you want / love that then Maybe this one with its improve focuser and 40 mm apeture wold be even better. :?: If lunt do not mess with the optics And doing good quality control, this can be a verry good intro scope.

Hi James. I think Not all pst's ( and other scopes) can use the same magnification too. ( maybe you could try to put another Better quality ITF in your scope if you love higher mag, instead of looking for another " verry good " model) whatever the thing is, I hope that Lunt know this and made all their new scopes equally good.

Many here suggest that Lunt is more consistent in quality than Meade Coronado with better customer service.

Thanks Valery,
I was thinking about buying the Lunt 40 mm which is quite new and advertised at 599 USDollars. Has anyone got any sample images to see the quality of this telescope.
I agree Valery that a front mounted etalon is better, but does not one also have to consider costs.
Although I could afford a much more expensive scope, I am not sure if it is worth it if I only get 1 or 2 days of good imaging a year ! For example it has been cloudy and damp for months in London. I could consider spending 80000 pounds on high end mounts and Etalon filters from Solarscopes in Isle of Man, but may find it gathering dust and may be malfunctioning in the home during at least 90% of days in the year.

I would like to see sample images to see how this compares with a 60000 dollar setup.

Many thanks

Magnus,
It does make good sense buying a smaller and less expensive scope versus a larger more featured bigger one if you are not going to use it often or weather/climate won't allow you to do so. A scope that sits most of the time is of little use. It's sort of like buying a big dobsonian if you live in the middle of the city. You might travel occasionally to a dark sky site to gain the full advantage of it but otherwise it just sits. The observer would be served far better with a smaller grab and go scope for his/her urban environment. It would be used far more often.

Magnus, James has perfectly explained the reasoning for only buying a smaller/lesser-priced solar-scope, so I can't see to advise you of a better answer.

Hi Magnus,

My thoughts here. All Ha scopes are different and perform differently even if from the same line up (eg the 40mm you are talking about). A picture someone takes with a scope in no way representative of what you might get in your particular sample.

Variance in Ha scopes across all manufacturers seems to be large. Comparing even from the same line up is comparing apples to oranges. Ha scope buying to me is a lottery, that is my 15 years experience of it.

Hi,most Important is the quality of the etalon and the way they are put together.( also that red glow) Whether it is full aperture or pressure tune. It's still not clear which scope's has generally the best etalon and how they vary and why?-but assume that new Lunt 60 MT and Lunt 40 has genarally good ones(? At last they have the same "time line" with the production) I also believe a few years ago meade has Made a new series pst's with relative poor quality etalons. ( to save money, production problems?) and if they are both good ( you never know for sure!) , I would say go with the tilt tune for visual use and the pressure tuned model for imaging. But the differences are not big I think.

I am not sure about this, but I think a bigger Aperture ( up to 80 mm) should not be a big problem for viewing in average and better conditions unless you have a solarscope with a less good quality etalon!? Maybe also with this the quality of the etalon matters? Or you can al

Hi

Would be nice if they offer a DS add on as a separate product like on the larger scopes.

I bet in time they will since the competing Coronado PST has a double stacking option.

Hi, I asked Fay and at the time they don't have a time line established for the Lunt 40 double stack filter. Please check out their website for updates periodically.yes,the pst has a double stack option but also poor quality products. I think that even the double stack for the Lunt 40 would be better.nevertheless, I am curious how the competition will be and what the quality difference will contribute between them.

While I would agree that the Lunt 40 scope is almost certainly better than the PST I would not go as far as calling it " poor quality ". That little scope over the years has probably gotten more people into Ha solar than any other single scope out there. It has probably out sold over the years by numbers alone any other Ha scope out there as well. Modders covet the etalons out of them too! They might not be the best out there quality wise and may not be made quite as good as they once were but I wouldn't myself be so dismissive of that capable little instrument. Amateur solar astronomy owes a lot to that little David Lunt invented scope.

I almost bought one back in 2013. I wish I would have...

Yeah, the pst has maintained its characteristic charm, like the buit-in solarfinder. But are they still recommended for new buyers? Or does the pst have had their best time? Time will tell...personally I would say, if it is a very good pst- go with the pst but at this moment, go with "made in USA" product:the Lunt! ( I also wonder if the Meade 40 mm double stack filter was made in Mexico? Are there any differences with previous models?)

Re: Lunt 40mm Dedicated Hydrogen-Alpha Solar Telescope

Post by DeepSolar64 »

Andre,
I dunno. Most old timers in Ha say that Coronado isn't what they once were but I have two Coronados, a 60 and a 90 SMII. Both double stacked. I have had good service so far out of both of them and have learned a lot about the sun with them. I would love to look through a Lunt and hear they are on average better than Coronado. And I do like the fact that Lunt is a US product. I certainly agree with you there!

It's sort of a trade off. Lunt is better and Coronado cheaper. With me I saved a lot of money on Coronado Vs Lunt. My SMII60 only cost me 1750.00 for a double stacked system and my SMII90 cost me 3500.00 for a double stacked system. I couldn't even buy a single stacked Lunt 80MT for that price! Coronado has largely switched to the SMIII and I got the IIs on closeout. It was a no brainer for me. I simply could not afford the Lunt I was after, The Lunt 100. If it wasn't for the closeout price on those Coronados I probably would have went Lunt. Probably an LS50Tha on the smaller scope and an LS80MT SS on the larger one. I was in a way disappointed when Lunt dropped the LSTHA series dedicated scopes for the majority of their scope lineup for the MT Series. I simply did not need a multi-function scope in most situations since I have several nighttime scopes already and didn't like paying extra for a feature I would hardly use. Coronado worked for me and made bigger scopes possible but Lunt is certainly a good path to take. I still like the idea of purchasing an LS50Tha. Or a Lunt 40!

Good luck with getting a Lunt 40. Let us know how it does!

James


P.S. And the Lunt LS40Tha is inexpensive and US made and is a dedicated solar scope to boot!!

Hi, I just bought a used Lunt 60 tilt for just 800 euro and 200 tax.Here are a few advantage and disadvantages compered to the PST: + the Lunt is easy to use and the BF1200 give you a comfortable look. + details are more easy to See and relex to look at. + fun Crawford focuser. -(sometimes)the image are a little monotonous. - less portable then the PST. I start with 20 mm plossl and 15 mm BST and they did very well in these average conditions in autumn and I like to use them more ofthen- good detail and comfortable. the normal max usefull magnification of 120x, I can forget it. I guess around 60x max in decent/ good seeings.( even 33.3 x is more then enough for me- so far...I will test higher ones in the spring and summer) There seems to be variations in brightness in the coatings, dependent when they are made...that's why some scopes can only use 40-50 percent from the normal maximum usefull magnification I think.( apparently for certain things such as better protections in the Filters) so, I am very very happy with this Lunt tilt,good optics and also curious about the 16 mm Brandon eyepiece-and I paid less then a new Lunt 40 for it!
