Hi, maybe there are ways to improve your scope the way you want it: in single stack best is to use the scope how it is. In dual stack mode there are uV IR KG3 filters that are more then 2x brighter then the blue or the previous blue green BG filter. However, I have never heard a review ( only from a Lunt 40 scope) .  Maybe Another more effective way to improve your scope  is to use A DS filter with your blocking filter and a refractor with longer focal length, same aperture but without all the extra filters from your alpha h scope! Maybe I will try this once .

Okey.....differences seems very normal in solar telescope due to complexity and small deviations in the production.  I thought once that it had to do how bright the scope is or how ALL filters in the system works together. Yea...seeing can effect every telescope in their own ways

Sometimes I have the feeling that (generally)  some 40 and 50 Lunt's show better prominences then some Lunt 60 , while the SD is generally better in the 60. (It's like that there are some advances and disadvantages beteen all units or bunch to bunch)  And then... better seeings helps too "solve" this, but less common. I am happy with my Lunt, am using up to 60x with zoom. But it's quite clear that the surface detail makes a better impression generally. 

So, if you have an DS 50  mm and BF1200 you can make also you own solar telescope.Only thing you need is a 50 mm refractor / achromat telescope with 2" focuser....right?  Thanks.

Thanks! Looking forward to add a DS filter this summer! 

Hi, If the prominences are just OK and the views of Surface detail almost 2x better...than I will go for it.  One thing about the tilt 60 and 50DS in comparison with an 50 mm Lunt scope, while the aperture is going down to 50 mm, the sweet spot of the 60 is not changing according to other forum's. You are right I have a 60 mm scope, I should save for the 60DS. The images are stunning! Thanks.

Hi, some are saying that the proms looks even better ( Lunt 60 + 50DS)  with the DS unit , the background is darker but you have to put a black cloth over your head and let your eyes get somewhat dark adjusted . Is this true?  And 2) is it worth to save your bills for the 60 mm DS instead for the ( for me about € 1300 cheaper)  still available older 50 mm model?   Is it also true that the DS 50 is a bit less sensitive for seeings ? I have the tilt telescope, don't know if that matters.    Thanks.  

Hi, I asked Oliver from beloptic. The filter was  specially made for the Lunt 60 tilt with50 DS if you want a brighter view for both visual and imaging. I will give it a try....ll'l see if it worth or not.

Or maybe with the combination double stack & bino viewer....

Hi, maybe you are right. Resolution stays the same, when the views are too dim still, then I will try the 20 mm IR/UV KG3 filter from beloptic.

If nobody use this filter ( KG3 ) for visual use, ( safety first) I will use just the standaard filter.

surprising,I thought that you could need more brightness with the 50 mm double stack for more magnification and brighter prominences ...no idea how dimm the views  with the double stack 50 is... thanks for your suggestion. 

Hi,  I just want to know if a IR/UV KG3 from beloptic is worth to use with an 50 mm DS etalon for Lunt 60?  I know for single it's way too bright... and what are the differences with the original blue filter?  Thanks for the tip.  

Thanks....I never use glasses when I am viewing.   

I also have a choice between 12 mm celestron XCEL and the 11 mm ES eyepiece. I wonder if the glass in the 11 ES is not a little too small for viewing? (and less comfortable then the 12 XCEL ?) Thanks for the tip. 

Hi, I want to use a 1.25" filter in my lunt bF1200. What adapters do I need for this? And, what I most do with the current 2" tube, as this is important to reach focus. Thanks for the complete tip.

Hi, and which of these is the best choice for an alpha- h solartelescope?  ( 12 mm XF or 12 mm vixen SLV for Lunt 60 tilt) thanks.

• Update: Hi, i think I find  my own ideal answer: "don't pay  €250 more for just a little better image quality and just a little bigger image, except when You have enough money" .  Thanks.

The 15 mm starguider Seems a nice eyepiece for a Lunt 60 solar telescope To start with think! ( 20 and 15 mm)  (A bigger image then 12 mm has no much sense I think.) staying with the 15 focal range, there is also an 15 mm TV delite. I also believe  that the image through this 15 delite eyepiece is also a little bigger then the 15 starguider ( 14.2mm vs 15 mm? based on a "Test" with TV plossl vs normal plossl)   , so maybe this 15 mm delite would be a nice  "best one"  ( image quality and size wise)  together with a simple 20 plossl for a normal Lunt 60 tilt..?) thanks for the tip.

Correct. So, does all pst's has this small sweet spot? And not able to see all the details at the same time too? If so, then an upgrade will be worth? Or should I stick with my pst even with it small sweetspot and medium magnification, And patiently wait at acceptable seeing and more exiting details, which may will help to ignore an further upgrade? anyways thanks I will think about it.

Hi, this  clearly show that there  can be a big difference between solarscopes.

And a bigger apeture alone will not always say you will use higher magnification! 

My guess is that you most have some luck with solarscopes. I now someone even with his Lunt 50 double stacked he could use relatieve highe magnification! And some pst's did better for higher mag then some Solarmax 60 11! And visa versa .

Hi, I always tune at the things I will look at, but never all the details at the same time. I can see about 40 percent of features at the same time, and have to move the scope to see the other details. Again , maybe this is also something that can vary as brightness , bandpass....your pst may be different then mine?( Meade pst buy in 2017) 

20 mm plossl and TV plossl 15 mm. I have heard that the pst has a small sweet spot but maybe this can vary from scope to scope? Do you always can get full disk with your pst?

Hi, I can buy an used maxscope for 650 dollar ( in good shape according to the salesman) the main reason for the upgrade is that I can't  get  " full disk"  with my pst. Let's say About 40 percent .(and 32x max used magnification in my area) How good is that maxscope 40 and does it give full disk visually? Thanks.
