Lunt LS50 /600 vs LS60/600

Post by nebulabru »

Hello,

Some years ago I had a PST 40 SS, the image was dark and lacked contrast and brightness, I did not like anything, I sold it and I am very discouraged, now I want to return again to the H-observationalpha, had thought to buy a single Lunt LS50 BF600 PT.. but I see that the price difference with a Lunt LS60 BF600 TT is 400 euro (I live in Europe), and I would like to know your opinion in the sense if by that price difference ,really the difference in the solar image(and I am exclusively visual observer, not photographic) is large..., or rather those 10mm aperture do not say much.. very kind for their opinions.
Nebu.

Hi Nebu

When all other variables are the same, it's a very simple matter of the more aperture, the better (up to a certain extent). If you have the budget for it, an LS60 will definitely be the better choice. It'll allow you to see more detail and use a higher magnification.

That being said, if you want to save some money and go for an LS50; that'll still be a good purchase. I have one myself and couldn't be happier with it. But the LS60 is still a step up.

I'd go for the 60 if the budget stretches to it.

Hi Nebu
I had the same decision in October. I went with the 60 for 2 reasons. The increase in aperture is 30% more which is significant. The second reason is the bandpass for the 50 is 0.75A and the 60 is 0.70A so a better grade etalon. I would say worth the extra money. Good luck with your decision.

Hi Mark,

¿ really ? I can not imagine a remote operated pressure tuner yet but i think I will tinker it out

:lol: :lol: :lol: :lol: :lol:

How much pressure is that chamber in bar ? perhaps remote controlled In and Outlet via solenoid valves ?

:?: :?: :?:

Hi Mark,

Thanks. That is good to know :seesaw

So they just use one single tube as In and Outlet. I guess that big box has a compressor then. Good to know.

Now they jsut need to adapt stepper motors to their golden knob tuner :lol: I found stepper motor with 6mm diameter and big reduction gears.

:bow2

Thanks for your comments,
I have really come to think that maybe the Lunt 50 with the later coupled DS (in the future) may be more interesting than the Lunt 60, at least for details on disk, and it would always be cheaper than DS the Lunt 60, right?

By the way, these two models, LS50 and LS60, can be used successfully on a photographic tripod (I have the Manffrotto 055) or are they "little beasts" for equatorial mounts?

Best regards
Nebu

If you are seriously thinking of imaging I would recommend the 60 with at least a 1200 blocking filter. It will be cheaper in the long run to get the most scope you can afford. You also might look into a motorized stable mount. Just my 2 cents.
