Greetings,
I am thinking about buying a single stacked H alpha scope from a local Lunt vendor here in Sweden - the internal etalon in the model he has in stock comes with a small tuning knob right above the Lunt label.

This is different than the (I think) more recent pressure tuned single internal etalon versions.

My question is: how well does this scope perform visually, and can it be double stacked later???

I need to give the vendor a decision soon if I wan this scope or not :confused:

Thanks for speedy answers :bow:
Cheers
Michael

works well - yes you can double stack
pressure tune gives a more uniform background but tilt on lunt works pretty damm well
here is a few pics same scope with 50mm DS

That is the same model as the one I have... works very well, no complaints here. You can retrofit pressure tuning in the future as well, Lunt does that for about $500 I think.

I love mine, and it's the single stack. You can see my images with it on my Astrobin site in my signature.

thanks for the info, y'all
rigel123: wow great pics through this scope, is it that crisp in the visual mode too? I think you have me convinced ...
so nobody thinks that the pressure tune model is so much better than the tilt?
Cheers,
Michael

Actually, I think the details are sharper visually, particulary on the proms, than in my images! It is like looking through any scope, the more you use it, the more your eye can pick up.

I can tell you that the first time I used the scope my mouth just dropped open!

If you haven't used one before, one word of advice: The draw tube where the diagonal is has to be pulled out a bit before trying to focus the scope. Two set screws are loosened, you slide the tube out a couple of inches, and then you use the rough and fine focus knobs. You might have seen another post in this forum about having trouble bringing this scope to focus!

rigel123: thanks for the focusing info - not sure though I can visualize this - do you have a pic?
Do you mean the diagonal tube, or is this the actual draw tube of the focuser?
thanks,
Michae

thanks for the important info

Thanks all for the motivating info

So I finally pulled the trigger and put in my order for the LS60THaB600C, a Baader 2" Herschel prism for my 120mm f/5 achro, Kendrik WL filters for my 127mm MakCas and little AT72 refractor, and a planetary zoom EP (7.2-21.5mm)
:yay: :jump:
This should allow me to get set up for a long Swedish summer, with an insolation, or I should say actual sunshine of at least 16 hrs per day, and with hopefully beautiful clear sunny days, with perfect seeing :cool:

Of course, if the skies cloud over, and we have the rainiest summer of all, I appologize to my neighbors for having brought on this curse
:tonofbricks:

Can't wait for the delivery tomorrow ...

Cheers all
Michael

of course the summer sucks for night time astronomy, but then there is the winter

Good luck with your new equipment.
We northeners have this advantage with long summer days.

@rigel123:
the camera you use for many of the solar images, the DMK31AU03, is a monochrome camera, so how do you get colour in some of the images - is that added during processing?

Mike

Yes, color is added in processing. I'm almost to the point of just leaving them all black and white. Taking color shots of the sun with a color CCD loses resolution so nearly everyone uses mono cameras and adds color during processing. All I do is use color balance to get a color that i like.
