My "Luntonado"

[Peter Drew]

My main solar telescope is in its own observatory at the Astronomy Centre a couple of miles away so not always convenient to use.  At home I usually have a PST for a quick peep to see if further effort is warranted.  I also have a Lunt35 purchased mainly to see what it was like.  Both scopes are quite good but nothing special.  Recently, on a whim, I attached the stand alone Lunt etalon assembly to the front of the PST to check if there was any compatibility.  The results have been remarkable!, jet black filaments contrasting with bright plages and prominences, tuning just the PST reveals everchanging details.  This is now my favourite g & g telescope.  I don't have  any solar images from it as I'm purely visual but the views are very similar to the GONG colour images.   🙂

Looks like one of the easiest and best astro modifications to do, ever.
