FOR SALE: Lunt Double Stack Etalon for all LS60FHa Filters and LS60THa Telescopes

Post by nicosolcy » Fri Jan 22, 2021 6:53 am

For sale is my Lunt 60mm DS module in excellent condition. Comes with relevant literature and Lunt carrying case.

I decided that I want to release funds for another project and I also like my single stack images well enough to stick with single stack imaging for quite some time - and learn more about post-processing before attempting double stack imaging and processing.

The DS Module new is £2,281 and I am quite happy to let it go for £1,140 delivered – 50% of new price. Shipping will be with tracking and insured, via TNT Worldwide. I will also include the M90 rotation adapter which makes aligning the DS module a breeze and safer than unscrewing it a tiny bit (as most do).

I have in Madrid a Stelarvue sv 90, triplet fluorite in good state. They were tested one by one by Vic Maris. Are you interested and we swap?
Thanks
Joseph

Hi Joseph,

Please send me photos. I might be interested, even though I already have a Borg 90FL.

Any pictures of the sun you have taken with the DS on the scope you can share Nick?

Well, there is one but it is embarrassingly bad because my 178 displayed the dreaded double stack grid pattern, plus I was a bit out of focus, so I didn’t bother much with it. But, if you insist ;)

I just don’t want to change my 178. As a combo with single stack, I love the images and I have yet to even closely reach the potential of this setup. So, don’t want to get for example the 174 and start dabbling in double stacking.

I’ll leave that 3 years down the line when I set up (fingers crossed) my obsy and I shove a 100 Lunt in there!

Hmmm, processed it and it ain't the worse ever, but the grid pattern of the 178 is a problem (ignoring the lack of focus bit in this image).

Oh, well, If nobody is interested, I guess a 174mm would get the job done ;)

No, not necessarily. The 178mm 2.4um pixels are much better suited in terms of sampling for the native focal ratio of the Lunt, it's just the 178mm has this artifact when imaging in Ha. With a 174mm you would be under sampling which is just effectively loosing resolution and equivalent of using a smaller aperture scope.

It is a good price for the etalon though.

Seems no takers anywhere despite the price, so it will just sit there until I revisit it ;)
