[Rusted]

Hi,

I have just added a Lunt 1.25" Herschel Prism to my old Vixen 90mm f/11 for my first, serious, white light images.
Solar pores on surface at 1000mm x2 TS GPC + 2x Orion Shorty Barlow + Baader Solar Continuum.
V. Pleased with image quality so far but need more amplification! What is the smart money using?

A certain gentleman is experimenting with Gigapixel AI...

 

But what you've teased  out - especially the first one - is wonderful. With your 174?

Yes, thanks, this is the '174.
I was amazed at the detail given the stack of Barlows picked straight from the drawer.
It it windy too. So the scopes are moving about more than I like.
Is there a 5x Barlow in my stars or another camera better suited to 1000mm f/l?

I think your small 90mm aperture is going to be your biggest issue rather than Barlows or cams.

[Rusted]

Thanks Freddie. I can just as easily use the 150mm 6" f/10 iStar. I'll give that a go.

Just a matter of exchanging the PST etalon + filter stack for empty extension tubes.

I have used the iStar for lunar without removing the D-ERF and protective UV/IR filters.

The seeing may have gone off but the 150/1500 produced very inferior surface detail with the Lunt prism compared to the 90mm.

The first image is with no D-ERF. The second image is with the D-ERF in place.

Yes, you will need decent seeing to take advantage of the larger aperture but when the seeing is up to it, you will see a very worthwhile improvement.

That has come out fairly well. I would like to capture some granulation myself, when i get a chance. 

I have been thinking of getting a filter for my C9.25, but the chances of using it in decent seeing seem few and far between. Not sure i would gain much from my 120mm refractor.
