The only drawback of the TOA 150 is its the price and ... its aperture. I wish I have a TOA 200 ;-)

Thanks Bart, I thought that might be the case.

Brilliant!

Well said Apollo.

That was my thought too Pedro, I quite fancy the idea of something for quick grab and go full disks that I can just carry the scope and mount out in one go (in between the clouds!) - be interesting how you get on Pedro. You don't have clouds where you are very often so give it a try covering the sen...

Interesting comparison Raf. I did something similar several years ago with CaK. I get some reasonable images with my ED80 at higher magnifications I find, once I'm upto about f15-f25. Frederics website has some great measurements of spherochromatism https://airylab.com/astronomy-test-reports/ Regard...

Looking good Franco! Another cloudy weekend for me.

I want to try a few ideas with my skybender, these recent threads have been giving me some ideas

I wonder if it will stop tracking when the sun goes behind a cloud?

Good results!

I think I will be buying one very soon too.

Good shots Raf!

Good scope there Pedro!

Thanks Apollo, don't you go skipping off now, things are just starting to get interesting...

Brilliant Valery! Can you describe the processing technique you use on the stacked image please?

Fascinating high brow solar science here Peter, i'm most impressed! This really does from an empirical way what we might realistically expect from our CaK devices.

Those dark structures are interesting though, i've regularly seen them too.

Very nice Peter. That 115mm Stellarvue seems a great performer at CaK wavelengths.

Very interesting results Peter!

Good data Stu!

That's a beauty Valery. When you start trying that SSM it will be very interesting to see what values it comes back with.

Very good bob and apollo, glad this is working out!

Good results Apollo!

Super scope! Good luck with the sale!

Would love to see the results you are getting. I'm using a tilted 387/10 filter in my CaK system.

Great results Robert! Raining down here today so glad you've got better conditions.
