Testing the new setup for the first time. SCT Celestron C8 f / 20 with solar leaf Baader plus sunscreen continuum. Before, I used a 120mm f / 6.9 acro refractor. It was a big change of aperture and focal length.
Many details on the sunspots but what pleased me most was that for the first time I captured the convection cells quite clearly.

Looking sharp Avani, well done.

Very well detailed 'spots' you've got there, Avani!

Carry on,

Cracking image Avani.

[David Smith]

Superb

[DrRobin]

Wow, that is one great shot, well caught.

Lovely detail captured Avani.

[Pete Presland]

Some really pleasing detail visible there Avani, especially in the Penumbra. Like you said the convection cells quite clearly visible.

Very nice indeed. A lot of detail captured. I find it is not always easy to combine the solar film and solar continuum filters in my C8, I sometimes get internal reflections, unless I carefully tilt the solar film filter, especially when using a PowerMate or TeleXtender. Did you need to tilt the solar film?

 To be honest I did not worry about that Michel! It was the first time I used this solar setup, before using a 120mm refractor.
I did not notice any internal reflection and as you saw I used PM 2X as well.
I have been studying a lot about solar and what I have done that I did not mention there and that I use a Luminance filter combined with the Solar Continuum. I learned that Baader's solar continuum shows a certain leak in the IR that degenerates the photos. So using a Luminance filter that is also a UV-IR block helps to solve the problem.

I also used a luminance filter, and the extra flat surfaces can create extra problems. Anyway, the last time I sorted it by a slight tilt of the film, so it is solvable.

Fantastic first results there Avani. As you say that's quite a step up in resolution & it clearly shows.

I have been thinking of betting a suitable ERF for my SCT but making it usable with the 152mm frac by using a 'reducer ring' of sorts, images like these from the SCT make me want to save harder ;-)

Well done.

Granulation looks great! Nice captures

[Ruud]

Wonderful new ventures -- wishing you sunny days!

[astroavani]

Thanks Ruud,Ewan and Tyson!

Ewan, using an ERF is an interesting solution if you already own an SCT, they perform very well on lots. Another option is to use a Baader solar sheet but everything will depend on what you want to do.
