The "classic" for solar imaging is the ASI174MM. It supports 1936X1216@164FPS Full well: 32ke- It is a global shutter camera. The 1600 supports "only" 1920×1680 57.7fps Full well: 20ke- It is a rolling shutter camera. But the 1600 has about twice less read noise which is a + factor. From the numbers...

Your Ha double stack is very uniform and also your SM40 and SM60+SM40 provide outstandingly fine results.

A solar wedge gives much better/contrasted view(image) than a regular front astrosolar (or any other make) filter. The solar continuum filter is passing above 800nm, at least mine. I would strongly recommend to use an IR cut or an UV/IR. The polarizing filters are also generally passing in IR. Care ...

Very interesting this idea of having the SM60 almost "inside" of the SM90. The SM90 has probably a bigger central spot than the one of the SM60. Here is my experience about stacking 2 old fashion SM60. Stupidly, the treat of the front and rear of the SM are not the same, so an adapter is needed. Tun...

Very patient job. Congrats.
I wish I could once image one.

When editing your post, there is a button "media" just above the edition field.

Thank you for the comments. Sorry, I'm not very active on the forum. Alexandra, I have seen your posts about your Coronograph. I have both the scope and the Coronograph matched together, from the same source. Once we have understood how the instrument works, it is not so difficult to adjust each fun...

Stunning of details.
Great shots.

Interesting this auto histo feature. I should give a try.
Very fine pics.

The subtel treatment keeps the very fine detail.
Well done.

Congrats!

Hi, I could visually observe trough a coronograph some years ago. I still remember the very clear and comfortable view of the protuberances. Here, one pic with a version from Baader. It is quite a strange instrument, with 2 focus and some intermediate lenses, an iris with the occulting ring(s) at th...

"Don't forget to de-aluminise the secondary mirror!"

If you do so, you will have a very strong filtering.
Maybe you want it that way, but keep in mind that you will have to collimate it!
