Very nice Dave , your getting better fast with that new equip.

Definitely getting better. Nice capture, Dave!

Thanks guys

it's becoming an obsession haha

been watching a few videos on Photoshop image processing to bring out the best in the captured details

Keep going, it is an addiction, can't believe i changed my mind so fast in this year and i am just starting out, first i said i want only DSO, then i added planetary, and now i want to do solar imaging too, too much things i want to do regarding astronomy.

Is it possible to take good solar photos in the hydrogen-alfa spectrum using a DSLR with the proper filter? If so what is the specific filter? The companies that produce the HA filters seem to be for dedicated camera/lens/telescope systems for solar photography. I haven't found any screw on filters in 77mm (for the Canon 100-400m), or any filter for the Canon 600mm f/4 (which doesn't accept screw-on but rather a drop-in). A dedicated solar telescope for isn't an option.

Yes you can

I have also purchased a Daystar Camera Quark filter they have adaptors for either Canon EOS or Nikon
and just click in between your camera and telephoto lens

https://www.bhphotovid​eo.com …uark_eyepiece_f​ilter.html

They are available as a Prominence filter approx. 0.65 - 0.75 A or Chromosphere approx. 0.45 - 0.55 A

they also come with an eyepiece adaptor, so instead of your camera on the end, you can put your eyepiece there


EDIT .... just reread your post, there are no simple screw-on filters. Ha solar filters are very specialised and require a lot more technology
than just a piece of filter glass over the front of your lens .... this is why they are expensive
