Re: Ha Quantum filter PE 0.4Å

It only drifts off on the HaT, after several hours Valery, and that has only been this summer when ambient temperatures have been 25c+ outside whilst imaging.

Re: Ha Quantum filter PE 0.4Å

About temperature that is the next problem. I saw yesterday that in my area it is taking long time to cool down or nearly it does not cool down. I think I will have to add some fans to cool it down. Yesterday the Quantum remained for a very long time at 6563.0Å and the light was yellow. I had it ad...

These are all way cool shots Derek! Does the timing of the satellite correspond with the launch of the Parker probe?

Re: What is a blocking filter function?

The only way you could do it is with a camera Quark from Daystar, but even then I don't recommend a DSLR for solar imaging.

AR12717 is what is designated here as AR12713 http://spaceweather.com/archive.php?view=1&day=21&month=06&year=2018 The sunspot na...

Top shots Marty! The last ones are off band and it is just continuum leakage coming through, hence why you can see the granules. The sun looks pretty much overhead where you are.
