Re: 2020.06.09 H-a Full Disk and AR12765 closeup with C11

Am I correct guessing the F/D was F/42 at the Quark etalon?

Re: Can I have an 2020 update on where we are with Ca-K filter controls.

John, I would advice you to move ahead and not follow in the other's tale. You do have a fantastic device - the SAFIX, which can allow you to fine adjust your imaging train when it completely assembled. Do not also listen to tales that a good seeing is so rare that there is no sense to hunt for it a...

Is it time to create a special topic now, where these images can be published not being sinked in the solar images stream? May be some planetry imager...

Re: Getting rid reflected in C11 CAK imaging

Alfred, Is your primary D-ERF tilted at all? If not, I would add a small 1 degree tilt to it via rubber gasket under 1/2 of the filter inside the holding cell. It should handle your reflection. I too am curious about the innards of a Lunt module in terms of what is in front of the actual narrowband...

Re: June 13: H alpha and CaK

Hi Peter,

Very nice session. The CaK is especially good. Looks like the best seeing in this session was when you imaged in the CaK.

Re: June 2nd 2020 ARs + Prom

Hi Phil,

Thanks for sharing these images with us. They are excellent.

It seems that the best results may be achieved with a reducer of smaller reducing power.

Re: Prominence on the northwest edge today.

Excellent resolution, nicely captured and perfectly colored prominence, Jozef.

The only question - what the telescope and accessories were used?
