Top shot Stu! The skies were very milky for me too.

They're excellent disks Phil! Hoping to get a few images myself this morning if the weather holds...

Thanks Pedro, thanks Brian, thanks Phil. That's what I found too Phil, the movement is subtle but there's quite a bit of it.

You've got a very comprehensive collection Pedro!

These are great images Peter! I'm assuming the C4 is not front filtered at all - do you have no thermal issues with it?

Always like looking at your images Peter. Glad you're on the road to recovery after your scare.

Great images Marty! Glad the sun has returned for you.

You've done a great job there Marty, nice engineering solution.

Nice disk Brian!

Having a look online it seems all Lunt etalons are stickered as double stack certified.

If, you can, try before you buy Maurits!

That is an excellent image there Phil! Assuming you used a DERF up front?

Great shot for the conditions Alfred. Lou asked exactly the question I was thinking of there...

That's great Bart, I love the detail in the spicules.

Thank you!

Nice collection of images Eric!

Looking forward to the findings Ken

Yes, ditch the welding filter. Use and UV/IR filter in the first instance, you could always add a green filter to increase contrast.

Lots of nice cinema there Pedro

I'm using Firecapture...

Thanks everyone! Jack, I use a Hinode solar guider to help things during capture, and, a SSM to trigger capture based on seeing. It's a very automated system, and while it runs away I can go off an make a coffee, read the newspaper etc. I then use ImPPG to align (before sharpening) on the solar radi...

Thanks guys!

Heya Chaps! Sorry Maurits, i've had this flagged to reply for a while. I have both etalons, the red one and the white one. You've noticed all the physical differences M80 v M90 thread size. The red one has a hinge tuner, same as the coronado SMxx etalons, the white one the etalon is tilted within th...
