Re: Active coolers for sun cameras Apollo and Saturn

They occurred. Two of my friends literally baked their cameras on the AR150/F6 in July with just the D-ERF and Quark combo.

Etalons Lunt LS80T-Ha and DSII - focal length

Focal length of the collimation and correction lens for the Lunt LS80T-Ha and DSII standard.
Does anyone know the focal values of these lenses?

Re: Active coolers for sun cameras Apollo and Saturn

I don't think this cooler brings a noticeable reduction in noise, but it safely protects the chip from high temperatures in the hot summer months.

Re: Todays shots between clouds 02.10.

Seeing was so bad that it was impossible to focus. I had to focus by guesswork and trash 4/5 of the sequences.

Re: Autoguiding on the sun

The guidance principle is probably much more primitive in Firecapture than in Lusol.

Re: Test new Quark combo with TV4x PMT and Saturn IMX533

You're welcome.
I use the TV4X PMT because it has the same thread on the output as the classic Quark, and I use a transition to 1.25" for the combo.

PMT = Powermate. PMT is telecentric element.

Re: Solar harvest 24th September 2022

TZ4 is designed for F7-F8. If you have a telescope with a different aperture, then the TZ4 does not work properly and neither does the etalon. What is the brightness of the OTA?
