Hi,
They are graphs of the observations of any 2018.
It seems that Omi Cet is at its maximum, surprises its emission in the Hgamma and Hdelta.
As for the SU Lyn, it shows its magnificent sawtooth and its unique Hapha.
Regards, Joan.

Hola Joan! Wonderful 2018 spectra...
Very interesting the Omi Cet evolution. I saw a similar state in your old spectrum taken on February 9, 2017 (from ARAS db).

I still can't observe in this year...

All the best!
Paolo

Buongiorno, Paolo,

Now the Omi Cet is close to its maximum and this must be the reason why Hydrogen shows this amazing activity in the violet.

I usually follow the waether in L'Aquila and the winter that you have is really a bit extreme.

Umberto told me that you also have serious problems with dullness in the telescope's plate, in cases of very intense moisture, the heating strings in the commerce are somewhat precarious. I also have these problems in Sta. Maria.

Here, http://www.elementoscalefactores.com/pr ... -volts.htm, I bought the reference, RFSS45 / 3/12, (minimum three units, total price € 37.70), I think it will be enough to solve the problem.

I'll know for sure the next week.

Un forte abbraccio, Joan.

Gràcies Joan!
Luckily we have few nights with high moisture content. I use an one meter long Kendrick velcro heather with an old microcontroller. It should be reliable enough (no problem up to now).
