Seeing (FWHM): 1.0" for L, 2.0" for RGB
   

Remarks:

After an early end of the 2011 session at Skinakas (due to bad weather), Rainer provided us with the RGB frames for the image, which he did "by accident" (not kidding!) three weeks after the L image from Melle.

In the inverted version (see below) some filaments of the SNR CTA 1 can be seen at the lower edge and the upper left corner.

   

Bemerkungen:

Nachdem auf Skinakas die Saison 2011 recht früh dem Wetter zum Opfer fiel, konnte Rainer mit den Farbframes für die Aufnahme aushelfen, die er zufällig (ohne Scherz) knapp einen Monat später aus Melle fotografiert hat.

In der invertierten Version (siehe unten) sind unten und oben in der Ecke links Filamente des SNR CTA 1 zu erkennen.
