Narrowband

Recommended Posts

Browsing through a monthly astro mag in my reading shop (Smiths),I noticed mention of 25 Canum Venaticorum.

It struck a bell as I'd managed a peanut, until the other night using a 5.5mm Meade UWA in the 150 C6r to get a very pleasing split at x218. The split is 1.8, but there's some difference in magnitudes , as you will observe.

Easier and most pleasant were,

2 CNv

Cor Caroli

Σ261

I've always been very fond of this area, it's packed with galaxies , if you have the eyes and the skies,

Nick.

As the seeing was good to excellent this evening, I had another look with my 127mm Mak at 25 CVn.

At x250, the two are split although the fainter star sits on a diffraction ring. Colours? Lemon primary, slightly cyan secondary?

I managed to split 25 CVn with my ED120 at 256x and 300x despite murky skies this evening. Thats a 1st for me as far as I recall so thanks for the "heads up" Nick :smiley:

I won't try and work out colours in these murky conditions but the brightness difference is quite substantial.

I also took a look Cor Caroli and Alkaurops as well with nice results.

Thank goodness for these lovely doubles, it would have been a useless night for astronomy otherwise :smiley:
