CaK Sun 8th October

Post by marktownley »

Fair but distinctly cloudy weather came to visit at the weekend, the sun is starting to get really quite low now and so you just have to image when you can. For a change the seeing was quite reasonable too.

I started off with a CaK full disk, this time 60mm f17 with the 100mm Tal refractor stopped down. You get an idea of skies here:

Despite the highest spatial resolution, the image is actually quite soft because of the higher spectral resolution of the filter running all the way at f17, camera was the trusty old PGR ICX814. This is looking higher in the chromosphere, rather than poor seeing.

Next up and a swap of scope to the bresser 127/1200 stopped down to f15 with the zwo290mm for some close views:

You can see the haze but also how the neighbours trees are getting close to hindering views...

Think it was the haze throwing me here, but the close images are not on band, somewhere in the blue, and as a result don't have the contrast I know the system can give. This is an exercise in clocking the filter with respect to the OTA, probably next year now being realistic. Still, happy with how they turned out!

Very nice Mark. Old school manual focusing? I'll pretend I'm not envious.
Same hazy milky skies here in Kent for weeks now.
I tried imaging the same day ("easy" O3) but never seen the image jump around so much with hardly a butterflys waft at ground level.

I do like :-)

Late to the solar party - April 2023. Missed 5 cycles. Much to learn. Much to spend.

Boxed for 15 years - Zenithstar 80, Skywatcher 150 f8, Celestron C9.25.
Now all have seen the Sun and demand I spend further, without regret.

Nice CaK imagery, Mark. Nice refractor too!

And the trees are starting to hinder my views too, driving me to the side of the house to set up. No observing at all today. Too busy and mostly cloudy.

Summer always goes by so quickly and the autumn sun is no longer ideal. It's a very nice set of photos, Mark.


I do not look at the sky with the eyes of an astronomer, but of a person looking for the beauty of nature.

Very nice, Mark. You’re lucky to have had any chance of imagining at any wavelength. Just clouds and more clouds here with rain showers too :roll: :roll:
