Sun in CaK 17th Sept.

Post by Carbon60 » Sun Sep 17, 2017 7:10 pm

Hi All,

All of my Ha images from today ended up in the bin. I just couldn't obtain anything worth posting. My mosaics were patchy with changing seeing and thin clouds during a late afternoon session. What did survive was a CaK FD which I've produced here in mono and colour.

Lunt B600 module on a 72mm f6 refractor, with a Basler acA1920-155um camera and 2.5x Powermate. 2 pane mosaic.
AS2!, ImPPG, PixInsight.

Thanks for looking.

This turned out well Stu.No that feeling though.Mark T is onto the right thing with smaller apertures with bad seeing.

Well, these full discs are first class :bow :hamster:
I did all my chores on Saturday as the weather forecast was supposed to be sunny all day on Sunday. I sat and waited, it was cloudy and then it started to rain. It rained all day! weathermen lie. However while waiting I processed all my eclipse shots so at least the day wasn't wasted. I am now seriously suffering from solar withdrawal now ;)

Hi Stu: that is an excellent disk ! I was out yesterday but the seeing was horrible and nothing worth posting came out. The images showed not detail, were noisy, almost frying...

I am glad you had at least something to show for.

Good stuff Stu.
I had very much the same experience yesterday with Ha being very difficult and CaK not much better!
The Tal 100mm f10 has pretty much become my 'grab and hope' scope in these times of dire seeing. When combined with the Quark, it seems to cope with poor seeing far better than my Lunt 100 Ha and is pretty close to perfect for CaK whatever the seeing throws at me.
In very good conditions I add a x2 or x2.5 Barlow/Powermate and get stunning detail. In average conditions I just use the Grasshopper camera alone or add a x1.6 Barlow. In really poor conditions (like yesterday) I will step it down to 80 or 60mm and hope!

Many thanks everyone. It seems we're all struggling one way or another with poor seeing, or clouds, or both. Let's hope for better conditions soon.

Fine images, sharp and very well processed.

Are you able to see something through your Ca-K module visually ?
