Sundays Ha Offerings - 19th June
Saturday was a washout, woke up to rain, went to bed to rain, and it rained at all points in between. Looking at the weather for Sunday and there was a brief window first thing with sunny spells forecast. I woke at 6.30am to light coming around the curtain, which is always a decent start, and while at that time it was indeed overcast there were a few breaks about and a blue gap heading my way. I was out about 7.30am, armed with coffee and turned my attentions to a full disk. Visually it looked really nice and I knew I had to take my eye away of I wanted to get any images in before my 'window' closed.

Ha-FD-DS50-2x-cemax-zwo183mm-2xbinning-colour by Mark Townley, on Flickr
The above disk was taken with the double stack Lunt 50 setup on the 60mm f6 scope, 2x cemax barlow (it runs about 2.25x with the camera) and the ZWO183mm with 2x binning. I'm experimenting with the camera recording in 12bit, and have to say in this mode it seems to take ages for the histogram to max out. I had the gain running on 50 which should give me about 12 bits of dynamic range - as the gain is increased the effective dynamic range decreases. I'm quite liking using the camera in this way, but there are more experiments to do before I settle.
I only had time to capture 3 recordings before the clouds closed in again so started to process them. Looking at the live satellite feed I could see that I had another blue gap heading my way, and while it looked good, experience tells me that by about 8.30-9.00am in these conditions the instability would set in and a 'new layer' of cloud would form. I decided to get the Coronado DS90 out, as feel have been neglecting it of late, and using the nosepeice of the 2x cemax on the ZWO290mm (gives a bit less than 2x) I decided to go fishing the cracks for a solar catch. Seeing was all over the place and there was a 'range' on the focuser that worked rather than just one spot, so, record lots of frames and hope for the best.
AR13030 was looking very dramatic and dynamic and with clear skies would be a great subject for an animation.

A couple of smaller active regions were crackling away:

By now I was fighting and imaging through the scudding clouds, but I couldn't resist the proms!

I would have liked more time to explore visually with the DS90 but the clouds were in for the day at this point. I'm really pleased with the haul as the weather forecast initially for today was not good at all. My clear sky window might have been brief but I managed to use it well!
Hope you like these, I'm hoping to observe first thing in the morning before I got to work.

Excellent images, Mark. Your FDs are so perfectly illuminated and show beautiful detail. The other closeups are great too.

Re: Sundays Ha Offerings - 19th June
Mark,
What a beautiful set of images. I don't think they have missed a single detail. I especially love your closeups of the AR13030-32.33 active region complex.
Two thumbs up!!
James
P.S. It's time for a beer!
