Re: New Sunspots! CaK Sun 2nd March
Thanks James, just a stacking artifact i'm afraid, nothing exciting. I wanted to capture, process and get these images up quick, so they've had the rough and ready treatment.

New Sunspots! CaK Sun 2nd March
The skies cleared here late this afternoon, and when to my surprise I looked on the AIA imagery I saw a couple of active regions had formed. I raced home from work to try and catch the last rays of the sun. I did, but the sun was so low and dim I had to use 2x2 binning to even be able to expose. Sti...

Sunday Sunshine - 28th February
For the 3rd day in a row (must be a record!) the day dawned sunny and clear, and I was keen to observe. Starting at around 9am with the 120mm scope at f28 for Ha, and again found myself fighting the seeing which was deteriorating by the minute. First off our departing active region and a bit of aggr...

Re: halpha sun of March 1st
Very nice images Stephane! I don't know if you're aware but you can't view them in the forum - have to right click and open in a new tab. This is because Astrosurf is a non secure web host - http not https.

Re: Sweet spot, banding and tilted etalons ...where are the limits ?
Hi Marty, My mindset went this way a few years ago, yes, use the larger etalons to increase the sweet spot, the problem you will have is finding commercially available collimating lenses, hence JAPP producing his own 80/-800 lens. I went the route of using my good Lunt50mm etalon on a 60mm/f6 frac w...
