Sunday Sunshine 17th March

Another brief session on Sunday morning, it started out wet, with a brighter afternoon but I was out then for a family event that there was no getting out of, so, the sun was a quick grab in the middle in conditions like this was all I got, https://live.staticflickr.com/65535/53597268629_c3694cc170_...

Re: Early Saturday Calcium 16th March

Well that’s a revelation! In summer with a clear sky and no jet stream collecting data for a timelapse animation is my favourite thing to do. As we know, as the sun rises early morning it gets brighter so I have been sitting and manually knocking the gain back until it settles. This means I can set...

Thanks everyone for the kind comments! Auto gain?! That would be a help for early morning time lapse recordings in summer. How do you activate it? Nic, you can find autogain by clicking 'more' on the control tab in FC. I normally go 92% for CaK and Ha, slightly less for WL https://live.staticflickr....

Could you please explain why on-band CaK results in soft images? Hi Kevin. Maybe I should have widened the statement to say 'with double (or triple) stacked CaK filters in long focal ratio beams' - This is because you are reducing the amount of out of band contiunnum or parasitic leakage either sid...

I knew I had to be setup ready for the moment the sun cleared the local urban horizion so was stood waiting with a coffee. Ideally I wanted to have more time to experiment with critically ...

Thanks for the update James, a quiet sun! Clear skies here this morning at dawn (thanks to the alarm cat for waking me early!), cloud is coming in fast though looking at the satellite image, will be a race to image before things cloud out. Happy Saturday!

Just playing devils advocate here - how do you know this is giving you a 2x magnification in the system? Have you measured it or just taking what it says on the box?
