Re: First real CaK prom!

Superb......... I was smiling for hours after capturing my first CaK prom and it must feel even better with a DIY system.

Re: CaK with 250 mm RCT- REWORKED!

Great images Stu and overall very interesting stuff. I can use my 100mm f10 Tal most days for CaK and with two x2 Barlows stacked together I have had very sharp results on days of really good seeing. I have tried using the CaK1200 unit on my 152mm f5.9 scope with promising results - I have a near fu...

Frustration in the Sun

Woke up to blue sky which turned into cloud precisely 5 minutes after the Sun cleared the big tree in the South East corner of my garden :evil: :roll: :evil: Very interesting structure in upper left quadrant........ only visible in Ha. Only managed one half decent capture before I was fishing in eve...

Re: Ha Chromosphere 250 mm RCT in poor conditions

Pretty good image Stu - that area looked very interesting for a few minutes. I had exactly the same experience this morning with blue sky until 5 minutes after the Sun cleared the big tree in my garden!

Re: August 23 2020 Observations

About as blank as I have ever seen the Sun but your excellent observations support what I often tell my friends; there is always something to see in Ha if you have a reasonable aperture and the patience to look!
Thanks for sharing your experiences.

Re: Sol from the 22nd of August 2020.

Good use of a 'blank disc' day Eric!
As others have said, number 4 looks very good indeed and I look forward to seeing your next post with a bit more action on the surface.

Re: August 22 FD CaK H-alpha AR12772

Impressive set of images Leo. The Lunt CaK unit is a great bit of kit and I'm sure you will be blown away once you use it on a disc with more features. My unit is the CaK1200 and I use it with a Tal 100mm f10 most of the time. In poor seeing I step it down to 80mm or even 60mm but on good days I use...

Re: A few from today 20th Aug '20

Nice set of captures Stu. I was out fishing in the cracks between the clouds and looking for some reasonable seeing this morning too. As you say, take what you can after a week of cloud and gales forecast for tomorrow!

Re: Prom measure on scale

Hi Maurits As its my image you posted......... I can tell you exactly how it was done. The scale Alexandra explained is what I used but it can be a bit frustrating as the numbered lines outside the disc are often in the wrong place. I edited the original overlay so that there are numbered layers at ...

Re: Experimenting with new camera

Thanks guys :bow2 The ASI290MM has been a pleasant surprise. When I ordered it I didn't give a thought to whether it would work for Solar imaging as I was intending to use it for deep sky and/or AllSky work. However, having realised that it has incredibly low noise (less than 1.5 (e-rms) above 100 g...
