March 22nd Images

Post by MapleRidge » Tue Mar 24, 2020 1:48 am

Good day everyone...

I had a clear, cool day yesterday and time to work at the scope for several hours starting late in the morning. I found several oversights in the setup of the new mount/scope assembly, mainly cable issues which I think are now resolved. The one remaining problem is that I wasn't seeing any life in the SSM module when I hooked it up, so I need to check it out more.

The advantage I had Sunday was I had time to image in WL and CaK as well as Ha. The first images were in WL and CaK taken through the iStar mm, f8 scope and the ZWO1600MM camera. The WL image was taken through a Lunt solar wedge fitted with a Baader Continuum filter:

A modified Lunt Wedge/B1800CaK module with a Baader K-Line filter mounted in the camera nose piece was used for the CaK image, with the scope stopped down to 115mm:

Full disk Ha images were taken with the Lunt LS80T/B1800Ha solar scope and ZWO174MM camera. Both are full disk composites of separate disk and limb images with the limb inverted. Overall the disk is pretty blank, with a faint filament in the south, but numerous proms. The first image is in single stack mode, the second has the DSII module installed. I am not happy with the tuning in this image, but this was the best of the DS images:

For higher resolution images I moved the DSII module to the CR-150 OTA (150mm, f8), with a 3x tele-extender ahead of the 174MM camera. The first images are some of the few areas showing activity on the disk:

The image below covers the same area as the last, but with the pressure tuner set to 0 PSI which acts like a deep red filter...and it brings up some of the granulation:

The real show of the day were the proms...not massive structures, but many of them had fine details:

Nice set of images there, Brian.

Always makes me chuckle when I see you mention "a cool day", knowing that would be something completely different by my standards :D

I was thinking exactly the same as Jochen above :lol:

This is a very fine set Brian, great to see you imaging in the other lights and lovely to see the polar regions too, but my favourites today are the prominences :bow :hamster:

You had a very productive session, Brian. You were able to resolve very well those faint prominences, that has been so difficult to do for many of us. A very well deserved SPOD !
