Sol in H⍺- 11 August 2021

[Hughsie]

Below are a selection of images taken with the set up detailed below. I recently acquired a 4x Tele Vue Powermate which has reduced the focal ratio of my Lunt 60mm combined with the ZWO ASI174mm down to a level more manageable, whereas with the 5x Powermate there was significant over-sampling.

Here we go....

 

Image 1 - An overview of the solar disc revealing AR12853 which I focused my attention on today and a nice prom on the South East limb.

 

Image 2 - Moving to the South East of the disc we have a nice prominence but little in the way of detail on the Chromosphere. Captured with the 4x Powermate.

 

Image 3 - Inverted image of AR12853. No spots on show but this area has been showing a lot of flare activity. A nice filament near the ‘dark’ flare areas and a few smaller filaments to the South.

 

Image 4 - Just for a different perspective I have included an inverted image of the same region in Image 3, both captured with the 4x Powermate.

 

Image 5 - A wider view of the last two images showing the position of AR12853 on the solar disc.

 

Image 6 - Image 5 now inverted to reveal the prominences on the solar limb.

 

Equipment:

• Lunt 60mm TH⍺/B1200CPT
• ZWO ASI174mm & Tilt Adapter
• SkyWatcher EQ6R-Pro
• Tele Vue 4x Powermate
• Images acquired with SharpCap Pro.
• Stacked using Autostakkert 3, inverted with ImPPG and remaining processing done through PixInsight.

 

Cheers

John
