High Resolution H-Alpha Solar Image

[yltansg]

Hi,

It has been a while since I last posted an image of the Sun. I have made further progress on high-resolution solar imaging in H-Alpha, CAK, WL, G-Band wavelength. An example of H-Alpha imaging is shown below:

Setup - 8" 3-Band (H-Alpha, CAK and G-Band) full aperture Dielectric Energy Rejection Filter and a Celestron C8.



Looking at Sunspot AR12741 on 14 May 19:


You can do a right click to open this image in a new tab and will be able to see the image at full resolution.

Wow! Plenty of details of solar filaments.

Great Image

Thanks Kochu and CheeYiun.

It took me some time to experiment and find this optical train that produces a satisfactory image with my Celestron C8 SCT. I will next work on this C11 and see if I can get higher resolution images. Cheers.

Incredible detail! These must be some of the highest resolution solar images around

Thanks Ivan. After some tinkering, I am now able to produce this quality consistently. For high resloution imaging good seeing condition is essential. Good news is our local seeing condition is good. Next I am trying the next higher resolution with a C11 SCT.

Wow! The hi-res image from the 8” SCT is breathtaking! Couldn’t wait to see the next one on the C11.

18 Aug 19. Peering into the solar upper chromosphere in H-Alpha using a Celestron C11 SCT fitted with a full-aperture D-ERF. Despite being spotless, the Sun has many interesting 3-D wavy plasma features near its southern limbs. Seeing condition was poor. The Sun was covered with passing clouds throughout the imaging session.



The C11 solar scope setup:

Can expect better images from this setup.

Nice Solar image..!
