Active Regions from 6-4-24

During this quick observing and testing session from a few weeks ago, surface features were quite apparent. An Active Region is concentration magnetic activity that has several types of features within the area. In this region, numerous sunspots (dark spots) are concentrated in three areas. Plages, bright yellow areas near the spots associated with high heating, are also visible. Lastly, Active Region Filaments (ARF), long dark fibrous strands populate the left and central active regions.

PS: This was the last of the older solar images, I only have one more and that is only five days old...

Solar Surface & Proms from 6-1-24

This is a long delayed image from three weeks ago of the sun (there were two but this was the best) - been busy with the end of the semester and such. I eventually would like to do more animations but that takes a lot of time and I need more general practice. I like how the prominences turned out as well as the surface detail especially around the active region with the sunspots. I especially like how the two main prominences are actually connected to each other as shown in the image. 

Unfortunately I don't know the designations since they were collected a few weeks ago. If you go on the solar websites that I know it is straightforward to get the designations, however, it is not so easy. I like processing these images but it is much different than processing deep sky stuff. The next purchase would be an autofocuser however the reason I haven't purchased it yet is that I use this scope for visual solar and I find using the manual focus knob much easier than anything else for visual purposes. On the other hand, all you really need to do is unscrew two allen wrench push pin screws (for a ZWO EAF) and you can make it manual so I think that is next.

Messier 99 (2024)

This is my latest version of Messier 99 (M99), my only other version of this is from 2017 taken with my Canon T3i/600d attached to the ED80. M99, also known as NGC 4254 or St. Catherine's Wheel, is a spiral galaxy located 40 million light years away in the constellation of Coma Berenices. It is approximately 40 million light-years away and 75,000 ly in diameter. Numerous other galaxies much further away than M99 are also present in this image.

Although the galaxy looks to be face-on, it is actually inclined 42° from our line of sight. Another interesting item is that one arm is more tightly wound than the other and the core seems to be slightly offset from the center. Interactions with other galaxies are the likely cause of the peculiar shape. The galaxy is not classified as a starburst galaxy, however, studies indicate that it has star formation 3x larger than other similar galaxies. As evidence many blue star clusters make up the arms and give it a blue tint. Note: Hydrogen nebular regions which would normally appear red are also found in the arms but unfortunately I was unable to bring them out - I did collect some Ha data which would have helped but it did not look good due to bad sky conditions or camera ice so I did not use it.

Solar Animation from 5-26-24

This is the final run from my April 26 imaging session with the ZWO ASI174. I decided to do an animation/time-lapse to finish off for the day. I collected several 500 frame bursts every 30s for 27 minutes to make this time lapse. I really like these solar animations as they show how dynamic the sun really is. It is certainly not the best time lapse as it is overly above the chromosphere and there are still some blurry frames (although I did remove several). I could go on with critiquing it but I learned quite a bit by doing it. For one thing I did a lot of Batch Processing work using many different programs. The process I used was from the Youtube channels of Chuck's Astro (https://www.youtube.com/watch?v=VXijbjkclMc&t=647s) and AZAstroguy (https://www.youtube.com/watch?v=-L4yHtkpVY4&t=11s).

Basically it was Sharpcap (capturing), AutoStakkert (stacking), PixInsight (crop), IMPPG (sharpen, align), Photoshop (color, time/lapse), Topaz DeNoise (sharpen), and I attempted to use NAFE. I don't know if I could have improved it as so much depends on the seeing conditions and by the time I did this, the conditions were deteriorating.

In addition to the flares on the end, the surface shows quite a bit of neat activity as well.

Surface Features from 5-26-24

In my ongoing journey to the sun, this image focuses on some of the surface details of the chromosphere. Numerous sunspots (3691, 3695, 3690, 3693, & 3692) and filaments are visible. A fairly active region located on the left side contains multiple sunspots including 3691 and 3695. On the right hand side a long narrow dark brown linear structure known as a filament seems to point towards a smaller active region that includes the sunspot 3692.

This was captured last week at roughly the same time as the flares from my previous post. Similar processing was in order to bring out the surface detail and this was a bit easier since there were no flares to bring out.
