11 Sep HA images with a C11 and Borg 76 from Singapore (latest added 14 Sep)

Post by yltansg »

We had lots of rain recently and more rain is expected in the next 2 months. Today (11 Sep 21), I finally caught some sun :D

Photographed sunspots AR2866 and AR2868 with a 11" SCT fitted with ARIES D-ERF and a H-Alpha Daystar Quark chromosphere.

Image

Weather has been atrocious and I was glad to have caught something.

Make a right click to see the image in its full resolution.

Cheers.

Alfred

12 Sep 21. We have tons of clouds and some windows for imaging. Today, I did some full disk HA images. The gigantic proms is holding well.

The image was taken with a Borg 76mm refractor fitted with DS Solarscope SF50 etalons.

Enjoy!

Very impressive images Alfred
That prom was amazing all I got was a ten minuet view through clouds but stunning.

Like Alessandro I had a little play as your images are so good, I put both full disks together then colorized it, just such a wonderful image.

Lets hope for more of this in this solar cycle.

Cheers Rod

Dear Rod,

Thank you very much for your feedback and improving the image. Could you post your colorised image?

Thanks.

Hi Alfred

With pleasure
Although I prefer grayscale images, I can see more detail in them, I am practicing colourising as others prefer colourised images.
I did this with your image because it is so full of data that I cannot get at the moment because of bad weather.
Fantastic Borg setup.

Cheers Rod

Dear Rod,

I like the colourised image. Thanks. I prefer grayscale images for the same reason. The Borg 76 with DS SF50 is my workhorse for full disk imaging.

Hi Alfred,
That's a great prom capture and I now understand that it did produce a CME, so well done.

A superb Ha disk, Alfred. Congratulations on the very well deserved SPOD ! That image should be in a science publication.

From the same batch of photos captured on 11 Sep:

a closer look at AR2866

Image

AR2868:
Image

This C11 setup is capable of better images. I am happy to have these, given the weather condition.

For good measure, I also used a ASI174MC to capture this full disk, just to see the shade of red from a colour CMOS camera.
Image
Compared to the ASI174MM camera, the loss in resolution is quite obvious.

Enjoy.

Alfred
