The Sun – 21st March 2025 by Jim Burchell

NEVER LOOK AT THE SUN DIRECTLY. Please click here for solar observing safely.
 
Another great image of our Sun taken by member Jim Burchell on the 21st March 2025. Underneath is an image Jim took on the 16th March 2025; you can see how the sunspots have moved across the Sun since the 16th.
 
 
 
 
Both images were taken with an Pentax KP body attached to 102mm F11 Altair Astro refractor fitted with a solar filter and then coloured in Snapseed.

An Active Sun – 16th March 2025 by Jim Burchell

Two superb images of the Sun today taken by member Jim Burchell.  As you can see the Sun is very active with lots of sunspots.

Jim's 1st image below, a single shot; was taken using a 102 MM refactor with a Pentax KP body attached set at F11, 320 sec and iso 100 plus a solar filter.

 

Jim's 2nd image, which is just a single shot; was taken using a SeeStar S50 smartscope.

 

Below is an image taken from Spaceweather.com showing all the sunspots with their labels.  As you can see there are lots!!!!!

Soul Nebula (IC1848) by Kevin Langford

A superb image of the Soul Nebula (IC1848) in Cassiopeia taken by member Kevin Langford from Bexley, Kent.

This image was captured over three nights from the 2nd to the 4th March 2025.

Number of images taken = 130 x 180sec

Kevin took this image using an ES102ED APO with 0.7x focal reducer corrector, Pegasus NYX-101 mount, ZWO asi071, Orion NMAG and a L-enhance filter.

The image is a total of 6.5hrs of exposures.

Software used:

Nina to capture data.

Sirilic to stack images.

Siril to processes image.

Affinity Photo 2 to finish.
