Review of 2022

Some of my better images from 2022. I didn't think I done that much this year, having focused mainly on planetary imaging, but in the early part of the year I did do some work on nebulae. 

From left to right and top to bottom we have:

• The California Nebula, which supposedly resembles the shape of the state
• Mars showing its north polar ice cap of frozen carbon dioxide
• The Flaming Star anthem Tadpole Nebulae with the smaller small spider Nebula
• Saturn when it was close to opposition
• The famous Horsehead Nebula and with the Flame Nebula below it
• Jupiter showing cloud bands
• The Jellyfish Nebula
• A so-called 'mineral' moon
• The Christmas Tree Nebula with the Cone Nebula st the top
• The sun showing at least seven active regions or sunspots
• The Soul Nebula
• The Rosette Nebula in the false Hubble Palette colour

And here's a 2023 calendar with all these images for you to print out if desired:

UPDATE TIME !!!

I can't believe that I haven't updated this blog since March 2022 - how time flies.  Unfortunately it's not been a very productive year mainly due to the long stretches of poor weather and opportunities only arising at inopportune moments. 

The main thing that happened this year was that I bought a second hand Celestron NexStar 6SE telescope, a ZWO ASI 224 planetary camera, a ZWO atmospheric dispersion corrector (ADC) and a 2.5x PowerMate (Barlow) for planetary work and so that's what I've mainly focused on for much of the year. It's been another learning curve as planetary imaging is quite unlike deep sky imaging, but I have had some successes and I've managed to produce my best ever images of Saturn, Jupiter and Mars. Still a lot of work to do there though.

In the last couple of months I've been very fortunate to have had the loan of a William Optics WhiteCat 51 widefield telescope off my friend and fellow L.A.S. member Mark Hellaby, who has very kindly let me borrow it for quite a while now as he focuses on other projects in his newly built observatory.  I was mainly hoping to put it to good use at a 'Star Party' in darkest Dumfries and Galloway in November, but very poor weather meant I only managed one night of imaging and one target, Andromeda (shown here).  However, since returning home I have had a few more sessions with it in my back garden and improved my existing images of several widefield deep sky objects.

So, without more ado, I'll set about updating this blog with images I've taken since March and I'll be putting them in chronological order according to the dates I took them.

At Time of Increasing Solar Activity

Here are today's active solar regions (A.R.'s) showing more sunspots than I'ver captured before.  Although the sun emits all wavelengths of light and these combine to make white light, people are used to seeing the sun with an orange colour (caused by the scattering of all the shorter wavelengths but the atmosphere) and so I have increased the white balance to make it appear orange rather than the normal white colour my solar filter produces.

Here are some closer versions of the main sunspot groups being seen today:

A.R. 3163, A.R. 3166 and A.R. 3162

A,R. 3167 and A.R. 3160

A.R. 3165

A.R. 3168

A.R. 3163

A.R. 3166 and 3162

The Flaming Tadpoles and Friends

In this wide field image there are three main nebulae and some partial views of other deep sky objects.  From left to right there is IC405 or the Flaming Star Nebula, IC 410 or the Tadpole Nebula and the smaller IC 417 or Spider Nebula.

In the bottom right corner there is also part of NGC 1912 or the Starfish open star cluster.

Here's an annotated inverted version of this region of the sky:

The Full Veil Nebula

Until I borrowed the WO WhiteCat telescope with a focal length of 250mm, I could only ever image one section of the Veil Nebula at a time.  To get the full Veil Nebula with my scopes I would need to do a mosaic of several images and I haven't got round to trying this technique out yet.  Indeed, this is a common problem for many astrophotographers and so it's very common to see separate images of just the Western Veil (or Witch's Broomstick) and the Eastern Veil rather than the full nebula. Therefore the full Veil Nebula was high up on the list of images I wanted to take whilst I still had access to this scope.  

The Veil Nebula is easily overwhelmed by the number of stars in the region and so I used the technique of removing the stars to process the nebula and then reducing them in size and intensity before adding them back in. Unfortunately this has resulted in the very bright star (52 Cygni) in the Western Veil area becoming quite dull and so I need to redo this image sometime to bring up it's brightness and vibrance. I'm also not terribly happy with the colours so more work is needed.

Waning Gibbous Moon

 Here are some shots of tonight's waning gibbous moon:

Two for the Price of One!

The famous Horsehead Nebula is one of my favourite deep sky targets and one I found it hard to believe I could actually image from my own back garden.  And when imaging this dark nebula in widefield, you get two for the price of one, because the Flame Nebula is also in view in the lower left corner.

The big problem with imaging this fantastic pair of nebulae is the very bright star called Alnitak to the left of the horse's head, which tends to drown everything out.  In trying to dim it's effect, there is a tendency for it to become quite dull, as it has done in my image above, so more work is needed to get the final image I so desire for my wall.

The 2022 Lunar Occultation of Mars

Occultation is where one astronomical object, such as a planet or moon, passes front of another one, obscuring it from being seen.  In this case, the Moon was due to pass in front of Mars in the early hours of 8 December 2022.  In addition, Mars also happened to be in opposition, meaning that the Earth was directly in line between Mars and the Sun. Opposition is when a planet appears at its brightest in the night sky.

I had so looked forward to this rare astronomical event and planned for it quite throughly, but in the end I was frustrated and foiled by the cloudy weather. I set up early in the afternoon and had quite a few practice shots during the early evening when the skies here were crystal clear.  

At first I thought I'd stay up all night waiting for the main event when Mars was occulted by the full 'Cold' Moon at around 4:45am, but in the end I decided to get a few hours sleep starting around11:45pm. When I got up at 3:14am, the skies were still clear and Mars was a lot nearer to the moon than when I had gone to bed.  However, when I returned from making a quick cup of tea, everything had changed!

The clouds had rolled in totally obscuring Mars and the Moon at times and time was running out.  I'd focused everything previously, so I wasn't concerned about that, but the exposure time was giving me real problems and I had to keep adjusting it manually with every passing cloud.  This really wasn't easy and was certainly very frustrating.

Consequently, I couldn't see Mars at the all important moment of occultation, so I just left the camera video running whilst I hoped for the best.  I was also trying to take some manual single shots with my DSLR and big lens in a sort of belt and braces approach.  In hindsight this wasn't such a good idea as my attention was constantly switching between the two systems.

At first I thought I'd totally fluffed it, but with a considerable amount of processing I managed to resurrect these two shots from the stacked video.  They're quite disappointing really but they are all I've got and at least I witness the event.  

My best shot probably came after the occultation had finished and Mars was on its way to set in the western sky. You can see how cloudy it was from the colours in the sky and the lack of clarity in the Cold Moon's surface features.

If You've Got Heart, You Gotta Have Soul!

The Soul Nebula is partner to the Heart Nebula in the constellation of Cassiopeia.  The Heart Nebula was my first go at using Mark Hellaby's WhiteCat 51 telescope last month. Unfortunately, not even the WhiteCat is wide enough to capture both in one image and so I had to image them separately. Tonight's target was the Soul Nebula - well, if you've got Heart, you gotta have Soul!

I also managed a bit of time on the Elephant's Trunk Nebula on the same night. It's nice to see it in a widefield setting as my previous images wit a narrower field of view concentrate just on the Elephant's Trunk itself.
