Venus at Inferior Conjunction – 25th March 2017

On the day of Venus at Inferior conjunction, I was hoping to catch the very thin crescent of the planet just over 8 degrees from the Sun.

It was always going to be a challenge in the bright daytime sky, but as the Sun (and Venus) got higher, high wispy clouds crept across the sky, producing a very “nice” solar halo.

This was going to make the sky around the planet extremely bright, making contrast between planet and sky very difficult.

I used a 120 mm refractor for safety purposes. I didn’t want to risk using the Mak-Newt that close to the Sun.

All lined up and projecting the Sun’s image, I then told the scope to go up to Venus.
It loyally obliged and I was pointed at a very bright patch of sky.

Luckily the scopes were positioned in a way that the main scope, with it’s cover safely on, shaded the end of the refractor and finder scope.

Looking through the finder, I moved the scope slowly around, making sure I didn’t go towards the Sun. The contrails and cloud could be seen easily, but no sign of the planet.

With my usual perseverance, I  kept at my vigil and the whiteness started to look a little more blue. It was still very wishy-washy, but it had cleared a little.

Then I spotted the thin crescent planet in the finder. Once found, it was a case of moving the scope so the planet was centred then looking through the main scope. It was there!

It looked absolutely amazing. So thin and bright. How had I missed it before I found it?
I cranked up the magnification by changing eyepiece. The crescent was wildly dancing about from atmospheric turbulence.

Now to get the webcam on it and focused. Now that’s easily said than done! Especially trying to work on a computer screen in the sunlight. I faffed about for ages, but finally I could see the small out of focus crescent on the screen. A few adjustments and I took my avi to capture the moment.

I then decided to go live on Facebook.

Once this was done I put in the 2x Barlow Lens to magnify the image.
Then after a lot of messing around (again!) I finally got a bigger image back on the screen.

I took my avi to capture the moment and then went live once again.

Thank fully the image was a bit better focussed this time.

Objective achieved, I was a very happy man.

It was clear that night as well, but I was so tired, I gave it a miss.

No dedication!

 

A Tasty Comet Sandwich – 20th March 2017

After I got back from work, the rains had cleared to leave a clear sky.

Venus, just 5 days from conjunction was very low after dark, so I shot out there as soon as I got home to catch it before the Sun set. It was easily found, very bright and extremely thin. A great view in the scope, and phase easily visible in the finder scope. I took some colour webcams, and broadcast a live video on Facebook, before switching to the Venus filter and monochrome. The atmosphere was extremely turbulent, but the filter helped enormously.

The lower picture shows just how much the planet has changed over the last couple of weeks as it approaches inferior conjunction. This occurs on the 25th.

After dinner, the sky was dark enough for some comet hunting.
Comet 41P which is located close to The Plough was first. About 8th magnitude but brightening as it approaches perihelion. It will be close to M108 and The Owl Nebula on the evening of the 22nd.

After that, my next target was Comet 45P, definitely fading and looking very diffuse now.

Rising in the north eastern sky, and just clearing the neighbours house, was Comet C/2015 V2 Johnson. Now this is what a comet SHOULD look like.

 Last but not least, Big Jupiter was rising in the eastern sky. So, the colour Webcam came out. A quick Live feed on Facebook before capturing an image. Now that is a VERY tasty Comet Sandwich.

Venus and Moon – 9th March 2017

On the evening of the 3rd of March, I went out to try and catch Venus in the western sky that evening as it approached inferior conjunction on the 25th. I wanted to see how much the size and phase of the planet had changed since I last imaged it just a week ago on the 2nd of March. Despite the evening looking very murky and the planet constantly moving behind cloud, here’s the result with the DMK21 camera.

Then it was onto the bright gibbous Moon over in the eastern sky.
I rattled off a number of images with the DMK41 camera.

Venus and Moon.

Hannington Vintage Tractor Club – Monday 6th March.

On Monday the 6th of March I will be taking Hannington Vintage Tractor Club on a wild ride touring out to the very edge of our observable universe.

I will be giving my Whistle-Stop Tour of the Universe (Hitch-Hiking on a Ray of Light) (Or should that be Tractor Beam?) presentation to them.

So let’s hope that they strap themselves in and get ready for a journey that really is out of this world.
(Of course, it’s really just a good excuse to show some beautiful images of our wonderful universe).

2P (just) Moon & Planets. 2nd March 2017.

On the evening of the 2nd it started off looking nice and clear.
A nice crescent Moon and Venus, both extremely bright plus Mars were shining down.
As soon as it started to get dark, I was determined to get a decent crack at Comet 2P (Encke).
It is located just below Venus and sets really quickly as it approaches perihelion.
I got the scope first centred onto Venus, then quickly about 10° down to the comet. It was just visible as a greeny-blue smudge on my subs, but the brightness of the sky overwhelmed everything. I took 20 15 second subs, but as the sky darkened, the comet sank below the level of my fence and was soon lost. I soon found out that I couldn’t stack the images in the usual way as there were not enough stars.
So here’s the result of removing the bright background and stretching a single sub.

The Newton’s rings reminds me of the Loony Tunes ending. Just waiting for Porky Pig, to pop up and say “Th, th, th, th, that’s all Folks!… Hopefully more from this comet after perihelion?

So onwards and upwards!
Venus next. So in goes the UV filter. No cloud detail visible, but considering the phase is a only 0.15, I’m not really surprised. This brilliant planet will soon be starting to get lower in the western sky as it approaches the Sun, reaching inferior conjunction on the 25th of March.

Downwards again. Mars was a little higher that Venus, so UV filter out and try and tease out a disk.

OK, I just managed to get a small disk and perhaps a hint of the polar cap. But I’m not 100% convinced. It is such a small diddy disk.

At this point the sky was now getting a lot hazier, clouds were thickening.
So my next target was of course The Moon.
DSLR first.

Much greater detail captured using the Webcam.
Then I settled down to capture some more detailed features with the webcam before the sky became totally unusable once again. 🙁

Comet 45P/Honda-Mrkos-Pajdusakova

Comet 45P/Honda-Mrkos-Pajdusakova is now easily visible in late evening / morning sky (When the clouds allow us to view it).
Moving rapidly northwards the comet has lost the tail it had prior to perihelion, which occurred on New Years Eve 2016.
It passed closest to Earth  on the 11th of February, passing less than 12.5 million kilometres away.

Despite losing the tail, its post perihelion appearance has swollen markedly, showing a large bright green coma.
Its close proximity to the Earth means its apparent movement is very rapid. If you are taking images, they will have to be fairly short to stop the comet blurring, unless you can guide on the comet nucleus itself.

45P’s magnitude hasn’t quite reached predictions, but it is still a healthy 7th magnitude, so is easily followed in binoculars or a small telescope. Some recent images show that it may be starting to develop a straight ion tail.

This stunning Image by F. H. Hemmerich shows the tail really well and was Astronomy Picture of the Day on the 12th of February.

Image result for comet 45p

Use the map below to find the comet as it passes through Coma Berenices and into Leo.
Its magnitude will quickly fade as it recedes from the Sun and Earth.
Let’s hope for some clear skies now…

Comets to finish Doris’ Day

After a day of storm Doris battering the country, it cleared to a reasonable evening.
I got out ready for Comet 5P Encke, but by the time the clouds cleared, it was far too low in the western sky.

Once properly clear, I slewed the scope over to capture P45 Honda-Mrkos-Pajduáková.
It was in the constellation of Coma Berenices and heading towards Leo.

Comet45PDenoiseIt is huge! I had to use my 80mm refractor to get most of it in.

I then went across to Comet C/2015 V2  Johnson.

This is a much smaller compact comet, with a slightly curved tail. This cropped image was taken using the 190 Mak-Newt.
