Enough ...??!!

I know we may be getting too much Jupiter and Moon (is that possible?!) but as they are looking rather splendid and it'll be something else's turn soon - Orion, Saturn, etc. let's stick with it.

The Jovian system again here and the Moon with some highlights.

I have also found a superb Moon primer on the Interweb here.

Both photos are from a 102mm Mak (1300mm fl) at prime focus using a Nikon D40.

Normal observing was best with my 15mm Meade Plossl (86x).

The Moon, 11 days Old




Apologies to those who are bored with moon pictures but I thought it would be a good comparison to show the moon just two days apart.


When these shots were taken, 19-11-2010, the moon was 11.77 days old and 251.601 miles away. It was also at 90% illumination so features like Tycho, where as they are just visible in the pictures below are rendered almost flat when viewed face on. Depending on the skys tomorrow I will try and get a shot of this again as Crater Schickard looks very impressive if the light is right.





Finally, as more of the surface is revealed what were prominent features before start to look flat as you view them "face on". However Crater Copernicus, 2/3rds up on the right hand side above Tycho, looks impressive with it's ejecta clearly showing as opposed to the picture of the moon at 9 days old where it looks like any of the other craters, all be it deeper.

To put the record straight ....

There has been much consternation (?) about my image of the Jovian system a few nights ago. This is to set my good friend (Al's) mind at rest. Here is a screen shot from Stellarium timed to the night in question.
Thanks to all the good folk who took time in trying to answer Als questions.

The Moon, 9 days old




The last 2 weeks have not been much good for spotting anything other than cloud but last night, 17-10-10 the cloud parted and the stars were back.

These are my latest, and in my mind, best pictures.

The moon was 9 days old and approx 245,000 miles away, it was also at 75% of it's full brightness so the views in the scope were quite clear

The top picture shows an untouched picture of La Luna in all it's glory.

The middle shot is a close up, using a 10mm eyepiece and clearly shows Crater Bossingault, which is 131km in diameter & Crater Boguslawsy which is 97km diameter toward the bottom of the picture and Piccolomini at 88km diameter at the top of the two deeper craters toward the termination line.

Excuse the artistic license on the last shot but by rotating the image you get a more "Apollo" view. I'd seen this done on other sites & thought I'd give it a try..

By Jove

This image of the Jovian system was taken last night. I still haven't got the exposure correct, but shows clearly the four Galilaen moons.

Forget East and West, Look Up!

Last night I decided to look for something different and decided on C39 (or Mel 20 depending on which catalogue you use) and aimed the tripod at C39 using the given co-ordinates. It said it was in Perseus but I don't think I quite understand how star charts would "wrap around" your head if you looked at them yet. Anyways.....I pointed the telescope almost straight up into Perseus' "Sword handle" and, my word, forget your East and West, look up! It's my first galactic cluster and I was amazed at the 100's of stars visible in the 10mm eyepiece. As I moved the slow motion controls backwards and forward there was just more and more stars. I will try and get a picture but in the meantime the picture, on the right, is an image taken from the European Southern Observatory. This is a wide-view picture of what I saw.


In future posts I will try and take my own picture of the cluster so we can compare and contrast between the images taken in a Sheffield back garden and ones from the European Southern Observatory!

The new scope

So, as it was the first clear(ish) night for a while I thought i'd give it half an hour and check out my new scope.
I had to set up low down in my decked area so that I could best avoid street light glare and also someone's security light! (Turn the damn thing off when you're at home!).
The scope is a 102mm (4in) Mak. I stuck to a low power - 52x, so to maintain a wide field.
Well I am soooooo impressed by the new scope. Checked out Jupiter - only Northern band visible still and the Red Spot not in transit.
All four Galilean moons were clearly visible. Then I swung east to the Andromeda Galaxy M31. This never ceases to amaze me. The central "bulge" clearly visible.
I then went on a hunt for Comet Hartley, but couldn't find it. What I did observe was the Double Cluster just South-South East of Cassiopeia - a lovely sight.

The Jodcast

Just thought i'd let folk know of one of the many on-line resources myself and Al use which is the "Jodcast".
The podcasts are also available free via iTunes for those with iPods.
There is also a related site to get a low-down on the night sky month by month here: http://www.jb.man.ac.uk/astronomy/nightsky/

I Can See!

Last night I set up my new scope (IE finding Vega and aligning the RA ring so that it read 18:36) and decided to have a quick scan around.

The sky was full of wispy clouds but there were many tempting sights for me to find up there. So initially, I went for Jupiter, since it is so bright and easy to find. My first sight amazed me. I’m using a Celestron 102mm spotting scope with a 10mm eyepiece so wasn’t sure of the detail I would be able to see. I literally took a step back once the cloud bands on Jupiter were revealed. I say “bands” the Southern Hemisphere ban was missing which would have made it easier to see the red spot if it had been facing the earth (it wasn’t). I also saw 3 of it’s 4 moons, which they were I can’t be sure but my image looked liked MJ’s post and picture of last month.

The point of this post is to explain the superlatives I may use when I do locate objects of interest. I am still in awe of the things I can find with my relatively cheap equipment. All you need is a little patience and and a half decent star chart.

Next on the cards (and the weather looking good for tonight) is Andromeda. I know roughly where it is but I’ve still to find it in the scope. While I'm in that area as well I may seek out Hartleys comet. But one step at a time and all that.

Monkey See, Monkey Do

As my learned friend has given a brief synopsis about his interest I thought it only wise to include mine.

My interest stems from my brother who had an interest in stars. Back in the early 80's, along with my dad they mounted an old brass telescope onto an improvised "tripod" using an old broom handle and 2 bits of wood. My brother taught me the where the Plaides, Cassiopeia and Orion were and, thus, a spark was lit.

I was a naked eye astronomer until about 8 years ago when I bought my first scope but having little patience my main target was the moon as I could find it without too much trouble!

Most of my astronomy is still done with the naked eye and as a "fair weather camper" I'm always amazed to see the multitude of stars when out in the field hitherto unseen in the City. It is with this in mind and my fellow bloggers enthusiasm that I now take to the garden on a clear night and look heavenward.

Comet Hartley 2

You should deffo try and see this!

Memories

Just thought that I would give a little background as to my interest in all things Astronomical.
It was Christmas 1981, I was 10 and was given a 3” reflector as my “main” present. At the time it was the best thing ever (I now know it was really a “toy” scope). Never the less, it opened up a whole new interest for me – I could always get a good view of the main points of interest – The Moon, Jupiter, Saturn, Orion and Halley’s Comet. I also used my Dad’s 10x50 binoculars masking-taped to his old Velbon tripod!
I joined the local Astronomy Society but even at that young age realised it was run more like a Gentlemen’s Club (and still is to this day as far as I can see – what a shame). This whetted my appetite even more as we did at least get to use the 18” reflector that they had in a dome, my main memory being that of seeing Saturn just sat there in the heavens.
The rest is history really and I have gone in and out of my interest for years, but recently (with my very close family friend who I share this blog with) I have become more and more “into” it. I think to some extent fuelled by recent events and personalities – The International Space Station, TV programmes like Wonders, Prof. Brain Cox and of course Patrick Moore and Brian May (eh?!) – You know, bushy haired guitarist with Queen – he’s a scientist!
