Christmas Presents

Various Astro, Space and Sci-Fi related pieces of interest… oh, and Neil Armstrong!

Not posted recently, so here are a selection of pics I’ve been collecting that I thought would make an interesting contribution…

So to start, an update on my Lego Saturn V Christmas present. Andy has been helping ad-hoc as well!

Completing the second stage…

Very cleverly designed…

Once finished it should stand a metre tall! There is a ‘link’ back to the Saturn V / moon, later on…

Next, a picture of our magnolia in full bloom… “Stellata” (meaning star), taken at 6.55pm on Wednesday 18th April…

Later on, a beautiful crescent moon and the ‘Evening Star’, Venus – Julie and I were out for an evening walk. Taken on an iPhone 6 at 8.38pm.

Then another, a tad later at two minutes past 9… nearly home…

Next is a picture of the moon taken through a 13mm Ethos eyepiece attached to my TEC140-ED APO refractor – just hand held with the iPhone held up to the eyepiece. This was from Friday 20th April, whilst waiting for Andy to turn up (his observing report can be found somewhere on here!)

Oh, and a picture of me setting up the gear (didn’t know Jules was hanging out of the bedroom window taking this…), I think I’m in the throws of setting up a WiFi connection from the Nexus device (that reads the mount’s encoders) to the iPad Air 2 (that runs Sky Safari Pro 5).

Here is a process of a friend’s Solargraph we made for them ready for the summer 2017 Solstice – it stayed in place ’til the winter Solstice and they passed it back for processing in early April…

Raw scan (that Andy kindly did for me).

And the processed version! We’re not sure what the bright squiggly line is!

Next we jump to the RAG meeting from Friday 27th April – featuring guest speaker Paul Money (part 2 talk about the Voyager probes and their journey to the gas giants and beyond)… captured in ‘full flow’!

Next a picture from another evening walk, a lovely sunset with the three spires of Lichfield Cathedral and St. Mary’s Church (in the town centre)… Monday 30th April at 8.18pm.

Julie is a French and German teacher… she told me on this walk that tonight was “Walpurgis Nacht”, the night when animals can talk, see the link below:

On the 1st May, in the old calendar, it was also the start of summer… you wouldn’t know it though with the weather this last week… we’ve even had to put the central heating back on in the evenings!

…and another from Wednesday at 9.02pm… the Cathedral from Stowe Pool.

…and later still, at 9.30, Venus shining brightly…

Now some of you may be aware that my post was made redundant at MandM back in February. Well I’m now back in full time work as the photographer at Richard Winterton Auctioneers (Richard is on telly quite a bit if the name rings a bell), based in Fradley. So far I’ve photographed medals, coins, furniture, art, ‘military’, toys, silverware and jewellery.

But we’ve also had some other interesting ‘lots’ come in which are being prepared for future sales…

How about this…

A full sized Dalek and yes you can sit inside and move him along!!! He needs a bit of TLC. This is a little Photoshop work I’ve done on him for our social media feeds (the Andromeda Galaxy background is my own from some years ago!)

We also have going under the hammer this retro playsuit based on the original ‘TV Serial’.. I wonder if some of our older members remember wanting or even having this ! 😀

Lastly, on a far more serious note… take a look at this letter which came in to be valued and put up for sale!

Note the early NASA logo, date (only a few days since getting back from the moon) and of course the signature!

Hope you enjoyed this rather varied blog entry!

LOMO Biolam Microscope restoration.

As you’ll have gathered, Andy got me an old LOMO Biolam microscope for Christmas. Included in the sale were an assortment of extras ‘upgrades’ (all in their own wooden boxes) to the original base unit (most I don’t think have ever been used), including a binocular head with a pair of x7 and x10 eyepieces.

Being 41 years old, it needed some TLC – the main issue being the infamous ‘Russian Tank Grease’ originally used!

You can tell it’s age as the serial number contains it’s year of manufacture – just like Takahashi do, so the ’77’ is 1977.

This instrument is still a ‘LOMO’ version, later, it was also made and marketed under the Zenith brand (we used their cameras at art college!)

Over time, this grease has solidified (think your bonfire toffee apples), so most things that were supposed to move were either very stiff or just plain stuck.

Not being very ‘DIY’, I’ve spent the last few weeks tentatively stripping it down and soaking various parts in white spirit and WD40.

 

Andy came round just after Christmas and we had ‘first light’ – this image is of a Lilly Ovary, iPhone 6 held up to the 10x eyepiece in the Binocular attachment (adds 1.5x mag) and a 20x objective (so 300x)

It was pretty tricky to achieve focus as the main (coarse focuser) was lumpy and the fine focus unit inoperable….

The microscope (thankfully) turned out to be pretty easy to take apart.

Below, the main/coarse focus unit (after spending a week in a bath of white spirit). Brushed clean with my old tooth brush and re-greased with a modern silicon alternative.

 

Image below – bottom of the ‘stage base’ – the bit where you place your slide (‘rotating stage’ also stuck!) This shows the silver-grey fine focuser mounted on the side.

Most of the microscope is cast metal and brass. The only plastic part was this strip of gearing for the condenser (the unit that focuses the light source onto the slide/specimen). The two screws though caught me out – the top being countersunk and the lower a pan-head!

The brass is ‘pre-polished’….

Below images (x2) – back of same ‘stage’ part….

…..and with gearing removed….

The biggest issue was the fine focuser. The actual unit is self contained, like the inside of a watch and ‘runs- dry’ – so no grease. Whilst it worked on it’s own, I could not get the fine focus to work once everything was reassembled…

The large metal pin (above) sits in that circular recess shown below in the middle of that brass piece. Inside the main cavity sits the fine focuser which mates to the fine focus gearing/knob just seen in the shadow right at the back.

It turned out that the brass part (with circular recess) is supposed to freely move up and down with a turn of the fine focuser…

….the movement dampened by a large spring that sits inside this circular recess on the other side (top). The spring is held in place under tension by the serial number ‘date’ cover shown earlier.

 

Once we had worked out how this works Andy………. hit it…… (carefully) with a hammer….(!!!) after judisious use of WD40. That freed the brass dovetail allowing cleaning, polishing and re-greasing…

41 years of grease (finally) removed !

Amazing what a bit of Brass can do!

Once all back together everything finally worked!

 

Andy headed off and I finished polishing up the chrome objective head and attaching the X/Y upgrade to the stage.

Later in the evening I popped over to Andy’s to try the microscope out. I still have the condenser upgrade to sort (Russian tank grease again) and then sort an LED / Halogen illuminator to replace the 15w bulb version (itself an upgrade over the supplied mirror).

 

Andy’s calibration slide – each line is 0.01mm apart.

 

The moon….?

 

ET’s hand !
