Stub Mandrel

Perfectly safe if you can fit a patch over the hole that you are 100% happy is secure. No less risky than glueing the film into a card support ring, which 100s of people have done before you.

Congratulations all!

Interesting and clearly shows how things improve with processing.
Is this shot on a webcam or derivative type set up?

My ASI120MC on my 150PL.

I found I'd uploaded this clip of the moon taken through my 150PL. It's a good example of what to expect - especially the impact of seeing on how (un)steady the image is.

The still image below is the result of processing the full length video, rather than just this short clip.

And yes, still struggling with these tiny upper thrusters...😡

If you use Cura, try the 'experimental tree support' I've used them to print the front half of the top of my LEM and the thrusters came out a bit rough but not too bad considering they are only about 2.5mm long.

Vastly better than Autodesk Print Studio's tree supports, much stronger but use a lot more material so slow to print.

Rats, I did a compilation of the Apollo landing sites a few years ago!

Which one Neil...?

This one: https://www.thingiverse.com/thing:866068

But with the unsupported base here: https://www.thingiverse.com/thing:2137325

Not sure whether to use the one or two section upper part.

(by the way, most of the NASA Saturn V is solid, making it heavy and slow to print, although I suppose you could use a very low fill percentage).

Is the general consensus a yes? It's an interesting question to be sure. I told my wife the other night that the colour in the beautiful astrophotography images we see is fake, so she asked what the REAL colour of these DSO's are...and i had no answer. Is there even an answer? I know most of the detail in the images comes from wavelengths shorter and/or wider than visible light.

The colour in RGB images is 'real' just typically with the saturation turned up so pale colours become stronger. Like redoing a subtle watercolour in poster paint 🙂

The odd thing is that in general they would look the same if you were closer to them as although closer the light would come from a much more spread out source.

Having a go at the LEM off Thingiverse.

Found it!

I'd love to see the finished rocket.... 

There's a photo SOMEWHERE probably on here as well, but I can't find it..

Works on both these examples for me, especially impressed with the lizard...

I have read, and subsequently prooved to myself, that it's possible to see colour in the moon IF your eyes are totally non-dark adapted, forcing you to view it only with the colour receptors. You can make out just very faint tones to the seas.

I printed the NASA Saturn V, about a metre high with 0.5mm nozzle. Looke great when painted but kept falling over and breaking so I ended up recycling it 😞

Goldie the ED120 out for Jupiter viewing just before packing up. 

If you look in the top right Jupiter is just visible over the LP from a neighbours bathroom which seems to run an LED light from dusk till dawn. 

 

Show them that photo of your scope pointed near the bathroom and they will probably draw the curtains... 🤣

The chair of our Astronomy Group got this pic of me failing to get my guidescope to focus on Friday night.

Luckily the dual rig included a DSL that didn't need guiding.

If you check the forecast in the AM and you have it set to centred on Midnight, it has to show part of yesterday in order to be able to show the forecast for the current AM.

We are working on some changes to Clear Outside this year and the 'views' is one thing I want to tidy up and have a more intelligent view which shows you the full days hours centred on Midday if you check in the morning and then the over night Center on Midnight view if you check in the afternoon - I think that would be more logical.

Hi Grant, that's even weirder behviour!

Up until  the actual time of 11:59 the top line displays the hours either side of midnight yesterday/today.

At the stroke of noon, it changes to displaying the hours either side of midnight today/tomorrow.

But the labelling on the left does not change.

This is confusing as in 'centre on midnight' mode the midnight displayed can be either the one before or after the day indicated.

For consistency it should be displaying the day name for YESTERDAY against the top line up until the change at noon to make it clear the weather on the top line starts on the day that has passed. Also all the days below need to be moved back one when in this mode (and the time is before noon).

Single frame. Showing the effect of no astro dark & no cooling on a hot night (28 June).

Just shows you the difference that stacking makes - the result of piling up 135 of these was almost passable!

Have you considered a medical grade waterproof keyboard and mouse?  😀

I'll be dead before I use up enough cheap ones at £5 a year!

Minor bug... centred on Midnight Saturday it's highlighting 11:00 am on Sunday as the current time, but it's 11:37 am SATURDAY.  I normally use centre on Midday so I haven't noticed this before, but it appears it gets confused when the current time is before when the display starts.

Cheap Advent mouse but nice to hold and works well.. 👍🏻

My ability to douse keyboards and mice with coffee/tea means I always have Trust or Advent ones...

Just a basic laptop but surprised at how nice it is for the price. Doesn’t feel cheap and everything moves along nicely.  Won’t be doing any image processing with it. Just for capture. . Will save to a micro SD card.

Hah! I had an identical mouse in my paw when I saw that pic!

In the absence of a truly independent test I'm not going to lag mine - I suspect rapid cooldown is more important.

My 150PL busy imaging away after a RAG meeting at Rosliston. A bit of a galaxy fest on 29 March.

Took a detour via Screwfix after swimming today to collect about 20m of trunking

It's definitely cheating when your trunks stretch the whole length of the pool.
