Been playing with libration this evening (not libation!) Here's my image from the 6th of April showing Maria Marginis and Smythii. Goddard, Dorsa dana, Dorsum Cloos all visible and a good portion of the Maria. The white line is mean libration - the normal limit of visibility when libration is zero. And the same region viewed from Earth On the 9th of May, Goddard etc are well and truly behind the limb. This will be a fantastic observing tool as well for me.

Not at all working tomorrow and won't miss it one bit..... Is what I'm telling myself.

There are some fantastic ways to visualise topography too. This really isn't the best image to do this with but you get the idea. Take Clavius from one of my images, deformed to show an aerial view. Take the same FOV from the WAC Global Morphologic, multiplied (in LTVT) on to the digital elevation model. Blend the 2 images together in Photoshop using colour blend mode and mask off what you want to retain from your original, in this case everything that's not Blancanus and Clavius. Need's better imagery as I said but it's a start.

Onto the 14th of April now to see what things look like as the sun is setting. First, the full disk And on to a close up LTVT has a gamma adjustment allowing a rudimentary stretch which is really useful pulling out the terminator detail. In this close up the gamma is stretched to 2 And an aerial view of the same, all my photo, just deformed. And an elevation model of the same view. I love how accurate this thing is, it will very much be used to plan observing sessions

This is getting interesting now. Take a crop from my image showing Copernicus and environs: Add LTVT's elevation Rendering of the same view: Blend various versions of each using adjustment layers and you produce an enhanced view that shows off the relief and the variation in intensity of the ejecta blanket quite nicely thank you. A better image will produce better results I'm sure but this'll do for a start.

What a fantastic tool this is. Annotating is a doddle, it has all the IAU official designations and as I said it's as simple as right click, find and label - giving this from 06/04 @ 22:26 It can also read LRO/LOLA elevation data allowing contours to be applied and generating a pseudo 3d view at your image scale/field of view for that time from your location - the contour map shows I still need to work on calibration accuracy a little. Finally, and this is my favourite feature it can deform your calibrated image to simulate an aerial view: Next up to see if I can use these 3d renderings to produce a depth map and make 3d renderings of my images. Who needs clear skies anyway.

The right click contextual menu has a useful 'find and label nearest feature' option as well as 'nearest feature and all features sharing same name' which is how these labels were generated rather than automatically as in the first 2. (This one really shows how poor my calibration is with reference points and time but you get the idea)

As you know, I like annotating my images, it helps me to learn features which enhances my observing at the eyepiece in many ways. Until today I've been using the Virtual Moon Atlas and Rukl to eyeball features and manually label them in Photoshop. No more I say, as I've just discovered this https://ltvt.wikispaces.com/LTVT It's plate solving for lunar images and it's marvellous. A few rough first tries attached to show with an early evening image from the 7th. The geometry is a little off as I only entered a rough time of capture but you get the idea. It knows libration too so accuracy is good. Next to fine tune with an image where I know the exact time of capture and play with digital elevation models to do contour lines And it works with Wine if you're a mac user. Love it.

Fantastic cake, save us a piece won't you! Hope the big day went well, congratulations to you both.

Great review Jules, I do hope you get that affinity over time, get out to the dark sites and I'm sure it'll come into its own with DSO, and enjoy those crisp lunar views at home mate.

Anything not covered in cloud would be my suggestion ?

Gorgeous, enjoy it and I hope you get first light soon.

A few more tonight. 40x and 125x. Wratten #58 seems to help with this complex form of imaging.

Posted in the wrong thread

It's a fix I tell you... oh.... wait.... humble, honoured, etc etc. Years of work, wouldn't be where I am etc.

And one more.

A few more just now. Archimedes area

Just took this. Was enjoying some vis on the early evening moon after a nice afternoon imaging. Seeing excellent so I have the 1000mm frac with 8mm, polarizing filter and 2.5x Barlow on and the views down the terminator are lovely. I simply had to capture it and enter the stupod so here it is. Captured on iPhone 6s and processed in ps express a bit of sharpening, cropped and converted to mono

A worthy winner for sure. Terrific image.

I'll do my best John.

It's lovely. I hope there's more to follow.

It was bootiful in the vis too Chris

Thanks Charl.

Could prove difficult.....

You know you want to Dave
