Mars and Moon 31-01 breaking a drout

[ReaPerMan]

Haven't been able to get out for a long while now so having finished my latest stint of night shifts i had to get out and try my set up on the new EQ6Pro mount that I got last weekend. Sporadic cloud so i didn't get much chance to get multiple images so I grabbed what i could before it set in or i collapsed from lack of sleep.

I have been looking forward to trying to get Mars, It was very jumpy and wobbling like a belly dancer in the breeze but this was the best pic that i could salvage from the 2 avis that i could get before the cloud arrived.

I also took this nice hires crater pic with the intent of finding out what it's name is but so far i cant track it down. Ideas anybody.

C9.25, 2.5 Powermate, Celestron Neximage CCD, Registrax 4, Photoshop CS4 and Astra Image plug in.

Hi Paul,

It would help in identifying the craters in your image if you supplied a little extra info.

What is the orientation of your image, which direction is North and East.
I have been looking for this field in my Moon atlas.

On 31st Jan the Moon was 1 day past full so I would expect the eastern limb to have exhibited just a little shadow while the western limb would have been lit to the edge.

If you can supply this info I am sure that I can identify the features.

Hi Trevor,

This is why I am at a bit of a loss, I believe that this is the south west located on the terminator line at 1500 UT 31/01/10. I made a mental note of it's aproximate location (first mistake) and i haven't been able to find it since. :shrug: Sleep deprivation does silly things to common sense!
all the best

I think it is Petavius

Hi Paul,

Clayton is right on the money, it is Petavius. The problem is the orientation of your original image. I just loaded it into IrfanView and if I do a vertical flip then rotated the image left it is then orientated correctly and matches the image posted by Clayton and also my copy of Antonin Rukl's Atlas of the Moon.

Paul, it might pay you to download IrfanView, it is freeware and an excellent little program for astro images. For positive id of detail on your future Moon images remember that you need to change the orientation of your image to make it a lot easier, being upside down and back to front makes it a lot harder.

It is indeed Petavius. And Snellius at 7 o'clock.
Your image back to front that's why its confusing. Top is East.

Hi again Paul,

Have attached your image after doing a vertical flip and then rotated the image to the left in IrfanView.

Cheers
Trevor

PS North is up and East is to the right.

Thanks Guys that was great work! I will pay attention to the double flip next time. I was using that atlas myself and missed that section as i must have got myself well and truely turned around. I like this pic and now that it is identified i like it even more :D

Many Thanks paul

I found this amazing top down shot of this crater taken in the 1960's by a lunar orbiter! really shows up the detail in this crater.

I figured it out with VMA, after doing a couple of flips to get the orientation right.

Wow! Nice shot, it looks sort of rectangular, and how come the obvious rille on the top right doesn't get a number??
