“we barely survived a violent past”...?

I, for one, wasn’t around for the last bombardment!!

Well, it seems we were right coming here after bombing.

Thank you Alain for the wonderful images. Congratulations. Well done.

John

Hello John,

 

many thanks for your comment.

 

These are, without a doubt, one of, if not THE BEST moon pictures I've ever seen.  Amazing crispness.... Beautiful!

Hello Josh,

 

i was lucky with low turbulence. I have seen better pictures and i hope i will make greatest pictures but unfortunately, the weather is really bad and it will remain bad for a while. Just have to wait.

 

 

Alain

Hello,

 

2 days ago, a small miracle : clouds have gone away for 3 hours.

 

The Moon was high in the sky but the turbulence was really strong. Collimation was quite impossible.

 

Anyway, the captures were not so bad with C9.25 at F/D 10, IMX178 mono camera and red filter (green filter did not bring any good result).

 

Here are some results (unfortunately, small size because of the forum).

 

Copernicus region :

 

gallery_228659_7680_812846.jpg

 

 

Mare Nubium :

 

gallery_228659_7680_226521.jpg

 

 

Apennins Mons region :

 

gallery_228659_7680_1356739.jpg

 

 

 

I also tried to make a coloured Moon (showing the different kind of soils) using the IMX178 mono sensor camera with RGB filters. I made some tests some months ago but the results were really bad. But this time, it works and i can say it works very well :

 

gallery_228659_7680_1555742.jpg

 

 

A comparison between IMX178mono + RGB filters versus IMX178 colour sensor :

 

gallery_228659_7680_156621.jpg

 

I have always thought the mono sensor + RGB filters will give better result than colour sensor but until now, i did not succeed to manage mono sensor. A small victory for me.

 

 

And the last picture, a mosaic from Archimedes to Mare Nubium colourized with the map of the colours of the soils i made with my IMX178 colour camera :

 

gallery_228659_7680_480361.jpg

 

 

 

You can find those pictures with a better resolution there : http://www.webastro....=143127&page=25

 

 

Clear sky

Excellent job Alain, particularly for turbulent skies!  How many frames did you take with the 178m and how many did you keep in the stack?

Many thanks.

 

Usually, my captures are about 2000-2500 frames and i try to keep the 300 best ones.

Thanks Alain.  I took my very first shots of the moon a couple of nights ago in similar conditions and trying to run through some scenarios in AS!3.  Clear skies!

Here are the last tests with the IMX178mono sensor + RGB filters.

 

Mare Vaporum, Serenitatis and Tranquilitatis region :

And a 2 pictures mosaic :

 

gallery_228659_7680_909703.jpg

 

 

I think it is one of the most detailed and coloured pictures of the Moon we can find on the net.

That's a great job, Alain !

Even if lot of people trust that color is not usefull for Moon, here are proofs of the contrary ! wink.gif

I do not normally post here, BUT these images are just fantastic.  I tried my 178 mono last night using my CPC 9.25 @F6.3 and a 7nm Ha Filter and the results are very good.  I can hardly wait for a clear night any try at F10.  Thanks to Alain for this thread, it has open my eyes to what is possible today....Pat Utah smile.gif

Many thanks Alberic. I do agree, colours of the soils are really helpful to try to understand Moon geology and history.

You made good pictures. A 7nm Ha filter is a bit hard and you will loose a lot of signal. Maybe you could use a normal red filter when the turbulence is high and a green filter when the turbulence is low.

 

Anyway, C9.25 can bring you very very good results.

2 more pictures but this time, just monochrome versions.

 

First, a mosaic showing Sinus Iridum, Plato and Archimedes :

Then, Tycho and Clavius region :

Alain,  Thank you for the info on the filters, I do not have any color filters, but they are readly available and not too expensive.  Thanks Again...Pat Utah smile.gif

Hello,

 

now, something a bit different because this time, the picture i have colourized is not one of my picture.

 

My good friend William Pellissard took this picture of Archimedes (and rima Hadley) region with his C14, using an IMX174 sensor camera. This picture is really amazing and it is my favourite picture of the Moon.

 

I colourized this picture with the colours i get with my IMX178 mono camera and RGB filters.

 

The result is quite good :

 

gallery_228659_8847_1191107.jpg

 

 

Some month ago, i did the same but with the colourmap i get with my IMX178 colour camera. Here is a comparison between the 2 results :

 

gallery_228659_8847_933810.jpg

 

 

Colours differences come from treatment. With colour sensor, i have to decrease red because if i don't, i can't get the fine colours and everything turns red very quickly.

 

RGB filters for mono camera are more selective than bayer matrix filters and i think that's why mono sensor camera + RGB filters gives better result.

 

Many thanks to William Pellissard for his marvellous picture.

 

Alain

Excellent work, and the false color images are especially interesting. I have been imaging the moon with my 8-inch Celestron EdgeHD SCT and a really limited video eyepiece, but I am soon going to get a ZWO ASI290MC camera soon, the one shot color model. It will have seven times as many pixels that are half the size the video eyepiece has, with superior everything else. I can hardly wait to try it out on the moon ahead of the return of the planets Jupiter, Mars and Saturn to the evening sky.

Hello Taras,

 

many thanks your your comment. I am sure you will have great results with the ASI290MC. IMX290 is a very good sensor. For planetary imaging, you should consider an ADC with your colour camera. It could be very helpful.

I assume ADC refers to atmospheric dispersion corrector. I have noticed color fringing before that can only be the work of refraction due to the atmosphere and not chromatic aberration in the telescope. I assume therefore an ADC is for correcting the sort of color fringing in the image below.

Yes, ADC will correct the atmospheric dispersion. As planets are very low in the sky, the atmospheric dispersion is very important and you will have red and blue fringing. ADC will help correcting this.

Hello Jeff,

 

The truth is that William and i are very proud of this work and from what i know, i have never seen anything else on the net but maybe someone made much better.

 

That's why i say it's quite good. I think it's really good but maybe it is not that much.
