Hi all,
this august, José Luis and me have made to new photos: the Moon
and Messier 31.
For the first, we made 114 individual exposures, begining with
4 second ones and ending with 1/200 sec. exposures.
Messier 31 was photographed with a Vixen Newton and a cheap
second hand Konus newton (125$ OTA <g>). Seeing was excelent
during the two nights, but the Vixen coma corrector is not
too sharp... and it shows some lateral color on the stars.
Definitely, we will go for another coma corrector...
The two photos we assembled linearly, putting the shorter
exposures over the saturated areas of the longer ones.
This makes a high dynamic range, linear image. The dynamic
range on this images is so great that we have processed
them wwith 64 bit per channel precision. In fact, the Moon
image needs more than 3 million gray leves to be represented
in a linear way.
Once combined, no layering techniques were applied to the
images to show the information over the whole dynamic range.
This process was done entirely with our own wavelet
techniques. All the processing was made in PixInsight.
For the moment, you can access the gallery through this
address:
http://c300d.pleiades-astrophoto.com/Gallery/Gallery.html We are going to change the DNS configuration of Astrofoto.es,
so the domain will be unavailable during some days. The
address above works perfectly.
Well, we hope you will enjoy it.
Regards,
Vicent.
