Hello everyone,

 

I attach 2 high resolution views of aforementioned craters, taken at 6 meters of focal lenght and with Blue filter (Clavius), Red for Copernicus.

Usual setup :C8EdgeHD+camera ASI174MM.

Nice images Vinny.  Can you provide an estimate your seeing conditions?

Thank you all guys!

 

Nice images Vinny.  Can you provide an estimate your seeing conditions?

Seeing was good, with weak jet stream, but unfortunately there was a  lot of moisture (>70% HR) and transient clouds.

I ve seen your result with Copernicus in the other 3d, resolution is quite similar but you declare average seeing. This is motivating ! waytogo.gif

 

Clear skies,

 

V.

Thanks for the information Vinny.  Thanks for the compliment on my image as well.  I looked and saw the resolution was quite similar.  I was in fact encouraged by your image as well!

Hello

For a C8 it's very good and nice processing.

Clear skies.

Nice images Vinny!  I'm curious as to the choice of a blue filter for the Clavius image.  It would have been interesting to compare with a green filter, as I've yet to encounter a situation in which a blue filter actual increases resolution, and unfortunately it usually produces a worse image than green or red, but your image does look very nice.  For a C8, the only area that could potentially be improved in even better seeing is that there is slight blur present in the image, that could potentially become sharper in better conditions (although probably without much additional detail), and I wonder if it might also be improved using a different filter other than blue.

Hello Tom,

 

thanks for your question. Since I have ZWO electronic filter wheel ( couple of months) changing filters is a breeze, and this is leading me to experiment more with them. So I tried in rapid sequence R, G, B, IR, RIR, and found the blue filter gave me the best output on video (seeing being equal, roughly). After postprocessing, I found differences were actually so subtle to be almost irrelevant (see below) and I used blue channel only cos I had more good frames to stack.
