Re: Flats from near full disk?

Hi Maurits Yep the second image shows the info is all there and easy to bring out once it has been flattened. I will be up for trying Valery's method when I get my full disk setup it does sound good. One tip I use for deep sky flats is a white drum skin over the objective pointed at the sky or a lig...

Re: Flats from near full disk?

Hi I had another play with the image.
Shadows and highlights and added colour.
Not to bad, maybe a little over processed in places but does show some even detail.

Re: Flats from near full disk?

Hi Maurits Hope you don't mind but I had a play with your image above as I am interested in the same thing, removing variations in brightness. It sort of works but as Mark says you can't remove the bandpass variations. What I did was copy your image, then I saved two copies. One copy I used gaussian...

Re: 2 small spots

Hi nice image Paul
I just got a 5min break in the clouds and wanted to report some lovely detail in the spot near the edge of the sun
It has developed into a ring of very small spots with a bright centre in Ha light
good target for high res imaging

Re: Thursdays Hazy Start to the Day - 16th May

Hi Mark I totally get the transparency issue, not as much of a problem with a smaller object like a planet but the sun being so large can have many moving brightness across it that sometimes the staking software cannot cope with. Varying transparency is a major problem here in the Peak District as a...

Re: Thursdays Hazy Start to the Day - 16th May

Hi Peter It is and always has been an interesting argument this one. Many visual planetary observers preferred slightly hazy seeing because of the stable air that comes along with it, their reason for this is you record what is actually there and not fleeting glances of your imagination. This argume...

Re: Thursdays Hazy Start to the Day - 16th May

Very nice detailed images Mark Do you think that the haze actually works in our favor much like for planetary imaging and viewing? When it is hazy much more of the atmosphere is stable, this makes for better frame rates and although the contrast is a little lower it is much easier to get good focus....

Re: 13 May with Omega Ha

Thanks Alexandra for the positive comments. Your quite right about the house building in the UK. The reason we moved here was to get away from the light pollution. the interesting thing is on the plans for four houses the builders put in garages across the access to the fields behind and then they n...
