Please Help - Noisy .fits image

[Forum_2017]

Hi, when I capture images with Sequence Generator Pro the preview on high stretch looks like the image below (really smooth)

However when I open them in AstroArt they look like this (really noisy)

I have applied a similar stretch to both (I think but I'm no expert!), I was hoping someone here might be able to explain why the fits file preview in SGPro is so much smoother than when viewed in Astroart. Am I doing something wrong?

Many Thanks

Alan

Hi, may you check again that this the same image? (the sgp one has bright bands on both sides). By the way, if this is a large image, and you are visualizing it with an extreme "zoom out" ratio, then you can solve enabling the option "Zoom with anti alias" in Preferences.

Hi Fabio,

That was it, no anti-alias! Thank you so much for such a quick response.

By the way, I think your software is superb, very fast and intuitive and I design software myself so I'm very picky. It's well worth the small cost.

Keep up the great work.

Kind regards

Alan
