Re: unequal brightness in image

That's great news, Joe! Now only if we could get some clear nights. I think you will be in good shape if you wait for objects to get higher above the horizon. Your Hyperstar is a "light sponge" so you should be able to get decent results in an hour. Try the brighter objects first, like M57 and M27, ...

Re: M63 - Sunflower galaxy

Very nice detail. Great guiding!

EDIT: Now I see why the great guiding: short exposures.

Re: CzeV627 Delta Scuti Variable Star

Let me know if I can help, Bruce.

I finally got my wish for a drought following years of incessant rain. Now the days are beautiful but the nights are afflicted with high altitude thin clouds, enough to damage any attempt at imaging.

Re: occulation

John, I searched the Internet for "Gstar-ex" and "occultation". Very few results. Basically people using the camera to record a star passing behind the Moon. Then I searched for "occultation bar". Again just a few results. Basically people adding a thin strip of metal in the focal plane of an eyepie...

Re: occulation

Hi John,

When you say "my Gstar-ex camera's occultations routine has collapsed" what does that mean? I have a software background so the word "routine" refers to a program component but the word "collapsed" doesn't make sense in this context.

Re: unequal brightness in image

Joe, Are you sure you are Bortle 8? If you are 8 miles north of the GWB then that puts you in Alpine, NJ. Light pollution maps put you at Bortle 6-7. Anyhow, light domes are everywhere. You could be a rancher in the middle of Montana and your neighbor who lives 10 miles away turns on his barn's floo...

Re: occulation

Let's give John a chance to run experiments. Like John says, an "occultation bar" is the best solution because it prevents the intense photon flux of the star from striking the sensor, but I am skeptical that an "anti-ROI" function is that helpful. After all, the thing that causes a bright star to b...

Re: occulation

John, I'm always open to new ideas, so let me ask, have you tried testing your theory? For example, take 10 frames of Sirius, and then before stacking, edit each frame and erase several of the saturated pixels at the star's center? After doing that what does the stacked image look like? Does it impr...
