Re: Exposure Starting Point
Hi Jerry, 5 to 10-minute subs are hurting you more than helping. Stars blow out. Sky pollution takes up a lot of your dynamic range. Satellites and aircraft damage a large percentage of frames. It's not worth it but there is a better way. Reduce your exposure. SharpCap's "Brain" helps with...

Re: Exposure Starting Point
The magnitude of a DSO, for example a galaxy, is the average of the bright and faint parts integrated over an ellipse. Who determines the size of the ellipse? Some governing body. Therefore, if today Galaxy X is said to be 20th magnitude, and then tomorrow the governing body says the ellipse is larg...

This definitely helps when centering the Sun:

Instead of a conventional compass, use your smartphone's compass. I believe it will give you readings relative to true north.

Re: Dark frame is completely dark on SV605cc
Just a guess but you have Black Level set to zero. (I say a 'guess' because I am assuming that Black Level is the same thing as Offset for your camera. Different manufacturers can't agree on a common name.)

Re: Beating seeing in Sharcap for an animation of the eclipse?
Your ability to "freeze" the atmosphere is a function of your exposure. The shorter the exposure the better. However, ultra-short exposures limit you to prominences and the chromosphere. You can employ stacking short bursts of frames every 30 seconds but this might be beyond SC's ability g...

Re: How to Estimate a Settings Range for Eclipse
Bill, Only use the Ha filter during partial phases. You'll have plenty of time to discover the proper exposure using the histogram. Remove the filter during Bailey's Beads and totality. Run through the following exposures: 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8, 1/4, 1/2, 1, 2, 4, 8, 4, ...
