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.

So this means I was right? Oh, happy days!

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, ...

Re: Eclipse sequence - Dark, even, horizontal banding on the really short exposures
Hi Bill, I have photographed two total eclipses: Africa in 1973 and Mexico in 1991. I used Kodachrome slide film each time, so it is a lot slower than modern CMOS cameras. In Africa I used a 60mm f/11 refractor and in Mexico a SLR with a 200mm telephoto lens at f/5.6. In both cases my bracketed expo...

Re: eclipse settings
Hi Wayne, You list your location as "Bolton Laning" (sp?) Would that be the same as Bolton Landing? According to astrospheric.com you are just south of the path of totality. They say you will get 99.51% of the Sun obscured. What source are you using? I'm driving from Peekskill (40mi north ...

Re: M42 chronicles
Dave,
Yes, too short of an exposure brings its own set of problems. I think you are good with 3 stacks: 30s, 60s, and 120s. Then just concentrate on reducing noise by increasing Integration Time like 50x30s, 50x60s, and 50x120s.

Re: M42 chronicles
Hi Dave, Thanks for the great write-up! I have a question. Let me repeat your Lights exposure times. You wrote: Data: Lights 50x10s, 30x30s, 30x60s, 15x120s When I convert to Integration Time, I get: Data: Lights 500s, 900s, 1800s, 1800s IMO, you won't gain much faint nebula by moving up to 240s exp...
