For me the biggest gain is that you can do the alignment quickly without having to bend down and such to use the polar scope.


Will Sharpcap account for Atmospheric Defraction? I live at about 18* north latitude.

At this latitude the polar scope is at a comfortable angle and contortions are not needed to view through it, but my PA will be about 3* off the actual NCP!

I try to make adjustments through the scope but drift aligning is still required.


No, it doesn't. Not at this time. At my latitude, 31-N, Sharpcap is more than sufficient, getting me closer to the pole than two iterations of ASPA. For you, you'll be limited, maybe 2' - 3'being about as close as you will get.

Hey Bob,

I can get that close with PHD2 drift but it takes a while. The NCP is only 18* above the horizon for me, well it should be anyways, atmospheric diffraction changes that by about 3* or so.

I think I will stick to my current method for now and drift align. I think I'll buy a new saddle instead.

Thanks

PoleMaster could account for the atmospheric refraction. I have been able to achieve polar alignment as close to 13 arcseconds to the NCP in just 5'minuted. There is no occasion now I won't start my session without the PoleMaster.

Polemaster does account for it (if you enter your latitude in the provided window).

Another similar utility freeware is EKOS polar alignment tool. Here is youtube video that shows how to polar align using the utility.

You can also check out their free Astrophotography tool. Most of the functions are similar to Sequence Generator Pro. You can setup sequence, focus, plate solve, telescope control etc.

I use polemaster and SGP but going to try this when I get a chance. Just as a backup.
