Error on Centering has grown significantly
Sorry for the confusion about what I am suggesting. Of course, any mount slew is absolute RA/Dec. So the point is to slew to the initial coordinates and take a picture. Then calculate the delta...

DesertSky: Thus the safest thing for SGP to do would be to avoid the sync. jmacon: I don't think this would work well at all. For sure it would not work for me.....the only alignment I do is within...

@Kinch, both the current method and the method I am proposing would get your scope pointing where it needs to be. The mount alignment helps get the initial slew closer to the target but is not...

I had to replace my HD which means a complete replacement of SGP. I had notifications working fine for the longest time. Now, not so much. I am using ATT as my cellphone service and Hotmail as my...

@DesertSky If SGP does not actually sync my mount then .....even though it has done the maths correctly (using your method) and puts the mount right on the position required.....will I not then have...

The chance that we will implement this "Delta slew" is pretty small. It's really just masking a problem with the mount or the model and that is where it should be addressed. At some point we have to...

Let’s suppose we have a mount with a very simple ASCOM driver. This Mount understands two commands: GoToCoordinates(RA, DEC) – the mount computes the difference between the actual coordinates and the...

It is 1 or 3 and may be different for different mounts. We don't care about the pointing model nor do we know if one exists. We sync at highly precise coordinates And slew to highly precise...

If you want to blame the mount for its imperfections - then you don't need any centering algorithm. Just do a slew and if it lands in the wrong place - blame the mount because the problem is the...

@Kinch, SGP is writing the fit headers so it can write the RA/Dec values from the plate solve rather than what the mount says. I don't know exactly how SGP does it now but the sync does not guarantee...

freestar8n: The SGP centering routine is fine in theory - but it makes the key assumptions that 1) syncing works in a particular way to readjust the coordinate system locally with one call - and many...

Ugh - this has nothing to do with ascom or sync behavior. The sync is working fine - it just has no benefit at all when there is inherent overshoot hitting a target. That is precisely why I and others...

I was caught up in using the mount model on my G11. But SGP's centering process is so much more sophisticated and precise (fast, single-digit pixel pointing accuracy anywhere in the sky). It's not...

DesertSky: Currently, SGP does:1. Slew to desired location; take a picture; do a plate solve2. Sync the mount to the plate solve location and again slew the mount to the desired location. For the...

I get a similar thing with my Schmidt Newt. The focus is very repeatable so I don't think it is the moonlite focuser slipping.

Kurious_George: I was caught up in using the mount model on my G11. As I understand this, when the pointing model was active on your G11 mount, you had problems with the centering. After disabling it,...

Correct. Pointing model is stored inside the G11 mount. ASCOM 6.1.1.2627 drivers are on my PC. After disabling (zeroing) the pointing model in the mount, SGP centering worked perfectly. Any errors in...

I agree as long as the focus is good it's not an issue...just a matter of curiosity.

@freestar8n seems to have a particular problem with centering that may or may not be widespread. I would be interested in knowing if others have that same issue, (and if so, they should speak up),...
