I have been working with a lot of new equipment at the same time I am learning SGP, but equipment and weather generally cooperated last night. Unfortunately I am having trouble with my focuser, so I was only able to focus at the start of the imaging - and I just left it at that setting for the 3 hours of this image.
This is a view of the IC410 tadpoles with Edge11 on cge-pro at f/10, with Atik 383L+ (8300) ccd and 3nm Ha. 12x15m exposures calibrated and stacked in my own code - then only levels applied in Photoshop - no other processing or cropping. Original scale was 0.4" per pixel - reduced here to 1.6". Original fwhm was in the low 2’s arc-sec.
This test confirmed that everything in SGP works fine with MetaGuide using the MG dithering provided by SGP. SGP does not control the amount of dithering - you have to do that by specifying it in arc-seconds in MG. Also, SGP does not monitor the guide error to tell when the guiding has settled after dithering. But if you just enter a delay between frames in SGP, the delay will happen just after the dither command - which is ideal. So the exposure ends, the image is downloaded, the dither happens - and then the delay. Just enable MG dithering in SGP and set an inter-frame delay (in this case 10 seconds) - and it all works.
I am guiding with OAG and the dither radius is 15" - so it recovers quickly from the dither move. There is no need to stop guiding or anything - dithering just happens and the star is quickly pulled back in.
I am hoping to do more automated sessions with focusing and meridian flip - but everything worked ok here for this fairly new user to SGP with a new OTA.
