I asked myself this question recently and came up with the following: * Setup of tripod, mount and OTA: all fine * Collimation: Almost there, but still learning * Polar alignment: pretty OK using SharpCap * Guiding: good enough most nights and much better since I switched to OAG * Backfocus: I'm pretty sure I have it nailed * Focussing: Great using ZWO EAF and APT * Post-processing: much better since I switched to PixInsight, but way behind a lot of people on here In the round, I would say my pictures are most impacted by my lack of post-processing skills rather than any of the other aspects. It's rarely the equipment that is the limiting factor. Your thoughts? |

Interesting question. I think that the processing skills are my nemesis. I'm so jealous of many other people here. Best Mike P.S. I'm watching Nadal-Djokovic right now. Great match! |

In terms of image depth it is light pollution at Bortle 6. Mitigation is to occasionally visit dark sky sites. In terms of resolution it is partly 'the seeing' but also - I have recently discovered - high frequency - 2-10Hz - jitter in the RA drive of the mount which causes persistent star shape elongation along the RA axis. Maybe up to a couple of arcsec peak to peak so it is a nuisance in short frame high resolution work at 0.5 arcsec/ pixel - but not so noticeable at lower resolution, when seeing is poor and on saturated stars.
