no one ever seems to think seeing conditions are ever a variable ;)

you can select log portions in PEMPro Log Viewer

Gaston (the CEO of innovations foresight) is a brilliant guy and i'm currently working with him on his wavefront analysis software for colimation etc. he's got a lot of great ideas, very advanced

I had another think on this and I see what you are getting at. At the beginning and ends of the session in question, PEC was off. In the middle it was on and recently trained. However, when I load the

Thanks Eric, it had not occurred to me that PEC could not remove anything that was not exactly in phase with the worm rotation period. But of course that makes sense now that I think of it since the

I love sitting in the back of the class room with discussions like this. I'm beginning to confirm things I thought I was seeing correctly, but wasn't sure. I hope to be more observant of my RMS error

Hey Arun, I resemble that remark... LOL! I tried really hard for a month with 2 different OAG's when starting out. For all the same reason's of sampling the same picture the telescope was seeing. But

Paul, I reviewed your PHD2 log and here are my findings. At the beginning and end of the log, when you stated PEC is off, the main frequency components are 1x, 2x and 3.15x. In the middle of the log,

Hi Bill, Like I was explaining to someone the other day, your mount does need some actual run in time to smooth out the gearing. The gear pattern in these mounts is what's known as a bull gear. They

I chose a ZWO 178mc for a guide camera + planetary. I normally use an OAG and figured the bigger sensor would help with finding stars at long focal lengths. I also chose an OAG with a large pickoff

Bill here's the thread i was thinking of /g/Losmandy_users/topic/77978914#68733

Group, I received my new G811G yesterday. Assembly was straightforward and I had no trouble attaching the motors. To my dismay, when moving using the HC, the RA motor was quite loud. The Dec motor was

Thanks for the feedback Brian. ONAG is a bit pricey for my tastes, and is probably overkill for the intermediate range setups I use. Eager to see how multi-star might improve guiding with my guide

I am going to put a 2X barlow in front of the SX guide camera and use binning on my SX 814. I will then see if that has an improvement. I am sure it will. I have used the 2x Barlow in the past when I

My guide camera is still functioning only intermittently, but on the one night I was able to try multi-star, my typical guiding around .5" -.7" RMS went down to as low as about .3"!

Replying to my self..... I had a look at the other stored PHD2 logs and while I find the same worm, worm x2 and bearing signals, they are not as significant and guiding was more precise. That leaves

Your included image looks perfectly understandable to me. It shows RA errors at three important frequencies.... worm, worm X2 and worm bearing. It also matches the frequency domain plot I get in

After all this discussion, I downloaded PHD2 Guiding 2.6.9dev2 with the multi-star option tonight to give it a try. After running the installer app, I opened and found my old profiles and settings

Hi John images that the guide ware would use for improved guiding. okay i see what you're saying there. Larger sensor size isn't important and doesn't really buy you anything for 99% of guiding. once
