PHD2 Rocks!
« on: 11:25:38, 03 November, 2014 »
The Dark Art that of Guiding and tracking with MaximDL Pro has always been an issue for me. Sporadic success with both Maxim & PHD either but I bit the bullet and tried out PHD2.

I must admit it's the Mutz Nutz so far ( barring any Gremlins that read this and inevitable head over to my observatory for a party )

Imaging at 5 min, 10 min subs with no jitter or drift at all.  So I decided to give it a gentle push and went for an 1800 sec sub of NGC1491 in Ha. Its only a test image and needs a lot more subs but just wanted to show how steady PHD2 held the frame for 1800s.

I tried PHD2 but couldn't really see a big difference with that and PHD.   It's a shame that you cannot dither in PHD alone.  This is why i had to set up Maxim.

Glad it working well for you,  no stopping you now

I don't know if there's so much performance difference but there's some clever features (eg calibration step calculation etc).
PHD and imaging software must talk to each other so that dithering software knows when imaging is done.

I also have MaximDL and had guiding issues so now use PHD2 in conjunction with SGPro which has a brilliant dithering routine and with the plate solving is perfect. I still use Maxim for alignment and stacking.

Do you guide in declination?  This is the one that sometimes causes me problems.

Yep, I like PHD2 also, not sure what is different but it does seem to work a lot better, and just seems more intuitive to use

I'm using it for the first time tonight. Loving it so far. I use BackyardEOS and it has the connection so I can dither. Haven't done it yet but I plan on it. I'm using it with a Lodestar and it calibrated first time with the default settings. Seems to be working great but I'll have to pull the images off so I can see them larger to really tell. They look great the stars are perfect on the notebook. My mount tracks well and I didn't expect much but there is a difference for sure.

It evens out background (systemic) pattern noise, essential for DSLRs but not so important for cooled CCD cameras because they usually have very low noise anyway. Certainly my Sony-chipped 490EX doesn't seem to benefit, but the Canon 70D does as it reduces the colour 'mottle'. Maybe Kodak sensors would benefit more that Sony.
