Star Alignment Performance

[jmasin1]

Hey all,

This is my first run at a complete bottoms-up process using PI.  I'm getting hung up on the Star Alignment.  It is SLOW SLOW SLOW.

I have (all fully calibrated and ready for align/stack)
15 x Ha (bin 1x1)
8 x R, G and B (bin 2x2)

Is it normal for this to take 40+ minutes?

Is there a better way or order to align these?  I've been trying to just align them all at once to a 1x1 reference frame.

Machine is a 3-core, Win7, 8G RAM.  Are there any PI options to improve performance?

many thanks!

Hi Jon,

Nice to see you here. It's me Peter in Reno from CN.

Are you running 64 bits?

My computer is:

Windows 7 64 bit
Asus Rampage IV Gene LGA2011 Motherboard
I7-3820 LGA2011 Quad Core CPU (3.6 GHz), no overclock
16GB DDR3 1866
1TB 6GB/s 7200RPM HDD
Sapphire HD7770 PCI 3.0 1GHz video card

I can align 30 subs in about 5 to 8 minutes.

My previous setup was:

Windows 7 32 bit
Asus P4C800 Deluxe Motherboard, 150MB/s SATA
P4 3GHz Hyperthread single core CPU
2GB RAM DDR400
1TB HDD connected to 150MB/s SATA on motherboard
AGP video card

30 subs alignment would take about 45 minutes.

Peter

do you see a lot of failed alignment attempts in the console? if not, i guess you have just hit the performance limits of your machine...
