| @Michael Ring That is very kind. My raw files are 1TB - so I will need to find a bigger USB stick! I have started the processing and will see how I go. Currently it is taking my machine around 1.5hours to run WBPP on 25 2400MC frames in high quality. My machines PI benchmark is around 4000 - even with 64GB of memory [only 4 cores]. Seriously thinking of a new MacBook Pro M3 with 64GB/16 cores. But I wouldn't be going on holiday! |

Brian Boyle: In my opinion (if you're not too attached to macOS) the best choice is to build yourself a PC. With a budget of around 2000 € (the price you get a MacBook Pro M3 in europe) you could make a machine that is very powerful and upgradable through the time. Just do a bit of research and you should get a great idea of what you can buy. I've recently built one for a friend and with 1500 € he got a Ryzen 9 7900X (12 cores), 32GB of RAM, and 2TB of fast storage. In addition he bought a NVIDIA GPU to accelerate the AI plugins for PixInsight. With that system he can run WBPP in 25 min for 75 2400MC subs. Daniele |

| Thanks, Daniele. Yes I suspect that is the sensible route. But it is probably beyond my technical expertise [at least currently]. I might have to do some research. CS Brian |

Just did a quick test, 15 minutes for 36 frames of IMX571 (26MPx) with 1x drizzle and highest quality, that's quite a difference compared to your 4 core system. USB Sticks and SSD drives are not that expensive anymore, perhaps it is worth a thought for you to go that way.... Michael |

Brian Boyle: As I struggle to catch up, intellectually, with the minimal required specifications for each field I am curious to know what the expectation is for limiting stellar magnitude in these fields after the fields are processed for background, astrometric/coordinate, and cosmetic standards prior too or after insertion into the final mosaic. I'm sure this has been stated in at least some manner here before, but it may be lost in the body of text throughout these threads. The hours of integration stated for B1-B4 points to this standard at least roughly. |

Brian Boyle: To second @Daniele Borsari , I think building is the way to go. But I should not pile on! There have been some price fluctuations for the commodities, but Danielle's quote is right in line with the cost of my build 5 years ago and expected. If curious, I recommend finding some PC magazine articles for building gaming rigs. Also YouTube videos for how-too. Everything is plug and play. Get a rather older, cheaper NVIDIA graphics card. PI is not too demanding for parallel processing AI functions. Same with CPU version. If you still want to go on holiday, do not buy the latest generation CPU! Big cost penalty for incremental increase in performance. If you go that route, be aware you will need to deal with the change in OS environment. Benefits include that any homebuilt will be vastly more capable than a commercially pre-built at the same cost. You become the expert on when and what to do to upgrade in years down the road. Alternative is to find a local kid who games, tell him what you want and pay him/her to build it. |
