PREVIEW: New Tutorial on calculating your Image Scale

Brian Valente #67026 开云体育 This isn’t yet published, but I wanted to pass this along to this special group of folks and see if there’s any feedback ? It’s Part 1 of Practical PEC for your Gemini ? It was supposed to be a short ‘here’s how to calc your image scale’ but it ended up 18 minutes long ? ? ? Thanks ? Brian ? Brian Valente Losmandy Astronomical ? Losmandy.com Tutorials and vids at ?
Jim Waters #67034 Good tutorial and information but I am confused.? Shouldn't you enter your auto-guider information and not your imaging scope if you intend to use PEMPro?
Brian Valente Member Profile All Messages By This Member #67035 Great question -? I covered this briefly, but to clarify, you really want to use your imaging scope. Recording your PEC data has nothing to do with guiding.? toggle quoted message Show quoted text On Mon, Jul 6, 2020 at 10:25 AM Jim Waters <jimwaters@...> wrote: Good tutorial and information but I am confused.?

Jamie Amendolagine All Messages By This Member #67038 Great video! The start and finish are awesome!? Very informative, I don't know if you need to add this but you can install? locally, on your imaging computer and it will always be there as long as you're imaging computer is. That's how mine is setup. I've found that it runs faster when it's installed locally, and is of course more reliable when I'm imaging.? Jamie

Jim Waters #67042 I need to clarify.? Yes; you need to use your imaging scope.? I am not taking about PHD2 guiding.? I used my auto-guider (QHY-5L-II) for PEMPro PEC training and my 630mm scope last week.? Are you saying I should use my imaging camera (ASI2600MC Pro)?? Both have?3.75um pixels.
Brian Valente Member Profile All Messages By This Member #67043 Hi JIm In your case, probably either is fine The general recommendation is that you use your existing imaging setup so you can avoid the inconvenience of reconfiguring your telescope setup, etc. the imaging camera?+ scope is preferable because it is generally more secure to the mount (i.e., no rings or other source of possible error) and usually has a finer imaging scale, both of which improve the data you collect if you want to send your data i'm happy to take a look at it hth toggle quoted message Show quoted text On Mon, Jul 6, 2020 at 7:21 PM Jim Waters <jimwaters@...> wrote: I need to clarify.?

Ray Gralak All Messages By This Member #67044 Another reason you want to use the main scope/camera is that the larger sensor area of the main camera will usually allow for more drift before the star being tracked will fall off the sensor. -Ray Gralak Author of APCC (Astro-Physics Command Center): Author of PEMPro V3: Author of Astro-Physics V2 ASCOM Driver: toggle quoted message Show quoted text -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Brian Valente Sent: Monday, July 6, 2020 7:27 PM To: [email protected] Subject: Re: [Losmandy_users_io] PREVIEW: New Tutorial on calculating your Image Scale Hi JIm In your case, probably either is fine The general recommendation is that you use your existing imaging setup so you can avoid the inconvenience of reconfiguring your telescope setup, etc. the imaging camera + scope is preferable because it is generally more secure to the mount (i.e., no rings or other source of possible error) and usually has a finer imaging scale, both of which improve the data you collect if you want to send your data i'm happy to take a look at it hth On Mon, Jul 6, 2020 at 7:21 PM Jim Waters <jimwaters@...> wrote: I need to clarify.
