blinky

cool, thats pretty much my normal method - except this time I removed the 2ndry for cleaning, its never been cleaned in about 15 years!

I've collimated with my laser a Hotech and was wondering how I use this other piece of equipment? It's like a collicap but it's reflective inside, do I adjust the primary or secondary? I can see three reflections, and assume they should all be lined up, but which mirror do I adjust foe this?

Sorted! Cr@p USB cable

Anybody got any ideas? For some reason, if PHD2 (Latest version) is running and guiding, it hangs the main camera in SGPro... If I have everything connected in PHD2 and click download in SGPro it works, start guiding and it just hangs, then eventually PHD2 says it cant connect to the camera. Im sure Im up to date with drivers for Ascom etc

It should be 110mm if I remember correctly

I dont see the 45% off voucher 😞

It daened on me this morning, I had the same timeouts with an eq6 and one of FLO's eqmod cables, that mount is on a pier in the observatiy and I went back to an ancient shoestring astro adapter and it has zero issues. So I've tried swapping everything, mount, cables, power supplies, laptops and have nothing connected other than the cable going directly to the laptop.

See my wanted ad - Im trying to figure out why I keep getting timeouts with my HEQ5 Pro... Im using an FTDI Cable, have also tried one of FLO's cables in the past with the same error. Ive swapped power supplies, cables, ports and laptops all have the same timeouts happening in EQMod (Have also tried an older version of EQMod). As a final step, I thought I would see if the motor controller board needed updating, I downloaded the app from Skywatchers website and it says I currently have version 2.4.01, which is strange as the latest version on the website seems to be version 2.04, as I getting confused? Why is my current version higher than that on the website ?

Pixinsight does have a LinLRGB tool in the utilities section, never used it before but its there....

Thanks for all the replies folks - it seems its more complicated than I at first thought!

I agree with that, but this was defiantly more focussed around the 'in theory' rather than what we actually would experience

My argument is there is a finite amount of light being emitted, if you open your curtains, that light escapes and lights up the road outside, so there must be less light inside. Another analogy, you shing a light on a wall from 6 feet and from 20 feet, 20 feet will be dimmer 'cos the light has spread out further

That is exactly my thoughts!

Argument sounds so much better but in reality this is just a discussion that myself and my mate are having with my wife and my Astrophysics qualified daughter. It goes like this.... You turn the light on in your bedroom in the middle of the night, i.e. its pitch dark outside and your curtains are shut, now if you open your curtains, light floods outside and illuminates the street and people can now see you have turned the light on. So.... the argument - when you open the curtains, does it get darker in your bedroom? Me and my mate say yes - although its an in theory and in practice we don't think its probably even measurable but... some of the light that was lighting up the bedroom, now lights up the street outside, so surely the bedroom must have got imperceptibly darker right? The light coming out that single lightbulb in the ceiling (the 'big light' as we call the celling light in our house) doesn't get brighter 'cos you opened a curtain, so the room must get darker as the same amount of light is spread out... My wife says nonsense (but by her own admission knows nowt about physics) - my daughter says probably nonsense but she would need to do calculations based on the colour or something of the curtains since they would be absorbing the light until they were opened, then they wont be absorbing light so that light would escape. Thoughts from the SGL collective?

I'm looking at the pixma Pro 200, so that's good to hear the 100 is good
