Re: RS-232 port damaged
In the picture 4 side RS232 jack it looks like there may be corrosion on contacts inside the jack. This is a very common problem with these jacks, especially if there has been any moisture exposure.

Re: Elongated Stars
In L5.2 adjustments were larger, yet version produces round stars. Still, given oval stars the standard distribution minimally requires a 3x3 grid of pixels.? From the center of this the minor axis

Brian, While my losmandy mount is not on my permanent pier, I do leave it out for long durations. First my permanent pier mount. I go years without touching my polar alignment once a scope is mounted

Re: Elongated Stars
Elongation is in RA direction. Yep, I agree. Better data is better. But increasing DEC min move will make for round stars at the expense of more convolution in the direction of DEC. --

Re: Elongated Stars
That's my usual assumption -- 0.2 RMS means I did something wrong:) I'm certain that it was a true value though as the images showed way more detail than the night before or after, and I did not

Re: Elongated Stars
So was the elongation in RA or DEC direction? I would try to get as much of the elongation out during capture as I can. It doesn't just distort the star shape, but it also smears extended objects in

Re: RS-232 port damaged
David is the expert! To me that looks like some moisture got in through or around the RS232 jack that caused the white stain around it on the PCB.

It¡¯s not the socket that will be the problem, it will be an integrated circuit on the printed circuit board. Sent: 04 June 2024 16:37 To: [email protected] Subject: Re: [Losmandy_users_io]
