Yes, the very faint streaks are caused by stars that moved with respect to the comet during that 1/2 hour period. The individual LRGB exposures were median combined which suppressed the star streaks

Roland, Nice picture of the comet. Are the light streaks at about a 45 degree angle stars? Eric

They keep getting better I like that the best of all I’ve seen thusfar “Corrected” by my iPhone

Thanks Ecki.

Brilliant Andrea and thanks so much for that “breadcrumb” trail, the option “save data for later use” escaped me, now back on track, Glad you were enjoying your new Mach2! Thanks again,

Tom, I can't check here but it is something I realized while imaging. First you connect to the NASA site and set the query as illustrated in the manual. Of course you need to select the right object

Nice image with lots of detail, Robert. Ecki

Andrea as a neophyte I would love to hear more of your prelim “tracking plan” workflow. Tom Fischer, INdy -- TJF MOBILE

Great image. APCC/ Horizons is not that complex to use in a field set up, in my opinion. I have been able to use it last week with my mach2, and it was the first time I powered up the mount :-) You do

A remarkable image indeed! Perhaps Roland can use his maths skills to calculate the width of the small outgassing core at the approx. distance of 100ish million miles distance from us. Should be

Simply amazing!!! Stuart Heggie http://www.stuartheggie.com/ -- Stuart http://www.astrofoto.ca/stuartheggie/

That is an amazing image! The most detailed i’ve seen! Marc Walk

Pierre is right. I updated the ZWO ASCOM driver when I loaded software on a new computer in May 2020 but it appears that ZWO, wisely, went back to ASCOM 6.4 a couple of weeks later. I will simply

Ah, terrific. I had read the meridian delay instructions quite carefully in the GTOCP4 and Keypad manuals, and how it was achieved internally and surmised that probably it was something overriding the

Whenever the keypad is set to EXT mode, it is advisable to always use the external app to control the mount, and that includes setting Meridian delay. In EXT you are initializing the mount via an

Any idea when the keypad revision will be available to the masses? 3-6 months? Thanks, in advance, Luke

Hi Ken, I’m pretty sure I know exactly what is wrong. The keypad performs the meridian delay by “fooling” the clock in the GTOCPx control box. The driver is probably undoing the

I shall check those things the next time I am out, thanks.

Meridian delay does not perform a meridian flip. Those are two different things. Normally the mount will continue to track past the meridian (overhead point) until you send a GoTo. Then it will flip
