Gert, It’s been many years now, but yes, I did that with my Mach1-GTO. I used a RN-270 serial to Bluetooth adapter (RN is Roving Networks). The SkySafari guys used to sell the identical

Roland Christen has published a polar alignment routine in the manual. It uses park positions and slews to reference stars to line up the mount. It is good for a first shot. Refinement can be done

Hello All, Is someone using the CPC3 (older generation AP mounts controller) with serial ports with a Bluetooth adapter to connect to Windows10 laptop (with Bluetooth built-in capability)

If the gain is about 1.14 electrons per ADU, it would work out just about right.

PEMPro works great. So does drift alignment if you don't have PEMPro. --- Mike

Use PEMPro. Aside from that, be sure to check your documentation. There are probably several methods of visual polar alignment, none of which involve Polaris, and there's probably a method of

I am a new owner of an AP1100 GTO. Though I have a RAPAS, due to my neighbor's tree growth, I am no longer able to see Polaris. Is there a method I can use to polar align without a clear view of

Focus drift is a problem of course. I focus at the beginning and in between each exposure. I have a thermometer nearby and have calibrated my focus knob and know pretty much where the knob needs to be

Liam purchased the Cmos camera to use with his RASA 8" scope. I have not had a chance to use it myself on my scopes. From what I've seen, it is quite sensitive and has higher resolution due to the

HI Rolando, One thing that occurred to me this morning is the issue of focus drift due to temperature changes. Did you change focusing because of temperature or left it as is for the 1 hour shot

Regarding the IMX571 it has a "75ke full welll" and 16 bit output. But 75k doesn't fit into 16 bits. How do you think they handle the extra 10k?

I always check out your images Roland, which are always fabulous. I hear from Liam that you've purchased a CMOS camera as well, an ASI1600 (I think mono). I've only used CMOS and am interested in

Swapping CPx control boxes will invalidate the PEM curves in both boxes. Just FYI... -Christopher Erickson Observatory engineer Waikoloa, HI 96738 www.summitkinetics.com

That is strictly up to what maximum error you don't want to exceed. In my case that was 0.3 arcseconds, which is set in the guider software as a Min Move setting of .02 seconds. Any guide star

When the nudge/minimal guiding gets activated is it based on exceeding a minimum movement or do you use some other parameter on which the guiding nudge occurs? The image is beautiful, especially with

Really beautiful on my retina macbook :) Brian -- Brian Brian Valente portfolio brianvalentephotography.com

Those are nicely done, Ron. All 3 are striking. Karen AP

Yes indeed, the smoke is making it all the way to the Atlantic. Rolando

Beautiful color images. Rolando

Wonderful. Transparency here has turned to crap. NO CLOUDS - but the sky is white... and my cloudwatcher says... DON'T BOTHER Is it the fires making it all the way here via the jetstream which is
