Thanks Roland. I think you have one of those at AP... 🙂

Of course! "Delay after correction."

Hah, no I just use really good telescopes and mounts. The GTX and Stowaway are excellent. The AP CDK would round it out for me.😄

There you go again embarrassing the rest of us mortals! Rolando

SCTs have their own challenges. Large apertures are more affected by poor seeing than small. On windless nights when humidity is high and the air is still and thick, you might be surprised in that

Get APCC Pro. I should have added that I used APPM models along with guiding to take those images. It is well worth the money. I took this with the Stowaway & 1100 combo completely unguided with APCC

Indeed. I am using an OAG. I get about 0.5 to 1.0 RMS while guiding with 5 sec exposures. Just wondering if I could do better. And yes, I know I shouldn’t just fret about the numbers as it the final

Make sure to use an off-axis guider and not a separate guide scope. OAG is the only way to guide with an F10 SCT. Rolando

Very nice – incredible images – I started following you on Astrobin 😊 . I have limited experience with the AP1100, just got it in April. I needed a replacement for my CGEM and since I am

Dang! Those are good. Rolando

I can speak to this with direct experience, prior to me installing the encoders. These were all taken with the 1100 and long guide exposures (5-10

I figured as much, but can it be done with SGP and PHD.

That is backwards. 🙂

Who has which backwards? --- Mike

Sorry, no.

I think you have that backwards. Rolando

Certainly, why not. The 1100 non-encoder mount can certainly be slow guided (bump guided with modeling) for hours at a time. Rolando

Curtis Do you have any pictures/movies of those L.A. airplanes transiting the Moon or Sun? I'm working on getting a light weight mount, tripod and scope setup so I can easily relocate for an ISS

Which is why I haven't tried 1 hr subs.

Possibly, but the real issue is, you need more than a few exposures to get a good signal-to-noise ratio. Signal increases directly with the number of exposures, while noise, being random, increases as
