George - you are consistent! That is what your proposed (and we are planning to do) with the 1600 at obstech :) Brian-- Brian Brian Valente portfolio brianvalentephotography.com

Brian, If you want to take accuracy up a notch, try the RA Corrective Method. It will improve your imaging in the area from 45 degrees to the zenith…where we usually image.

yes- I mention/ask about PE correction in my opening email on the topic. It was the modeling part I was missing. Thanks for confirming and the additional information.

Thank you, George. I'll try that. In the meantime, it's a clear, sunny day. I did a go-to to the Moon. In a 30 mm eyepiece (33x) it appeared at the edge of the field. Once I centered the Moon and

Check and update your Periodic error with PEMPro. The 1100 mount can easily do 5 minutes unguided to sub-arc sec accuracy. You will need a model of course, since the stars in various parts of the sky

well, let's just stick that we think alike and hold-off on the great part....at least for a few more years :-)

good to hear great minds think alike, or at least, my feeble mind thinks like other great minds! Brian -- Brian Brian Valente portfolio brianvalentephotography.com

Actually, the same as you just described. I started out using Polemaster and now use SharpCap. So, "excellent" per the definition and limits set by SharpCap.

Bruce - how do you polar align? i ask because i used to think i had excellent polar alignment via polemaster, until i realized how "accurate" it was (and i use that term loosely). Now that i polar

Thanks all for the additional feedback. I'll see how far I can go next time I put the hyperstar on. I have excellent polar alignment in my permanent observatory and other than sky conditions, I

Thanks, Joe. I have excellent polar alignment in my permanent observatory. I'll give it a go and see how far I can push the exposure time.

Curtis, Loosen the clutches; tell the mount to go to Park 3; wait until the motors stop running; put the mount in Park 3 with your hands and tighten the clutches. You’ll be fine. PS.

Date and time in the keypad are correct.

mike do you have the absolute encoders on that mount? and just curious if you're using APPC/APPM on that unguided Brian -- Brian Brian Valente portfolio brianvalentephotography.com

I can do 5 minutes unguidedwith my 1600GTO and Planewave 17 at 2935mm fl and .63"/pixel. Permanentsetup, very good drift polar alignment. Depends on other factors than themount. Mike J. Shade:

I usually do 90 seconds with my C14 Hyperstar & 1100 unguided for narrowband if it's a particularly faint DSO then 120 seconds. But there will be a few subs discarded usually due to mirror flop. I

Thanks for the comments, Bob Denny pointed me to the settings and the lengthy help in ACP but the bottom line is there is an flip ACP setting under telescope to set a fudge factor of say 40 minutes,

Bruce, I always shot my RASA unguided on my 1100. That’s basically what you’re hyperstar is. You’re probably only shooting 60-90 second images with that. I just aligned with my RAPAS and

ok- thanks for your input

Hi guys! Don’t want to be too much of a nag, but any news on Mach2 shipment? The website still says shipping in January 2020 and, well, this is the last day of January. I have really been hoping to
