Thoughts about a C14 Edge on a Mach-1 for just visual poking around, NO imaging? Same for a 160EDF, for just visual puttering? Thanks Mike J. Shade Mike J. Shade Photography: mshadephotography.com In

If one were to ship a 1600, first generation back to AP, would you folks be able to do an absolute encoder install on it? Time needed for that? Moving from SE Arizona to very rural and dark NM. Observ

Hi Mike, 55 degrees elevation is more than good enough for measuring periodic error. If you want to minimize seeing issues, try waiting until early morning, a couple of hours before dawn, and start co

Have a few questions on best practices for PemPro data gathering. 1600GTO, early model (just had bearings replaced in RA/DEC gear boxes), Planewave CDK 17/unbinned image scale .631"/pixel/permanent se

In SE Arizona at 5000' elevation, where we can have a pretty good heat cycle from day to night, I check and adjust polar alignment if needed once a year. If there are any adjustments needed, they are

A couple of questions...in PemPro, what would a damaged first generation 1600GTO RA worm look like, in the data? Is there a way to tell? What about tracking? If it is suspected that the worm is damage

Ah, OK, not a big user of PI but the chart helps. Thanks... Mike J. Shade Mike J. Shade Photography: mshadephotography.com In War: Resolution In Defeat: Defiance In Victory: Magnanimity In Peace: Good

The value of .5 is stated as round, I am curious if .05 is what people mean. According the Maxim's help, a value of .1 means that the star is longer in one axis by 10%, so a value of .5 would be 50%.

To add, data from 3M "Respiratory Protection for Airborne Exposures to Biohazards, Technical Data Bulletin Release 5, June 2020 #174" and "Respirators and Surgical Masks: A Comparison Technical Bullet

So the question becomes, how does one enter into the keypad custom RA/DEC to go to an object not in the database in the keypad? I know how to procedurally do it, but if there is a discrepancy in the v

Trusty 1200GTO, with the latest chip. In observatory, polar aligned. Will have it slew to say Arcturus, puts it near center of the field. Says the RA is 14:15:40, Dec +19:10:56. Fine. Will go to the R

Yea, drop it there are people here with slow connections and don't need 24mb of video. Mike J. Shade Mike J. Shade Photography: mshadephotography.com In War: Resolution In Defeat: Defiance In Victory:

I have seen about every geometric shape possible with out of focus stars during a FocusMax run with the 17", worse when the seeing is poor. According to my seeing monitor, I tend to run around 2" on a

What do the stars look like when you take the system out of focus like for a focus run? Are they nice concentric circles or do they go from round to oval to any one of a number of shapes? This can be

Consistent problems suggest hardware problems, polar alignment, PEC curve issues, flexure, poor guiding parameters, this sort of thing in that they impact everything consistently. Unusual or rare prob

I have some questions about mechanical adjustments on a first generation 1600GTO. I am having issues with the RA axis, specifically tracking. There seems a lot of periodic error that is hard to guide

Prior to a PEC curve, you might want to remesh the gears...then run your curve. Mike J. Shade Mike J. Shade Photography: mshadephotography.com In War: Resolution In Defeat: Defiance In Victory: Magnan

Good to see feedback. Not sure what your mount/imaging system is but a good test might be to see what the mount does unguided for a worm cycle...with PEC on and PEC off (you have a good PEC curve righ
