Guide to fixing tilt and spacing with objective analysis- Word Document Version


Chris White
 

Mike Hambrick asked if it would be possible to create a word document version of the writing I have done on fixing tilt and spacing with objective analysis.  The threads here, on CN and Astrobin that I started have gotten a little unwieldy so I've compiled the important information here in one document. 

There are five main parts to this guide.  I'm happy to answer any questions, or if something is not clear please let me know. 

See attached.

I hope you find this helpful. 


 

Thanks Chris! a great resource

Thanks Chris for this and all your help to so many in the astro community on this topic. This beats re-reading all the posts on CN and Astrobin. I replaced my TEC FRC with the TEC FF (no longer available from TEC), adjusted tilt with the octopi and now have round stars in all corners with my QHY600M. Only took me a year to get here!

Yes,

Thanks Chris for the work.  Last night I FINALLY dialed in my Newtonian.   It is not dialed in like you or Linwood's presentations, but is good enough for me at this point.  No less than five times I considered dismantling everything and selling the parts.  Building a simple Newtonian astrograph was very hard for me.   I finally have reasonable stars across only an APS-C frame.  The scope is now a keeper.  I find NINA's aberration inspection to be pretty good for curvature but less reliable for tilt.  I have a hard time getting stable readings.   Paul is correct it takes a long long time to get everything aligned.   I think that once you do it you get the experience to go forward and do it again a lot faster.

You're welcome. My main goal with all of this is to share what I have learned through many hours of testing, so that people have a path forward to improve their stars. Happy it could be useful.
