Pages: 1 Aquarist professor emeritus Reged: 08/27/12 Loc: Illinois Seeing conditions with Daystar filters?       #5561212 - 12/08/12 05:06 PM Edit   Reply   Quote Quick Reply   How important are seeing conditions for solar observing with Daystar filters on a refractor (TOA 150)? Will observing from my Technical Innovations dome be a problem? Is there any season or time of day that is likely to be better or worse (suburban backyard observatory)? Thanks in advance.

It is all about the local seeing, when I had a Home Dome mid morning was best before surface heating or wind picks up. In winter the jet stream kills a lot of the clear days. I was in Michigan at the time and you have the lake effect to boot, looks like a gorgeous day to start and clouds form out of thin air. Every once in awhile it would be the perfect day.

In fact, you most likely want to step it down anyway since Daystars are optimal at f/30. Which at f/7 native you want at least a 4X barlow or Powermate.

[Re: drksky]       #5566588 - 12/11/12 09:15 PM Edit   Reply   Quote Quick Reply   In my experience Solar is no different than planets. With my Daystar and SolarSpecturm filters I never saw an advantage to stopping down my AP130. If seeing is bad then the see is just bad and nothing helps. If seeing is good you want as large a scope as possible. When I lived by Lake Michigan local seeing was rarely an issue (morning afternoon or evening were usually good) as long as it was clear! However if the jet stream was within 200miles seeing was usually poor. Post Extras:       AstroPaolo professor emeritus Reged: 01/30/08 Re: Seeing conditions with Daystar filters?

It is anoying prepare all the telescopes/filter and discover the seeing is worst and cannot make anything. Post Extras:       Pages: 1
