Re: Sun filament

Wow John,
Massive filament and impressive results for a single shot with the 550D. The Lunt 100 seems like a real performer.

Very nice Hans! How do you like the ZWO? What capture software are you using?

Re: FLIR Grasshopper 3

Is anybody using the QHY5III174M? It runs at 138fps full resolution which is nearly the rating on the Grasshopper 3 for a considerably smaller investment. It does not have a separate external power jack or the built in memory buffer. I'm thinking the buffer may be overkill for my situation given the...

Re: FLIR Grasshopper 3

Hi Bart, Here's the cable only from FLIR's website as well. https://www.ptgrey.com/1-meter-circular-8-pin-pre-wired-gpio-hirose-connector Seems the pin count varies widely on the circular hirose connectors. I didn't find anything better/cheaper. Unless you want to make your own. Then you can buy a b...

Re: FLIR Grasshopper 3

Hi Mark,
Thanks for weighing in. I suspected there would be an external power advantage. I see some power supply options on eBay that would work quite nicely.

Re: FLIR Grasshopper 3

Thanks Robert and Bart for the insights. Still leaning towards the Grasshopper 3. I remain curious about the differences compared to the ZWO. I don’t see that the ZWO has any buffer memory which I suspect may play into the slower FPS. I’ve been watching the classifieds for a nice used one but it app...

FLIR Grasshopper 3

I am starting to narrow down the imaging end of my solar set up. In perusing the various resources (posts, tutorials, vendor sites, etc.) I'm finding that the Point Grey Grasshopper 3 and the ZWO ASI174MM are both very well liked by the solar imaging community. In looking at the Grasshopper (now FLI...

Hi Bob and Raf, Thanks for weighing in on the fluorite question. I'm curious about the force/process that would result in the catastrophically high thermal expansion of the fluorite. I'm hoping Bob is willing to weigh in further still. :? It would seem it is only subject to ambient temperatures sinc...

Solar Grab Bag

This week I had the good fortune of running into a solar grab bag of sorts. While still focused on equipping the APQ for high quality H-alpha I ran into a very interesting pre-owned bundle of gear containing at least one of the components needed - the full aperture (130mm) mounted ERF. But there was...

Re: H-alpha Zeiss APQ 130

Hi Alexandra, Thank you for the reply and advice. I vaguely recall Solarscope (hailing from the Isle of Man) as being at the apex of consumer etalons, a spot they appear to still occupy. Unfortunately, it is an investment I'm not yet ready to make. I'm thinking I may opt for a rear mounted option at...

H-alpha Zeiss APQ 130

Way back in 2007 while attending NEAF, I had the pleasure of looking through a Zeus APQ 130 that was set-up with a Coronado 90mm etalon. The view was unforgettable. At the time I owned a Solarmax 40 so I had some perspective on the h-alpha solar observing experience. Additionally, there were other c...
