Large Filament | 150mm & Quark | 6562.8A | July 24th 2018
Hey all,
Been a while, it's currently raining. It's been days, if not nearly 2 weeks, since I've been able to do much other than dodge rain going in and out for work. Of course, the first day I wake up to a cloudy, but not raining morning, with potential sucker holes to shoot through. I have a new-to-me refractor to try, picked up a 150mm F8 doublet achromat for dirt cheap here on the forum. Shows a ton of CA at night with visual in visible spectrum. But it's fantastic in ultra-narrowband. Today was my first use with it and I did both visual & imaged for about 2 minutes before the rain started. Visually it was bright, contrasty, looked great. Imaging wise, I could notably feel the new limits of seeing on 5040mm effective focal length, but the seeing supported me looking at some surface spicules and the big filament currently present. There were two faint prominences on the limb, which I could make out fine, but they were not worth imaging at the time, so I pointed it at the filament. Not my norm, as I usually am all about prominences more than anything when there's not a sunspot around.
Equipment:
Celestron (6 inch) 150mm F8 Refractor + 80mm, 80mm & 50mm extensions with Baader UV/IR block filter (ERF) with GSO Focuser (upgrade from stock)
Quark Chromosphere
ZWO Tilt Adapter (wasn't needed, but I always have it on)
ZWO ASI174MM Camera
SharpCap (acquisition) | Autostakkert!2 (calibrate, stack) | IMPPG (deconvolution) | CS5.1 (final processign) | Best 351 out of 3,000 Frames
Astrobin:
Very best,

Looks great! My seeing has been just the worst recently, and the 110F temps don't help either - Quark won't stay on band. Why is astronomical equipment painted black?!? Everything is painfully hot to touch and the bubble level on the Mach1 seems to have boiled off. Time to drop back to the Lunt for a spell.

Dunno why everything is black, I guess most of it is intended for night use.
Doesn't bother me, either way. I generally only spend a few minutes in the sun. If I were doing an extended couple-hour-session, I'd just throw my reflective solar cover on there (big enough to cover a C14 & mount, I use it all the time when the mount's not in use).
Very best,

Interesting comment re the Quark...here in Australia we regularly get temperatures in the 40 deg C....
I could not get confirmation from Daystar that the quark would function in elevated temperatures......

Hi Marty...
An excellent capture of the filament...well done!!!
I use the same Celestron OTA as my donor scope for the Lunt mod...they do work well in the narrow bands for solar. I see you had to put a lot of spacers in tho the the Quark to focus...took the mages to get the spacing figured out when I was testing out a friends Quark

Super stuff - really detailed & dynamic image - must be pleased with its debut!
