Re: New Skywatcher Solarquest mount

Agena Astro have asked Skywatcher USA if they will be selling it, and told me the answer was, no they won't.

New Skywatcher Solarquest mount

Has anyone tried the new Skywatcher Solarquest mount, which claims to find and track the sun automatically? If it works as advertised its inbuilt solar auto-guiding/tracking could make it a useful mount for lightweight solar setups (stated load capacity of 4kgs). Link here to APM telescope's webpage...

Re: What camera do you use?

Has anyone tried the ASI178mm (2.4um pixels) for a short focal length Ha scope? I've been trying my ASI174mmm on a solarmax II 60 and its not working well. I think the pixels are I think just too big for decent resolution at that f/6.7 ratio,. and I;m looking for small pixel option, preferably under...

Maksutov Newtonian with Quark

Hi All, Just after people's thoughts on my idea of perhaps trying my 152mm f/4.8 Explore Scientific Comet Hunter Mak-Newt with my Chromosphere Quark (a standard Quark, not a Combo Quark). Currently the largest aperture scope I have used my Quark on is my cheapie Synta 102mm Achromat. Obviously I'd n...

Re: Ca-K options:

Hi Michael, Daystar are advertising the imminent release of a new Quark filter that works in the Ca-H line band rather than the Ca-K line band. I know nothing about that Ca-H band but that might be worth taking a look at. Daystar suggests that the Ca-H band works better for visual observation by old...

Re: Sunshine, but probably the last

Thanks folks :) For the flat: I take my video with the Quark, then pop a piece of cling film over the front of the scope and take 500 frames with cling film (not changing anything). I then create the master flat in Autostakkert2 with the cling film video, then process the original with 'load master...

Re: Sunshine, but probably the last

Lovely images thanks Alexandra. How do you do your flats for the Quark images? At the moment (Quark and ASI174MM camera on 102mm f 6.5 achromat) I use a short defocused centre of disk capture (about 1 cm of focuser travel away from focused) and then build the flat in Autostakkert 2. I sometimes stac...

Re: Solar Flare timelapse animated gif. Quark

Thanks Mark, Stu. I only saw the plasma plume after I processed it all, as that wasn't apparent when capturing the flare. Seeing wasn't great so the live view was pretty wobbly, and there were a few very thin hazy cloud patches coming across the fov during the captures, hence the very variable brigh...

First time imaging for two months and I captured this nice little flare that fired up for about 3 or 4 minutes yesterday afternoon, Sunday 1st Nov. Captured using Daystar Quark, very basic "el cheapo" 102 mm f6.5 Nova brand Achromat on Celestron AVX mount with a GSO reducer and ZWO ASI174MM CMOS cam...

Thank you both.

Chris it's an 80mm EDT while using a 0.5FR at the Quark end.
Thanks for that Ewan.

Re: Timelapse of yesterday's large looping prominence.

Beautifully done. I took notes on your technique. Yet to try anything like this! Hi Nick. I'm very much a beginner at these solar timelapses too. You certainly don't need to be very experienced at it to get a half decent result. I think this is only the third one of these animations I've tried. The...

Thanks for the nice comments everyone. It was very flukey that I got it as I was heading to have a look at the big filaments rather than any proms, but as I got the Quark heated up to working temp I did a quick check of the Gong Ha webpage and saw that enormous prom there so away I went with the two...

Timelapse of yesterday's large looping prominence.

Attached is an animated gif of a timelapse I made of yesterday's huge prominence. This is 2 hours worth of the action in the prom, from around 1 pm to 3pm (New Zealand time). I captured 120 5 second avi files a minute apart using Firecapture's "Autorun" feature, stacked each avi to one image with Au...

Hi Luke, Mark, Thanks for that idea on the shorter nosepiece and 1.25 inch reducer alone Mark. Luke, good to hear the glasspath and reducer works for you.
