Thanks a lot for this interesting video. It's a help because I am going to buy a Daystar Quark, too. Especially the placement of the UV/IR cut filter is now clear!

Hey Jeff nice overview I've been so enjoying my time with the Quark. You have some lovely images there.

I put the Sun filter film on my 50mm raci finder scope with a stiff leather shadow shield to protect me from the Sun while viewing. I mounted Daystar's 60mm Scout Chromosphere telescope onto my 150 Newtonian's rings as they have 1/4-20 screws. Great viewing. Discovered with the artificial lens in my cataract surgery eye I see more than with my other eye and I can see the Ca-H filter and most can't. I had the mirrors on my old C6-N redone as O.W.L. had a sale, they refigured my primary too, get this, to a Strehl ratio of .986 and 1/12th wave, very happy with its near perfect focus. Then they aluminized my mirrors to 96-97% reflectivity. When I got it back and put it all together and collimated it I was blown away at how good my view of the crescent Moon was. Good seeing conditions so I put a 6mm and looked at Mizar. The two stars were fuzzy before, but not now. They were nice nearly spherical round stars, not mere pin pricks. I live in Southern New Mexico and the Jet Stream report said calm and up to my Bortle 2 viewing site I went with a couple of guys from the Astro Club. I took my 3.2mm ED Starfinder eyepiece at 234x and took a look at Jupiter, it was like looking through Hubble almost, it was so sharp. I then unscrewed the lens element out of my Barlow and put it in the 3.2 adding about what supposed to be half the Barlow, but was realistically maybe a third more magnification considering the distance from the small 1/8th" bottom lens. Anyway Saturn had never looked that close before except in something much bigger 10" to 12" scopes. It came back so much nicer I HAD to put a dual speed Crayford focuser on it. So for around $500+ I got Takahashi quality in a 6" reflector. Those Starfinder ED eyepieces are 62 degree fov and are excellent. I can't afford $200 eyepieces, but being in an astronomy club I've been able to even use a Mead 16" telescope at our observatory in a state park. I also used some Televue EPs and Explore Scientific really wide angle ones it was like sticking my head out of a window the field of view was crazy, but the prices were too. I bought a Sky Watcher 102mm MCT for less. (nice scope worth every penny. The extra low dispersion EPs I get from Agena for $75 are really good. That ED 3.2mm EP is great for small short focal length scopes, but it is about as much as my scope can handle. I learned to never grab the Newtonian with the front dust cover off if I didn't want to re-collimate the secondary mirror. Flexes those vanes just enough to knock it off a little, just an FYI.

Nice and informative video Jeff! I have had the Quark Chromo for a couple years and planned on doing a lot of work with it but got side tracked. However this summer, solar imaging will be my goal. I have an ASI178 but may upgrade to the ASI174 mainly because the faster rate and larger pixel size. Interestingly I saw couple other videos where the presenters said Global vs. Rolling shutter did not make much of a difference. Awesome images! Cheers Kurt

Great presentation and comments on the various pieces of equipment used - you have definitely mastered the art of solar observing and imaging. Looking to get started with a Genesis SDF that has been hiding in the closet for far too long... Charles in S IL

Great work as usual Jeff, I really enjoyed the animation of the solar prom. Tim

Wow! Very informative and helpful.

Quality content! Thank you, I learned a lot!

Nice.. thanks for share

Great Video Jeff! I hope we can see soon more of your sun photos! Since a few days i use the Quark GEMINI from Daystar :-)

I find a simple way to slew to the sun, with a quark in place, is to use the histogram from the camera. I know I can get close by using shadow, as you do, or an almost goodly polar aligned rig. Using Sharpcap, I up gain and exposure until the histogram shows a peak coming in at around 2 or 3%. From then it's chase the light, edging slowly ENW or S.

Great video, Jeff. I think this one should only cost me about $1800!

Your grins tell me everything

Great video. Do you take flat frames during your captures

Hello, congratulations for this very explanatory video, I have a SharpStar 94EDPH and my salesperson recommends an ERF filter (90mm up to $350) at full aperture and a UV-IR cut filter in front of the Quark for an aperture greater than 80mm? do you have a URF flter in front of your full aperture? thank you

As always, a very informative video. Have you used the Quark with your AP 130?

And please some tutorial on how to edit your pictures and make the animation. Thanks

Thanks for the video... I have the Chromosphere quark, I use it with William Optics gt 71 and some times with televue 2× power mate... So to make sure I understand well if you turn the dial to the right do you increase or decrease the wavelength? Another question, I see a lot of dust and a spots in my no matter how much I clean everything, please make videos on flat frames calibration... Many thanks

I just watched your video and found it fascinating. You did an excellent job of explaining every detail, especially to a lay person. I was completely immersed in every aspect of the telescope and the solar attachments. But I do have one complaint. I hated the background music. I use headphones and its too loud and once the music and snare drum gets into your head, it's difficult to maintain concentration on your voice track. The music is completely unnecessary and very distracting. Sorry for complaining, I would really have loved to have watched the video all the way through, but had to give up. Mid 70's and don't have all that much patience any more.

Excellent video! What resources did you use to learn this?

Hi! Why don't you use front mounted D-ERF? You would keep the heat out of the scope. Having uv/ir block just in front of the Quark you are letting heat inside the OTA. How much nm does your Optolong blocks? Where do you save your files? On your phone or on AsiAir? Btw, we recorded the same prom. Nice work. :-) Best regards.

Nice explanations and very nice flare capture. At 12:54 you say your are capturing "10 second videos". But in Video mode the Asair the maximum individual exposure is only 1 second (and you also say you are capturing at ~16fps).. Please explain. It seems possible that you capture (automatically?) a large number of 10 second duration Avi videos (each with many very short exposures) then you stack the data within each individual video then animate the stacked images. I would love to know how you do this.

Have you tried the Sodium D, Magnesium or Calcium H Quark eyepieces from DayStar Filters?

Is there an image problem with the off axis due to the position of the front hole out of the secondary mirror?

Can I use this with a newtonian telescope using an area reduction on the front of It?

I've used solar film to safely observe the sun. I have a 102 triplet apo and I'm very nervous about pointing it at the sun without something in front. Will my lenses be OK?

at 12:32 you had a bogie. could be a bug, could be a satellite?

The background music makes it difficult to hear the narration, especially getting on in years and the hearing is not what it used to be. I am a lot more interested in the narration and learning of others experiences. Thank you for making your presentation and sharing it.
