William Optics Z103 & Daystar Quark Chromosphere

Recommended Posts

Last summer I spent a lot of time observing and imaging the sun with a WO Z61 and Quark Chromosphere. Recently I have acquired a WO Z103 and if the sun ever comes out I would like to use this refractor for imaging as well. Question I have is with the wider aperture of the Z103, is it safe to use with the Quark and is an energy rejection filter needed?

I previously read that it should be ok up to c100mm without an ERF but I cannot see any reference to this on now on the Daystar website.

Thoughts welcome.

I used the Quark for visual observing  with my 110mm refractor, without an ERF, for a long time and had zero issues,. At the time 110mm fell in the safe zone as detailed in the literature from Daystar 😀 I don’t know if the literature has since changed to state otherwise.

as above you will be fine, i use mine with upto 120mm with just a ir/uv filter. charl.

      For sale is my Daystar Quark, Chromosphere version.  It has had infrequent use and I can't justify keeping it. Works superbly with my ED80.  It was purchased in July 2017 from Widescreen Centre so is still well within the 5 year warranty period.  I am looking for £625 posted to a UK mainland address.  Everything is complete in the box including instructions, USB cable and power adaptor.  Payment by bank transfer please.

      Hi,
      I currently have a Lunt 50THa and I am looking for something showing more detail and contrast on the sun's surface. I have been considering the new Meade SolarMax III 70 Double Stack, the Lunt 60 with DS (fairly expensive in comparison) and now stumbled across the Daystar Chromosphere. My key considerations:
      - I love that I can just take out the Lunt at lunch time, put it on a photographic tripod, and I am up and running in about 5min. 
      - When travelling, it would be easier to have one telescope to take with me for day and night use
      - Cost is certainly an aspect - I do not want to spend more than about 3000 pounds.
      May I get your input on a couple of assumptions I am making (and which may be completely wrong - sorry, I am not a telescope expert, I just love using them...)
      - The only purpose of double stacking is to get a narrower bandwidth using (cheaper) filters with a wider bandwidth - by using two 0.7nm filters tuned to slightly different bandwidth the Lunt and the Coronado achieve 0.5nm effective transmission.
      - A Daystar Chromosphere with a transmission of <= 0.5nm will hence show me the same detail as a Lunt or Coronado Double Stack with a single Etalon
      - A refractor up to 80mm does not require an additional ERF
      - A relatively cheap achromat will do - as I am only observing at a single wavelength, the correction for multiple wavelengths really does not make a difference (at least for H alpha)
      So on that background I guess an 80mm refractor with the DayStar will give me a really good solution  am I right?
      Best

      Hello from Florida, 👋
      I wasn't able to image the 4th and final day as AR2729 rounded the limb due to work, but I was able to latch on for three days while it had lovely visible umbra. This is spanning December 5th, 6th and 7th. Imaged in 6562.8A wavelength.
      B&W:



      Colored:



      Captured with:
      Celestron 150mm F8 Refractor (CR150HD)
      Daystar 150mm ERF
      Daystar Quark Chromosphere
      ASI174MM Camera with 2" GSO 0.5x Focal Reducer
      Very best,

      I am thinking of getting a Lunt 50mm scope. I want to image as well as observe. I am thinking I could put my ZWO on the scope and capture video. My question is, does focal length in a solar scope relate to the FoV as it does for a non-solar scope? The field of view calculator (http://www.12dstring.me.uk/fovcalc.php) suggests I could just about get a full disc with a focal length of 350mm (the 50mm Lunt), but not with a focal length of 500mm (the 60mm Lunt). Is my logic correct?
