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.
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.
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?
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.
