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?
Heyyy its meee kronos and i have been wondering about getting a filter...I really want the best contrast and brightness i can on my nebulas(i want to view M42 M57 M27 M31 M81 M82 and lots more) with my future 8" dob. Is this filter really going to help me?
If it just a matter of quality of the filter itself can you suggest a better one in the same price range?
Or will not the uhc filter help me in general .IF so can you reccomend another one?
Also is this https://www.firstlightoptics.com/uhc-oiii-visual-filters/uhc-filter.html this https://www.firstlightoptics.com/uhc-oiii-visual-filters/es_uhc_filter_125.html https://www.firstlightoptics.com/uhc-oiii-visual-filters/baader-uhc-s-filter.html this better?
Heyyyyy its me againnn . I am trying to find a good UHC (Open to OIII ones aswell) filter to use for nebula observation. I ve stumbled upon these 2 :
1 Explore Scientific UHC Nebula Filter
2 UHC FILTER
Can somebody tell me which is better? Or if somebody has one themselves , can tell me if they are worth buying or just saving for a better one.
If you want to you can recommend me a good UHC OR OIII filter for viewing Nebulas thanks.
