Solar viewing is a brand new Genre of Astronomy for me and would appreciate a bit of wisdom to get started. The DayStar Quark looks fun. I have the refractors, at least enough to get started with and the mounts along with Televue 2X and 4X Powermates and the power supplies already, so those are not in question.
My first question, in two parts. Equipping a DayStar Quark H Alpha device for service. First which model would be best to start out with. The Promenance or the Chromaspere? Is there a favorite?
What filters do I need in conjunction with the Quark? I do night Vision Astronomy and I use 6nm, 7nm and 12nm H Alpha narrowband filters and various IR Longpass filters from 610 to 685nm.
What focal length eyepieces would you recommend for the DayStar Quark?
Final questions. Should I forgo the Daystar Quark Device in favor of a Hershel wedge or should I have both?
THANK YOU ALL AND KEEP LOOKING UP Jethro
Get the Chromosphere version. It not only gives you better surface detail, but the proiminces are still nice. No brainer here.My favorite. I've looked thru both devices.
If you have a 100-130mm refractor, for many reasons,use this aperture refractor. It gives you what I call the "sweet spot" aperture when using the Quark.
If you have a 2" diagonal,use it. All you need is a 2" UV/IR cut filter you can get from any dealer. The filter would just thread onto the nosepiece(objective end) of the diagonal.
You would also need an inexpensive Solar Finder to point towards the Sun SAFELY, to locate the Sun looking thru the Quark. You would think why would anyone need a finder for the Sun? Trust me,you will need one,especially for the close up/hi-resolution views you get with the Quark.
Simple Plossl eyepieces work best with the Quark. Televue 32mm and Televue 40mm Plossls work great. If your seeing is good,you could go higher magnification to a 25mm Plossl, but going below 25mm mostly will not show crisp visual views with the Quark.
Hershell wedges are ok for white light views of sunspots, but believe me, nothing beats H-Alpha views for solar. Just my opinion from solar observing thru white light or H-Alpha, H-Alpha wins every time. The Chromosphere of the Sun in H-Alpha is truly amazing! White light is very limited in what it shows, but H-Alpha takes it to a different level.
Oh,I've been doing solar for ~18 years and looked thru just about everything and owned Coronado,Daystar,and Lunt telescopes/filters, so I do have experience with solar observing.
I am using the Chromosphere Quark 100% of the time,with William Optics binoviewers,with Lunt 102mm ED refractor,and Lunt 40mm solar telescope in tandem to get FULL DISC and zoomed in visual views. I love it. Here is a photo:
