Re: it seems that my Quark is not reaching the working temperature

I will try to follow the both advises and compare the results. Thank you! Roman

Re: it seems that my Quark is not reaching the working temperature

Thank you Raf! I do have a good 1.6x extender and it is on my list to try next. Thus you confirm that the ambient temperature may be a problem... is not it strange for a solar filter to not work under sun light, xD. But I understand, of course. Why longer focal length helps to improve the image? The...

Re: it seems that my Quark is not reaching the working temperature

thank you, Mark. I will try different cables and also check if the green light appears with the covered telescope (as for dark frames). The power source was a standard wall outlet. Thank you for the exposure advise - yes, for the frames posted the histogram was almost 100% filled. I am glad the the ...

Re: it seems that my Quark is not reaching the working temperature

the air had too much turbulence (it was noon and it was hot), it was hard to focus. I posted below a single not processed frame and a gif-file with 20 consecutive frames.

it seems that my Quark is not reaching the working temperature

the green light does appear after a while if the filter is on my table (not connected to anything but power), during a real observation when the filter is connected to the telescope it seems to fail to reach the working temperature and the green light does not come... what could be the reason for th...

Re: asi120mm-s DIY cooling

that is great! I was thinking about cooling my ASI174MM from the very beginning. The first idea was to use liquid cooling from computer kits... Now I would consider Martin’s idea. Interesting how it will work under the sun, the working temp of the camera is -5C or lower, but actually without cooling...

Re: advise needed for double stacking DS Quark

btw, this is the person I admire and follow on flickr. He is amazing, I dont know his name though. So one of his set ups which has inspired me for double stacking in particular and for solar astronomy in general: https://flic.kr/p/SPo9v6

Re: advise needed for double stacking DS Quark

Thx, Mark!

I was thinking to put a Lunt etalon behind my Quark, I believe I have seen some people do it. I asked since I was not sure I could improve much from 0.5a and what will be tech challenges. I would definitely try it before buying if I can.

advise needed for double stacking DS Quark

Hi All, as a new to solar astronomy, may I ask your opinion on what would be the best filter to stack with DS Quark H-alpha "Eyepiece" Chromosphere model? 0. DS claims 0.5Å - is it true? can it be improved? 1. looking for the best quality (let's assume that price does not matter, but budget options ...

Re: Why my Quark always refused to work...

Thx!!! I have not thought about removing the original BF until I found this thread, now it seems like a good idea.

I'll try to be active on this forum - have too many questions, xD

Thank you again

Re: Why my Quark always refused to work...

Hi Raf, I mounted the 25mm andover in the cell from a real cheapie barlow lens (throwing the lens away) and then mounted that on a 2" to 1.25" filter adapter https://www.365astronomy.com/365Astronomy-2-to-1.25-Filter-Adapter.html I then replaced the 2" snout on the Quark with a slightly longer one ...
