Re: Daystar DS 60

Hi all Just a little update on the Quark unit. I have always had problems with slight vignetting when using the bino head on the end of the quark unit. This vignetting was just a random dark area to one side if the view. After going through all the optical alignment and bolting everything up solid I...

Re: Daystar DS 60

Thanks Mark that sort of confirms what I was thinking with the Quarks, I ordered the ss60-ds from FLO for that exact reason and glad I did, although the first scope was not questionable (it looked like it had been dropped or banged about a lot in transit somewhere) FLO were very good. As for the cam...

Re: Daystar DS 60

Hi Mark That makes sense, when I take the etalon unit off the telecentric I will try and confirm that. As the seeing was so bad today I had a go at seeing if I could get the whole sun on my 1/2" chip, no, you need a focal reducer. What I did find though is I could get no better a raw image than atlg...

Re: Daystar DS 60

Hi This picture shows the same thin metal stop at the eyepiece end with just a smaller hole. It does make me think in the Quark philosophy that It may just be a standard etalon with problems around its edge but is perfectly usable in this format of the ss60-ds. It maybe though that once removed and ...

Re: Daystar DS 60

Hi Mark I agree with the variability, I haven't taken the Quark part apart so dont know if the etalon is smaller or just has some edge problems as it looks like it may be the same etalons but just masked off to hide this and therefore cheaper. It does have the zonal dark light areas that most etalon...

Re: Daystar DS 60

Thanks Stu It seems to me to be the lowest priced way to get reliable H alpha views. It also seems the SS60-ds is limited by the objective and not the Quark unit. The Quark unit is easily detachable as I found on the first scope that was sent to me, the scope was almost in two halves, it just has a ...

Re: Daystar DS 60

Hi Nice image and nice to see it is working well. I think my first one had been dropped several times by couriers even though FLO had packaged it really well, it was like opening a Russian doll of boxes. But the scope itself is just in a plastic bag in an empty box with a little foam about 10mm thic...

Re: Daystar DS 60

Hi I have one of these scopes. First thing I would ask is what can you see visually? Does the sun's disk change appearance when adjusting the tuning knob? I ask this as my first one was in a bit of a state, falling apart, lots of paint flecks inside, machining swarf and objective/focuser out of alig...

Re: ZWO ASI178 "grid" issue

I forgot your drift needs to be 45 degree to the pixel array so twist your camera so the image drifts from one corner to the opposite corner.

Re: ZWO ASI178 "grid" issue

Hi I have the same problem with my QHY5 II M I have found that having a little drifting of the image removes this. I can set the speed of my RA motor so this is easy to do on my scope but if you are quartz locked you can't do that. You could try leaving the RA motor off when recording as the drift o...

Re: Flats from near full disk?

Hi Maurits Yep the second image shows the info is all there and easy to bring out once it has been flattened. I will be up for trying Valery's method when I get my full disk setup it does sound good. One tip I use for deep sky flats is a white drum skin over the objective pointed at the sky or a lig...

Re: Flats from near full disk?

Hi I had another play with the image.
Shadows and highlights and added colour.
Not to bad, maybe a little over processed in places but does show some even detail.

Re: Flats from near full disk?

Hi Maurits Hope you don't mind but I had a play with your image above as I am interested in the same thing, removing variations in brightness. It sort of works but as Mark says you can't remove the bandpass variations. What I did was copy your image, then I saved two copies. One copy I used gaussian...

Re: 2 small spots

Hi nice image Paul
I just got a 5min break in the clouds and wanted to report some lovely detail in the spot near the edge of the sun
It has developed into a ring of very small spots with a bright centre in Ha light
good target for high res imaging

have you done any more with the solar scout?
Also how do you find the visual image and the tuning?

Re: Thursdays Hazy Start to the Day - 16th May

Hi Mark I totally get the transparency issue, not as much of a problem with a smaller object like a planet but the sun being so large can have many moving brightness across it that sometimes the staking software cannot cope with. Varying transparency is a major problem here in the Peak District as a...

Re: Thursdays Hazy Start to the Day - 16th May

Hi Peter It is and always has been an interesting argument this one. Many visual planetary observers preferred slightly hazy seeing because of the stable air that comes along with it, their reason for this is you record what is actually there and not fleeting glances of your imagination. This argume...

Re: Thursdays Hazy Start to the Day - 16th May

Very nice detailed images Mark Do you think that the haze actually works in our favor much like for planetary imaging and viewing? When it is hazy much more of the atmosphere is stable, this makes for better frame rates and although the contrast is a little lower it is much easier to get good focus....
