Re: Solar Images taken May 9th 2019 and a question.

Hi Martin, can confirm the ND3.8 gives much better results than the ND5. I have been using the ND5 in my C8 at prime focus and this still ok, but adding extra filters (baader continuum ...) will make exposure to slow. Also if adding any barlow to increase f/ratio will need the 3.8. (ND 3.8 is diffic...

Re: Electronic focuser the Sesto Senso.

Hi, got that focuser recently but could not do much testing yet. (Hospital took me out-of-business again) I wanted to attach it to a cheap GSO Crayford. It works, but because the 10x spindle of the GSO is not really straight and the Sesto connector is the stiff type that gave some wobble. I then att...

Re: FireCapture: How to get 12bit video.

Mark, is there a way you can compare the both files on the image data? I have no experience with PGR cams but it looks odd to me that there are differences. I know from Torsten he just writes down the values coming from the cams in the SER files and that should be no different to for Fits. I could d...

Re: I need a laptop that matches the speed of ZWO ASI174

Hi, cheapest option probably is to build an SSSM. Then there is no need anymore to transfer huge amounts of data from the buffer to the disc (since only good seeing moments are saved) That with a good USB3 connection and enough memory (I use 16Gb) should do. Other option, but the laptop needs to sup...

Re: Calculating Field Rotation With an Alt Az Mount For Solar Timelapses

Mark, have you tried this in AS!3? Might solve your problem. No idea if it works. (but seems you need to calculate de rotatiion degree first, think I have this somewhere but need to dig very deep ....)

Is is under advanced -> experimental features

Re: First solar shot ASI290

Not only FOV that counts in this case Mark. The IMX has 3.75µm pixels. So with the TAl to get same resolution you would need 1.3x barlow limiting the FOV again. (For me that 290 and the TAL at f/10 looks a good choice. (Maybe undersampled in blue,but red should be ok fro Nyquist. Altthough tendency ...

Re: FireCapture: How to get 12bit video.

have file type set to fits. Mark, won't that slow down capturing too much?? Then you end up with a huge amount of files for 1 capture (lots of overhead). I would just leave the file type SER and recording 16 bit. What I don't know is how PG passes the information thru the SDK. If they pass the 12 b...

Thanks for the comments everyone. @Brian: hope you get good results with the plugin. After using it "for real" a few times now, I think there are a few things that could it make easier to use, so I am planning to do some work on it, mostly on the plugin. That will take some time (will need a new "he...

Re: AR12736, Lunt BF1200ST and a BF question

The BF can be removed from the bottom of the device by unscrewing the retaining ring, no need to open the Quark. Noop, unfortunately not true anymore. That retaining ring is fixed with an ugly screw. You can unscrew the 2'" and 1.25" pieces, but not the the part that holds the telecentric and bf. (...

Re: AR12736, Lunt BF1200ST and a BF question

I removed the BF of my Quark (very simple, indeed)
Probably an older Quark? There is a security screw that does not allow the black body and telecentric to be removed. That screw should be unscrewed first, but it has that security torx(?) model. Tried a few but could not get anything to fit.

Hi,

these are GOOD!
In #1 to #4 it did not give much benefit going from 4.8 to 6m FL, but that granulation shot is superb!
Also like the K-Line shot.
