Re: ASI 174MM and Firecapture - endless issues - looking for alternatives!

+1 for me. I've been using an ASI174 for a few years and it just works. i've alsways used Firecapture too.

USB3 can be sensitive to cabling issues, do I'd start there. Do you have any hubs in the system?

Its not a focus technique, but a post-processing sharpening routine.

Hi,

think you are mixig gain and gamma here. For the ZWO cameras the neutral (or linear) gamma (not the gain) is 50. Can also be set in Firecacture by setting Gamma to off.

Rgrds,

Paul

Oops....so I am.
My apologies and thanks for the correction

Your advice is to use Gain -neutral-, guess in Firecapture that means slider all the way to the left ?
With Firecapture the neutral point for the ZWO 174 camera is 50 on the gain.

Re: ASI 174MM and Firecapture - endless issues - looking for alternatives!

I'd also look at the USB3 cables that you are using. I have a 3 metre cable that causes the camera to drop frames and disconnect in FireCapture. Stick a 2 metre in and it works fine. This may suggest a power issue as Rupert (Astrograph) has suggested.

Re: ASI174MM versus ASI290MM for Lunt LS60-B1200

The pixel size on the 174 is a bit big for the 60mm. I use a 2.5 Powermate with mine and find that the proms get a bit blocky due to the pixel size. It works great with a Quark though. The 290 has 2.9 micron pixels which will suit the focal length of the Lunt much better. One thing to consider caref...

Re: to Quark or not to Quark??

No, I wouldn't swap my Lunt L60 for a Quark, because they both do different things. The Lunt is brilliant for full disc shots, and can be Barlowed up to get in closer. The Quark is limited to close in shots. The Lunt is better when the conditions are poor as the focal length is a lot shorter. plus y...

Thanks all! :bow Excellent Stephen! That new scope seems to be performing well! It's more to do with the newer Quark, to be honest. I'm amazed by the difference in quality.

Re: Quark and TS 115 APO

Ive used a Quark with an Altair 115mm triplet (the same as the TS one). I used a 2" Baader UV/IR with no problems.

I've replaced the 115mm with an Esprit 120. I intend to use a Baader 35Nm Ha filter as the ERF. Having said that, i've also been out today and used the UV filter.

Re: A couple of questions someone may be able to help me with please.

The Baader filters are pretty tough. Just blow the dust off with a decent bulb-blower. if there is stuck-on stuff then Baaders Wonder fluid and cloth will sort it. Regarding guiding, the small sensor of the DMK might be a bit restrictive. However, people do use them and if you pair it with a widefie...

Re: best autofocus software

Do you mean an autofocus program like Focusmax? I've never heard of a focus routine for planetary or solar. Deep Sky imaging can use diffraction or HFR on pinpoint light sources (stars) to calculate the focus point, but I don't think that anything like that is possible with solar imaging. For me, I ...
