Focuser mod to improve Sharpcap Autofocus

Hi, I have always had an issue with the 10:1 reducers on both refractors that I have owned with the ball and cup arrangement that gives the 10:1 reduction on the rack and pinion. I have found that the friction is not perfect even after adjustment and during the course of an evening there is always a...

Re: Brain function Exposure /Gain vs Star size

Hi Robin, I am refocusing between each filter even though they are allegedly par focal, the telescope is a refractor and will never be diffraction limited as it is a 130mm LZOS triplet with a strehl value of 0.98 so it will always being seeing limited never diffraction limited. I see similar effects...

Re: Brain function Exposure /Gain vs Star size

Exactly before running a set I ran the brain then went into imaging the live stack + saving individual frames immediately after so they should be fairly representative of the sky brightness.

Re: Brain function Exposure /Gain vs Star size

Hi Yes red was the first filter up and we started the imaging run at about 22.50, then green was about 22:50 and then flip and luminance from 23:50 and finally blue at about 1:40 until 14:35. So it is possible that it could be related to astronomical dark times but would the exposure not have calcul...

Brain function Exposure /Gain vs Star size

Hi, As we have had a couple of good nights I have been playing with the brain function with my ASI1600MM Pro and LRGB filters, as already stated elsewhere I do not have calibration frames for everything the brain proposes so I adjust the gain to 75 as it usually recommends 64 and then adjust the exp...

Re: planner for programmed poses

Hi,
At the moment you have to do them yourself manually but I believe Robin is looking at automating this in a future release. I am sure he will be along to confirm/deny this at some point .

Re: Saving the camera settings in livestacking

You can do most of this in the name of the files as I set up the raw frames naming convention to add the filter exposure gain offset etc as part of the filename an example of one of my frame names would be as below is this the type of thing you are after. The overall folder is named as per the objec...

Thanks for the coment, the next target if the weather ever improves is Markarians chain which I have never imaged as a whole which should be fun.
