Since version 3.5 of KStars, a new plate solving capability has been integrated within Ekos. Kstars and Ekos – Plate Solving for alignment
Plate solving online driver#
Using the INDI driver for your telescope mount first time- assuming you do not have a dome, make sure you disable the “dome policy” in the INDI driver options tab otherwise you cannot unpark your mount….Set up time and location in Kstars and Ekos and avoid guiding and alignment issues – see my separate article here.I did my first nights imaging at 8 bit by mistake, a clue was the smaller file size and inadequate image quality!! First time you connect your main camera via INDI, check that you have set the format to Raw 16 bit and save the config.

I download all the files except the very large USNO NOMAD catalogue per below: Kstars – go to “Data” on the Kstars main menu – download the visual imagery for Kstars, it may take a while but it makes a big difference.
If you are using Ekos / Kstars on a Raspberry Pi either with Astroberry or Stellarmate don’t forget some basic configuration steps worth doing on a cloudy night before you start imaging: Kstars and Ekos – Initial Configuration stuff See the picture below for my settings for the 294 for WB_R and WB_B. Failure to do this will mean your darks do not subtract the noise correctly too. Since the data coming from the camera are saved in FITS files rounding errors and clipping of high values will arise (Such a complication is generally avoided when the ASCOM camera driver is used instead of the native driver). Only in this way will the real raw intensities be saved to disk in the FITS files. So it is important to set the values of both parameters to 50 and subsequently apply ‘ Save Config‘ to persist it next time you boot up. Unfortunately the results of this multiplication are also written to disk in the FITS file. The intensities of the red channel will be multiplied by WB_R/50 and the intensities of the blue channel by WB_B/50. This is achieved by two parameters, WB_R and WB_B, data range 1 to 100, the default values are WB_R = 52 and WB_B = 95.
Plate solving online software#
The ZWO SDK enables the user in the acquisition software to control settings that influence the white balance of a displayed color image. If you use a ZWO OSC camera, be careful when using it with EKOS. Here is an odd one that got me when moving from APT (using ASCOM) to EKOS (using INDI).
ZWO OSC cameras and PixInsight processing I discovered this the hard way that you must take new dark frames using Ekos to ensure correct dark frame subtraction in tools like PixInsight to work properly. Never use Dark frames or a Master Dark captured using other tools, such as APT.
