Thanks a lot! Congratulations to everyone! Looking forward to the next competition. Clear skies, Vlad

Hello everyone! Image processed in PI: - Decon and Denoise on each channel - DBE - Histogram stretch - Channel combination with PixelMath - Applying Ha as Luminance with LRGB Combination - ACDNR - Curves transformation - Saturation boost - Reducing Star Sizes with Morphological Transformation -Dark Structure Enhance Clear skies, Vlad

I will finally get rid of halos 😆 (hopefully) Clear skies, Vlad

You can try Stellarium.

Good luck with the new setup!

Hello everyone! Image processed in PI: -LRGBCombination (RGB combine) -DBE -BackgroundNeutralization -EZ Denoise -ColorCalibration -DBE on Lum -Stretching using HistogramTransformation -Applying Luminance Image with LRGBCombination (adjust saturation and check off chrominance noise reduction) -SCNR -MultiscaleLinearTransform-CurvesTransformation-Reducing Star Sizes with MorphologicalTransformation -Dark Structure Enhance

Congratulations!

First time when I process something in PixInsight. Hard to learn but very useful tool. Had big issues integrating Ha in RGB (tried for a week to process and combine Ha but without any satisfying results) so the image is without Ha. Main steps (these steps were not performed in this order, they are written as I remember): -Cropping with DynamicCrop -DynamicBackgroundExtraction -MultiscaleLinearTransform -Matching the Images with LinearFit -Stretching using HistogramTransformation -Colour-Combining with ChannelCombination -Performing the Colour Calibration with PhotometricColorCalibration -Removing the Green Colour Cast with SCNR -Applying Luminance Image with LRGBCombination -BackgroundNeutralization -ACDNR -Deconvolution with DynamicPSF -HDRMultiscaleTransform -CurvesTransformation -Reducing Star Sizes with MorphologicalTransformation -Saturation Enhancements and Hue Shifts with CurvesTransformation

I will definitely try that. Thank you! Yes, I've deleted phd2...good to know that I can just rerun the installer. Thank you!

I've bought today a serial to USB cable. I intend to use it tonight. Thank you for the advice! Unfortunately I don't have that logs...idk why.. First of all, thank you so much for your time and for all the technical analysis. I'll make all the recommended adjustments and also post the logs to the PHD2 Help group. Hopefully I will be able to guide tonight with those adjustments and the USB-serial connection to the mount. Cheers, Vlad

Adding the correct logs. Sorry. PHD2_DebugLog_2021-03-24_201800.txt PHD2_GuideLog_2021-03-24_201800.txt

Hello everyone I've started astrophotography in September last year with the following setup: Telescope: WO ZS 61 Mount: EXOS-2 PMC8 (wireless connection to the laptop) Camera: ASI1600MM Pro Software: APT/N.I.N.A Had no problem with this equipment, taking mostly 60s subs (rarely 90s with round stars) without guiding. So...heading to the problem... Recently bought an ASI120mm camera with an Artesky guidescope. On the first night with this setup, I've managed to take approx. 5x300s in N.I.N.A. After that my mount got suddenly disconnected and then PHD2 never worked properly. I'm struggling for more than 2 weeks... Having the following issues on different nights: 1. PHD2 error messages: - pulse guide command to mount has failed - RA calibration failed star did not move enough - PHD2 is not able to make sufficient corrections in RA - PulseGuide command to mount has failed - guiding is likely to be ineffective - Although I start calibration within +/- 10 degrees of celestial equator I get the following message: "Calibration this far from the celestial equator will be error prone. For best results calibrate at a declination of -20 to +20." 2. The most recent one that happened 2 nights in a row without any error messages is that PHD2 loops infinitely when I start calibration. Tried the following "fixes": - increasing calibration steps in PHD2 - using another USB Type-C cable (tried connecting guide camera to imaging camera and also tried connecting guide camera directly to the laptop) - tried different USB slots - rebalancing - reinstalling all the software (ASCOM drivers, PHD2, N.I.N.A, APT, ZWO drivers) I'm hopeless... You can find my last PHD2 logs in the attachment. I'm opened to any ideas, suggestions (buying a more capable mount is not an option at the moment) Thank you in advance!

Well done everyone!

All of that makes sense. I really appreciate your input. Thank you, Vlad

Hello everyone, I'm looking to buy some NB filters and wanna make the best decision. 1. Does the size of the filter impacts the quality of the image? (is it a big impact?) 2. I know that lower HBW is best, but... for example: does the difference between 35nm and 7nm is worth the price? 3.Can you recommend some H-alpha, OIII, SII? Thank you in advance! Cheers, Vlad

Congrats to everyone!

Hello, You can only use it on one of the individual channels (R,G or B ). Here is a nice video about image processing that also includes SiriL. Cheers, Vlad

Download won't start. Apparently, the link provided by @vlaiv worked. Thank you!

Hello everyone, I've read about Starnet++ lately and I wanna give it a try. Tried to get it from here but there are some issues. It seems like I can't find any viable kit. I would really appreciate if someone can provide a link to download. Thank you, Vlad

Hello Jeff, welcome to SGL

Thank you for the data! Processed with SiriL and PS. Steps: Channel Combination>Curves>Levels>Saturation/Hue>Vibrance>Curves>Noise Reduction>Unsharp Mask>Star minimization>Luminance layer Good luck everyone, Vlad

Didn't modified the camera and I don't intend to do. I bought the camera from a local store. I'm pretty sure you can find some decent gear online in UK.

Hello and welcome I'm using a Canon 450D that was bought at 200$. I'm pleased with it (as a beginner). About the magnification you can probably find some useful information here. Also, http://astronomy.tools/calculators/field_of_view/ has some nice features. Clear skies, Vlad

Congratulations! Looking forward for the next data release.
