Good informative video, but I totally disagree with the 650s exposures, especially with your camera, the 2600mc pro is the IMX571 sensor, and you get to a point of diminishing returns after about 300 second exposure, and if you have an issue with guiding or clouds or similar, and have to throw subs away, you are losing loads of data with over 10 min subs. You are better with unity gain and shorter subs, even more so with broadband targets… I use 2 min subs for broadband and 3 min for narrowband with essentially the same camera…
I 100% agree with you on this. The last few times I have been out my recommended exposure has gone up tremendously, and my demonstrated settings have not changed. I have a message out with SharpCap to see if we can troubleshoot this and then I will post an updated video solely on the Smart Histogram. The purpose on here was just a demonstration of the software and with only 2 decent imaging nights in the last 3 months, it’s making it difficult to produce videos. I unfortunately had to take this one and run with it.
@@Hidden.Light.Photography yes I think sometimes the algorithm used in these softwares is just basically overthinking it all, in Sharpcap there is a sensor analysis and that should give you an idea of ideal exposure length to use, at a specific gain setting, as at the end of the day, you only need enough of an exposure to swamp the read noise, which is pretty short for these sensitive cameras and broadband filters… I have tried 2,3,4,5 and ten min exposures with mine, and TBH, there was barely any difference between 5min and 10min, and also between 3 and 5 no real difference, so settled with 2 for BB and 3 for narrowband, but I have the QHY version of the camera and use the high gain mode, not sure how that measures against ZWO
I reran the sensor analysis on the program and also SharpCap is fully up to date. I am getting literally no different in recommended exposure between using L-Ultimate or L-Pro despite the heavy difference in light getting to the sensor. I used to be around 100s-300s recommendations even with the L-Ultimate. I went out one night in October and my recommendation was 1150s for IC1805 and just 2 nights prior to that I was 450s on the same setup and target. Something happened, but have not had a chance to get it fully diagnosed. I re ran sensor analysis on both cameras since then, but as you can see in the video it hasn’t made much of a difference.
