LCG vs HCG mode - Beginning Deep Sky Imaging - Cloudy Nights Read noise alone is not the most important factor for a sensor in DSO astrophotography, the dynamic range is You can run your camera in LCG 100 gain or HCG 300 gain modes and the dynamic range will not change significantly, but e-gain will change by a factor of 3
When is Low Conversion Gain Useful? - Stargazers Lounge HCG gain multiplier 'Normal' camera gain Zwo have tried to make it simple with having a fixed HCG gain multiplier and turning HCG on when the normal gain is set to 100 or above 😃 Some manufacturers have the HCG on off separate to normal gain, giving more control but needs more consideration to avoid conflicting settings 🤔
Confused about HCG vs LCG on OGMA AP26MC - Cloudy Nights Confused about HCG vs LCG on OGMA AP26MC - posted in Experienced Deep Sky Imaging: Hello, Im trying to find some starting points for my exposure times gains for my Ogma AP26MC monochrome - Basically a IMX571 clone Im trying to baseline as much as I can to the camera that most people have experience with, which is an ASI2600mm Looking at the charts, it looks to me that the ASI2600 is always
ToupTek ATR 585M, and more generally, what are the rules for HCG and . . . If you are stacking DSO images then High Conversion Gain (HCG) is better Basically it was an improvement that was added to Sony sensors at some point Astrophotography (the stacking of many images kind) also happens to benefit from it By using LCG you are just going back to the days before such technology existed
New to Astrophotography and confused about camera gain? This is "conversion gain" Some newer pixel architctures have two different readout transistors (for now pick one on consumer cameras, but some fancy cameras use both in parallel for high dynamic range) Typically these are called "High Conversion Gain" (HCG) and "Low Conversion Gain" (LCG) The ASI 1600 has only one pixel readout setting Other
Gain vs integration time - Experienced Deep Sky Imaging - Cloudy Nights Gain vs integration time - posted in Experienced Deep Sky Imaging: This has been rattling around in my head since acquiring a Risingcam IMX571C camera that, like the other versions, allows one to select either Low-Conversion Gain or High-Conversion Gain modes With the Touptek version (in contrast to ZWO) gain values range from 100 (not 0) you can set LCG HCG independently from the system gain
What exactly is High Gain doing for my CMOS camera? A camera with two conversion gain modes might have say ~14 stops of dynamic range at low gains in the LCG mode, but might still have say around 13 stops or so at a medium gain in the HCG mode HCG mode is valuable then, because it reduces read noise, with minor impact to your available dynamic range
HCG question - Beginning Deep Sky Imaging - Cloudy Nights HCG question - posted in Beginning Deep Sky Imaging: My Orion G10 doesn’t automatically switch to HCG like many other cameras do I can manually switch to HCG mode I thought I try it out with lower gain than I’m used to using while capturing images Is this a bad idea? Am I missing something obvious First captures are at Gain 10 and 10s exposures Doing an hour at 10s, 20s, 30s subs for
lcg vs hcg for narrowband imaging - AstroBin Hello fellow astro friends, i am a new owner of an touptek 2600kma (imx571 mono) and searching for some tips to get the most out of it If i am reading the sensor measurements right the only two useful modes to use are gain 100 lcg and maybe gain 100 together with hcg I am plan on using the lcg for my luminance and rgb imaging, coming from an imx571 color i will probably just use the same
The Svbony SV305C Camera (IMX 662 sensor) HCG Mode Jupiter . . . - Blogger In theory, when the HCG noise reduction mode is activated the noise floor will drop significantly and most of the dynamic range in the image will be retained which should yield much better color range and better image detail (true in both planetary and DSO capture modes) The SC311 wireless astrophotography camera!
