NGC 488 is a rather pretty spiral galaxy in Pisces, located about 90M light-years away. ?Its disk displays well-ordered, evenly spaced and tightly wound spiral arms with an unusual amount of subtle detail. The nucleus of NGC 488 has been found to be chemically decoupled, being twice as metal rich as the central bulge of the galaxy. ?This is usually taken to mean that it has consumed some number of smaller satellite galaxies in the past.
?
I found post-processing to be a bit challenging on this one.? The galaxy disk has low contrast and the spiral detail that makes the target so unique is quite delicate.? As a result, it takes some care to avoid making the detail look too "blocky".? I followed Bernard Miller's advice and got extra color data because the galaxy colors are also quite subdued.? The image was captured over a 6-night period in September-October 2024 using a 12.5" PlaneWave scope and a QSI-640ws camera at f/8 from SkyPi? Remote Observatories.? Total LRGB integration was 21 hours.

Re: QSI 700 series cameras in stock and available now.

 

Hello Rebel,

Our software team are looking into this issue and are in contact with the NINA about correcting the links older Atik SDK to stop it seeing the QSI camera.?

Sh2-170, sometimes called the "little rosette nebula", is a faint, nearly circular hydrogen-alpha region in Cassiopeia. ?It surrounds a small young cluster of stars that provide sufficient ionizing radiation to make the nebula glow. Stellar winds from the new stars and embedded dust in the hydrogen gas combine to create the complex visual structures.

The image was captured during 4 nights in September 2024 from SkyPi Remote Observatory using a 12.5" PlaneWave scope and a QSI-640ws camera at f/8 for a final HaLRGB integration of 16.5 hours.?

Re: Camera temp rising while reporting 100% - is the a defect?

 

The camera case is used as a big heat sink. The electronics will heat the case. As that heat warms the imaging chamber, I’d expect the temp to rise. Since your cooler is at 100%, maximally cooling, it cannot maintain the same temperature.

I’d run the cooler at 80-90% to leave some headroom for the cooling. The imaging chip is relatively low noise so the impact on images should be minimal.

Also the cooler will report 100% until the set temperature is reached. You should wait for temperature and % cooling measurements to stabilize before drawing conclusions.

I've had?the 6120 since it came out and find this temperature thing more of a big deal in summer. But in ALL cases, it settles down after a few minutes and everything works well. I was also concerned at first, but living too far away from the 'repair shop' decided to just watch it and see how bad it gets. As long as it settled down I saw no problem. Getting good images too. Still settling down to the real temperature. I see no long-term worries - yet.

I have a QSI 532 that I acquired, used, and used for some months. Then, on one occasion, after the temperature had been falling as you would expect upon initialization, the reported temp suddenly reversed and started climbing while the cooler was still reporting 100%. ?I contacted support and was told I could send it in for review, but finding a 683 on the market did not pursue it. ?Now I have a potential use for the camera, and in the meantime, I think I saw this same thing happen once with the 683, which works fine and is still in use. ?I suspect that this occurred in the late afternoon in a hot observatory building, and I wonder if there is some potential explanation for this related to those conditions that explain the problem. ?I would send it in for repair if that is needed. ?My astronomy club has a joint venture with a local university for a robotic photometry system, and the grant-funded AC2020 S-Big camera has been a two-year-long nightmare. ?The chip in this and the 683 are really well-suited for photometry. ?There is nothing on the market quite as good these days short of a significant 5 figure budget.?

Re: QSI540wsg

Hola Pepe,
?
Thanks, and were do I disable the ramp?
?
Gracias


Re: QSI540wsg

 

Hi Rainer,

This might be related to what you are experiencing, the way NINA controls the cooling differs from?Maxim. NINA has a cooling and warming ramp that governs the speed of the cooling system, depending on the camera control it might look?like the camera is not working properly. You can disable this ramp mechanism and leave the?cooling to the camera firmware (Maxim does this).

Cheers,

?

Re: QSI 700 series cameras in stock and available now.

 

I'll just add that I replaced the NINA's included SDK with the most recent Atik SDK (Aug 30th I think?), and the conflict between the Atik SDK and the QSI ASCOM driver went away. It still shows up as an Atik camera, but I can use the QSI driver. So that issue may already be fixed.


QSI540wsg

Rainer
 

Hi,
I just took the dust off of one of my QSI540wsg in order to use it with my Mewlon 250.
How do I reset the camera to factory default?
When connecting the camera via ASCOM to NINA it looks like the cooler is stuck. It does not activate the cooler anymore but it does activate it in MaxIm DL with no problem.
What could that be?
Thanks for any tip in advance
regards Rainer
