So far all of my experience with CCD is the archaic ST2000XM and that's been almost two decades ago.

Important not to freak out until you have tested equipment properly :) images will always look riddled with non uniformities when stretched to such a degree.?
?
?
|
If so, that's really good news because I was really freaking out about it.
|
yeah, you¡¯re looking at a screen stretch. They look terrible in TSX, This is not Amp glow And your sensor is likely just fine
|
OK, I can do that and no, no calibration yet.
So far these are shots taken under the @Focus 3 command in TSX.
|
Are you looking at a stretched image inside of TSX to make this judgement?
Have you tried calibrating out your images yet?
If you want you can send a raw dark image (FIT or XSIF) to my email and I can tell you if it deviates much from my 6120's.

Hello,
?
I have a 6120WSG that has significant amp glow top to bottom (black noise to white noise) on image while setting up new observatory.
?
Bought used, first time I have used it.? Just using to set focus in TSX at the moment. Is this normal?
?
Thanks.

What a wonderful image.? I checked out the Hubble image in the Wikipedia article about this galaxy and I am amazed that you could get such detail and color with a 12.5" scope.? Congratulations!

Thanks for the feedback, guys.
@Peter - the target is a bit challenging because of the large dynamic range.? The core area is very bright while the extended disk and arms are quite faint and low-contrast.? But at least with a Dec of 70 degrees, it's in a good sky location for you. :-)

NGC 6503 is a "field" dwarf spiral galaxy in the direction of the constellation Draco. ?The "field" classification means it is not part of a cluster or group and is gravitationally alone, an unusual situation for a spiral galaxy.
?It has been dubbed the "lost in space" galaxy because it resides at the edge of a vast empty region of space known as the Local Void. ?It is only 30,000 light-years in size, less than 1/3 the size of our Milky Way galaxy.
The image was captured during 4 nights from June-July 2024 from SkyPi Remote Observatory using a 12.5" PlaneWave scope and a QSI-640ws camera at f/8 for a final LRGB integration of 16 hours.

That is a very sweet image Bruce.? Just lovely!

Very nice indeed, Bruce.
The Hubble image on line shows the central detail, but you have beautifully captured the outlying areas as well. Thanks for sharing, now added to my rapidly expanding 'must do' list, which is getting larger all the time due to the continued poor weather here in the UK combined of course with twilight Summer nights.
Cheers,
Peter

Found my issue.?
I recently installed a Celestron Dew Heater ring. When connected without a controller the ring is turned up to its highest temperature. As it is ramping up the streak appears, when disconnected and it cools down the stars go back to normal. I had a friend who had the same issue. I was trying to use it with an existing Hendricks controller I might need to purchase Celestron's controller.
Thanks for everyone's replies toady.

There likely to be a hair, web, grit, skin flake... on an internal optical surface.? Use a flashlight and a squeeze blower. ?It is probably on a filter, the reducer, the corrector, or camera window.??

Sorry, should have elucidated, not the streaks on the star images, but the overall vertical banding. Excellent images until last week.

Hi Peter,
That's almost certainly from an optical obstruction in the telescope field. Please check for any debris on the optics, or tree branches etc. in the field.

Terry

I've just started getting this on my 6120 camera. It doesn't disappear in calibration shots. Is there an electrical problem somewhere??

Terry,
Thanks for the reply. The object was near zenith and the corrector plate was clear. This is a permanent setup and the camera was moved between sessions. Maybe there¡¯s something further down the optical train. It was late so I¡¯ll do some digging today.?
Regards,
Pete

Hello David,
We're very sorry about this, we are doing our best to keep our dealer network updated. Woodland Hills and Cloud break Optics in the US, have the new cameras on their websites already as well as several others world wide.
Please be assured we are looking to get the cameras on all of the dealer websites.?
Thanks
Vince
