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.

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.

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.?

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

I looked at the Atik/QSI site and they listed some retailers. I contacted one. They didn¡¯t have the camera listed, they didn¡¯t know the cost, and no idea if or when they might carry it.
So does anyone know the cost?

Very nice.
I love globulars.
So few?images get posted to this group these?days so it's nice to know that QSI's are still out there doing the job. Quality really does matter in the long run despite the break?neck pace of technical innovation.
My QSI690Wsg8?is still going strong after 10 years (fingers crossed) and the small chip works perfectly with my 5 inch refractor.? I have a ASI2600MMPro on a Redcat 71 and an AM5 (which is amazing) but have no intention of changing my CCD to CMOS while it still gets the job done.
Here is an example with M19 taken under Bortle 4 sky at the lofty?height of 294 meters above sea level from my backyard in the Blue?Mountains outside Sydney.
Cheers

Hi Bruce,
I've been travelling so just catching up. Lovely image of this cluster, with stars resolved right to the core. Also saw your previous tadpole galaxy image, which was equally very well done.

This is an image of M14, one of the bright globular clusters in the Messier list and located about 30K light-years way in the direction of the constellation Ophiuchus. I chose it as a "hurry-up" target right before the start of the summer monsoons in New
Mexico.? It¡¯s a very average globular cluster in nearly all respects with one notable exception: it shows a dramatic amount of reddening because of its location near the plane of our galaxy ¨C it has a galactic latitude of only 14 degrees.? This means our line-of-sight
to the cluster passes through the substantial amount of dust that's in the galactic disk.? This accounts for the dominant yellow star colors in the image compared to the more typical blue/white appearance of most globular cluster images.? The color balance
in the image was done using photometric calibration with foreground stars in order to preserve the reddening effect.?
The image was captured during a single night in June 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 4.5 hours.
Thanks for looking,

Re: QSI 700 series cameras in stock and available now.
thank you for the reply!
I hope the NINA native driver will have support for all the 6 series cameras out there! it has been quite a bit of a headache with ASCOM driver support on those.?
Any information on the tilt adjustment interface that was mentioned on Cloudynights?
looking forward to seeing some in depth reviews and analysis on the 7 series.?

A most interesting galaxy Bruce.? Very well done!

This is an image of Arp 188, the Tadpole Galaxy, a highly distorted spiral galaxy in Draco about 400M light-years away. ?The striking "tail" is a stream of gas and new stars that is about 280K light-years long. ?This tail is believed to have been caused by a tidal interaction between Arp 188 and a smaller galaxy that closely approached it. ?This interloper galaxy can be seen shining through the disk of its larger companion - it's the small, oblate, blueish object at the 5:00 position relative to the center of Arp 188. ?Models show that this galaxy probably crossed in front of Arp 188, then orbited around it and now resides about 300K light-years behind it. ?The field is littered with very distant background galaxies, many of which appear distorted or interacting. ?A Hubble image of a small sky area immediately surrounding Arp 188 revealed over 6000 such galaxies.? The rendition shown here is heavily cropped in order to highlight some of the structural detail in the target.
The image was captured during 6 nights in June 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.
