Skywatcher 80 ED DS-Pro outfit including matched flattener and motor focus. Now only £350
This kit gives you a great introduction to astronomy and imaging, which is why it's so popular. You can see details over at FLO but there is:
80 ED Ds-Pro OTA (Objective Lens Diameter: 80mm, Telescope Focal Length: 600mm, f/7.5)
SW Eyepiece (2"): 28mm
2”/50.8mm Di-Electric Star Diagonal
Dual-Speed 11:1 2” Crayford Focuser (Backlash-Free)
Supplied with Tube Rings & Mounting Plate - please note there is a longer black vixen type dovetail fitted, not the fancy new green short one you will see on the FLO site
SW motor focus and fitting kit - I've never used this, hence it's not fitted (more details over on FLO)
Dedicated SW 0.85x reducer/flattener (see FLO for more details)
Aluminium Carrying / Shipping Case
The RRP is over £720, so grab a bargain while you can.
Collection from Nottingham, or DHL for £20 (within UK)
I just try to show the beauty of the night sky, and again the possibilities with a smartphone. There are already better applications at the google play to make the night lapse easy. At first I used the Gif maker pro. It's a good app to edit the frames, before creating video, but you can't save the videos in good quality. Now I use the TimeLab app (same developer, as Intervalometer app), in the editing it has not so many options, but with this app you can save the videos in 4K too, or full HD. This video is 360 frames (each 30 sec exposition at ISO 800) Huawei P10 monochrome camera, Intervalometer app, TimeLab app. Pictures taken in Kleinwalsertal, Austria 2019. 09. 23-24. (The video is full HD, I don't know, why, but it doesn't run continuesly on my PC, when I watch that back on SGL. I hope, on your monitors you can enjoy it!)
I scrapped all the Oiii and Sii data I previously took during a full moon (about 15 hours worth) and retook it all when the moon was a bit smaller at 76%. Ha was taken during 98% and 67% moon. All the lights were taken on the following nights: 12th, 19th and 20th September 2019.
Integration times, all in 600s subs unbinned:
Ha = 28.33 hours
Oiii= = 5.67 hours
Sii = 5.67 hours
The Ha data is really nice, and unsurprisingly the Oiii and Sii is not as strong (or nice).
I'm missing that (vital) step in my processing routine of getting the Sii and Oiii properly stretched to match the Ha, before combining. I dont really know how to deal with the weaker data properly. Any pointers would be appreciated.
What I do currently:
All the data is loaded into APP into separate channels/sessions.
The data is stacked and registered against the best Ha sub
This produces individual stacks of Ha, Sii and Oiii that are all registered
Each channel is processed with DPP in APP and then saved as a 16bit TIFF
Each is opened in PS
Stars removed with AA and any remnants removed and tidied up
I then open a blank RGB document in PS
I paste Ha into Green, Sii into Red and Oiii into Blue
Adjust the selective colour settings to get 'Hubble palette'
Adjust levels, curves, saturation until looks ok
All the Ha Sii Oiii data is then combined together in a single 'super' stack in APP using quality weighted algorithm to create a 'luminance'
That luminance layer is adjusted using levels, curves, and NC tools such as local contrast enhancement and deep space noise reduction (using masks to apply as required)
The luminance is pasted onto the above colour layer, and incrementally added using gaussian blur
Cropped and saved.
Here it is anyway I haven't intended on any more exposure time for this one, but will consider it, if the expert opinion dictates otherwise!
Hello, i am new to this forum, i made my account here because i need help.
So few weeks ago i ordered a USB to Serial cable to be able to Control my Telescope with my computer using stellarium.
It arrived today.
So i made my Star Alignment, then i plugged the cable to my Telescope and Computer, i installed the Cable driver and ASCOM Platform + ASCOM Celestron Driver.
I started DriverConnect.exe and put the Celestron Driver i downloaded, and did the properties informations ( had to tick on "Advanced Setup" and "Show All COM Ports" ) and i put "COM8" on "COM Port", then i pressed "OK" and then "Connect"
Create Creating device
Connected Connecting to device
Error System.Exception: Connect to COM1 failed, no Celestron scope detected
to System.Dynamic.ComRuntimeHelpers.CheckThrowException(Int32 hresult, ExcepInfo& excepInfo, UInt32 argErr, String message)

ReleaseComObject Releasing COM instance
ReleaseComObject Completed release. Count: 0
GC Collect Starting garbage collection
GC Collect Completed garbage collection
"Connect to COM1 failed, no Celestron scope detected"
In Stellarium i set-up everything, the plug-in and restarted the app, then added my telescope and i says it's "connected" but i can't find my telescope.
Celestron NexStar 127SLT
The Cable i bought:
Windows 10 Pro, GTX 970, 8GB Ram(DDR4), i7 6700 3.4Ghz
Looking forward for your help, thanks in advance,
Hello everyone, happy Tuesday.
First time stargazer here, I'm hoping I can get some awesome feedback from you guys.
my fiancé and I are planning on taking a trip to Great Basin National Park from October 25th-30th, we're trying to catch the new moon, we want to do some deep sky viewing but we're having such a hard time on knowing which kind of telescope to purchase. we do have a few must- haves on our purchase, but I wanted to see what you guys recommend and what your experiences have been.
we need a telescope that is portable
good for deep sky viewing
reflector vs. refractor
and almost, but not necessarily, easy to use (we have time to learn the ins and outs of it)
I apologize if its a lot, but trying to understand the jargon, as of now, is giving me a hard time
Cant wait for any responses!!
p.s. anyone ever been to Great Basin? what should we expect on our trip? its our first time going and first time doing any serious camping!!!
THANKS A BUNCH!!!
