QHY183c and a selection og spacers,

Looks like i am doing a Dark library until the weekend.

My favourite Gerry Anderson series,

cracking music and opening sequence, and ohhh Wanda Ventham(Sherlocks Mum),

It had been a long time since I'd processed narrowband data so I was very encouraged by the response to the image of Melotte 15 that I posted a couple of weeks ago - thank you for all the comments and likes which were much appreciated.

I was really happy with that image when I posted it but as I've lived with it I began to dislike that the central column of gas (that some call the dancing man - but I can also see what looks like a peacock in there!) was so yellow and it also began to look a bit blocky and unrefined.

Thanks to some great advice from @ollypenrice and @Martin-Devon I've done a couple of reprocesses and each time, I think, improved the result.  Now I still think @swag72's version sets the bar, and my rendition comes nowhere near matching hers but I've been over this data so many times that I am calling this finished.

I have, though, learnt so much processing this data (which is the same as before: 10 hours of Ha in 600s subs and a further 18 hours of OIII in 1200s subs) and it makes me want to go back and reprocess a lot of the other narrowband targets that I've never really been happy with!

Anyway, here is the reprocessed version:

Same kit, obviously, but for completeness: TS Optics 130 Apo; iOptron CEM40; Atik OAG with QHY5L II; Atik EFW2 with 5nm Ha and 3nm OIII Astrodon filters; Atik 460 ex.  Captured using SGPro and processed using PixInsight and PS.

Thanks for looking,

Ian

Trully amazing!!

I live in a Bortle 9 area and even on a dark moon free clear night i can count no more than a dozen stars in the sky.  I suffered terribly with OSC imaging, even with a LP filter and processing was a nightmare as my images were incredibly noisy.

However, recently i decided to go the NB route and a few weeks ago i took a 1.5 hour exposure of the veil nebula in HA and 1.5 hours in Oiii using a skywatcher 200p reflector telescope and ASI1600mm camera.  The resultant HOO image is below. ( The image with the diffraction spikes) Compare that with a 5 hour OSC image i took a couple of years ago from the same light polluted back garden, i used a Meade 80mm refractor telescope with an Atik 320e camera and Light Pollution filter. I would have needed to go to a dark sky site for a comparable image.

Galaxy imaging will still be a problem with the RGB filters, but at least the nebula images will be a lot better

 

What would happen if you put a EFW with narrowband filters on a OSC, would you get the best of both worlds or just no benefit?

External pressure tuner.
My main gripe with my Lunt was finding the sweet spot using the stiff pressure tuner knob whilst trying to see the computer screen at the same time. This should eliminate this issue plus it allow me to initiate and control solar imaging sessions remotely when at work.

 

i just use a laptop next to the scope when imaging so camera appears on the laptop on liveview.

This is taken over 4 nights, but some nights I didn't collect much due to cloud, short nights and Clamshell dome obstruction Now fixed) 

I decided not to waste any more time trying to reveal the Squid in Bortle 8, though I did do twice as much data on Oiii as the Ha with a fast lens.

In total:
Ha 12 x 600secs (total 2 hours)
Oiii 2 x 20mins, 2 x 30mins, and 7 x 15mins 3 x 900secs binned x 2 (total 4 hours 10 mins)

Atik460EX and Samyang 135mm F2 lens @ F2.8
Guided on HEQ5

Total imaging time 6 hours and 10 mins.

Unfortunately Roger has a tendency to go to sleep while he is imaging, so might not get the message.

Personally I don't think you have a lot of choice if it is all stuck, but to shut it down and start again.  Sounds like the camera might not even have cooled anyway if it's all getting stuck.

Just busy getting started , only just seen this, sorry.

Shouldnt do any harm shutting down  , its happened a while ago, just get up and cooling again as quickly as you can.

Roger

Welcome to the Toil and Trouble of Astronomy and nice to see you on SGL, any chance of a guided tour inside the Dome?

Now, look what appeared at my doorstep this morning. It was specially priced at 78€ as it was a customer return. Also, to continue with my good luck, even those are sold as barebones, the tech guys at the shop, forgot to take out a 4Gb ram and 60Gb ssd, that they probably installed to check it's working fine + w10 os. 😊

Imagine that I was browsing for a similarly priced decent industrial USB hub, when I came across it.

Its ok if you have the valid serial number for w10 in order to validate online,it may already be validated to the shop you got it from.

looks like what i bought recently but mine was £900 but it has a 1 TB SSd and a HD 2.5 TB with intel I5 processor and 32 GB memory.

I've fallen asleep and fallen off my observing chair several times.

The other night I nodded off whilst using binoviewers and got a rude awakening as I nodded and became very closely acquainted with a bair of BCO Orthos.

That smarted somewhat and well and truly woke me up but no real harm done.

Nothing to do with the wine?🍷

They said that they would realease a video last time, did they?

Roger

How about which targets are good for which filters ie the right combinations for various targets(maybe allowing us to choose 1 favourite target to be included)including , sub length , conditions, right scope for the right target , FOV.

This arrived today for my Astro mini pc as the 1Tb mechanical drive was running HOT! Still more than big enough for DSO imaging. 

I have a 1 terabyte ssd in my new pc when I say pc it’s about 3 inches square by 1 inch high!
