Ngc 55

[xelasnave]

I started on this object with some luminance and blue but the weather has gone off so I stacked what I had (230 subs at 30 seconds) as I was curious as to detail...

Happy enough and hope that I get a chance to do justice to this object..yes its a mono image but I could not help colouring it in just a little

I tried to follow Martins tips but I am still learning.
Next week my new computer will be ready so I hope to get more data and see how it goes using the new machine with double screen so I can see better the results as I go.

Much better

Picking up some lovely detail there Alex well done!

Thank you gentlemen.

The seeing was perhaps the best I have experienced in years of dampness but I would like to give special thanks to Martin ( Startreck) for his help in general and specifically for his assistance with processing advice on the finer points when using Startools.

And I think it is worthwhile to recognise that ( particularly with this incomplete data set) a little " cheating" with Photoshop can help produce a result from incomplete data.

I feel adding a blue hue helped take the edge of the blandness of my mono image and some gentle use of the burn tool in Photoshop on the detail gave it a little 3d type effect...at least on my screen...

The pity was the data was gathered on the third night of imaging and after two days of little sleep I had to stop gathering data ( so tired I did not remember Asiair could have gone on a little longer with out me) at around midnight ..I just could not face doing just two manual filter changes and sadly gave up and went to bed...just another two hours of red and green I think would have seen a rather decent result given the quality of the seeing.

The major limitation of using the RASA with a mono camera is the necessity to change filters via a drawer. It really is impractical. I have to remove the dew shield, take out one filter put It away and replace it with another filter..now I am very careful but I notice my filters are becoming marked and "dirty" so care does not prevent degradation it seems.

I have removed the mono camera and replaced it with the OSC and will buy a filter wheel and place the mono camera on the 115 mm which is not exactly what I had in mind but I think a sensible compromise. Shortly the two additional Asiairs will arrive and with the change I will be able to run all three setups and sleep all night..hard to imagine really but it wont be long now.

Thanks again.

Alex,
That’s a great start with so much detail , Star field is great too , just grab some more luminance and then an hour each of RGB and you will have a corker of an image
Well done !!!
I’ll have to show you how to use SV Decon ( Deconvolution) it uses your selected sampled stars to access the atmospheric blur and corrects it accordingly based on your Star sampling and a few settings ( completely different to normal Deconvolution)

Remember to use Compose ( not Open ) in Startools for Mono L RGB data sets
Just load your LRGB separately DSS stacked data sets into the the correct Channels in Compose , choose “L, RGB” as your Luminance Colour , press Keep then Linear and then process as normal
Startools has some neat options like adding Ha to LRGB Galaxy images using the NB Accent tool

Best
Martin

Thanks Martin I am on top of most of that and cant wait to get on my new computer and try the new decon. tool.
Yes I load RBG and L seperate in Deep Sky Stacker and process each in Startools and then load in appropriate spots in compose..I love it.

Getting more data for NGC 55 is a mere dream with this rain...There are puddles everywhere making working on my projects really tiresome.

Alex,
Just to clarify
You load your individual DSS stacked fits file L, R,G,B into Startools “Compose” L RGB channels at top , then Process as normal ……
I read your description above differently
Sorry to be a Startools Policeman

Cheers
Martin
