I used the SHO script for this one. Red= 100% Ha, Green= 20%Ha and 30% OIII, Blue= 100% OIII. Tweaked in Photoshop afterwards.

THanks Spongey, I will have a go with your work flow ans see how it comes out.

Here is a link to my master files https://www.dropbox.com/s/omfochapkz3l7ka/master.7z?dl=0

Pixinsight and Photoshop

Wow ! that is fantastic. Can you jot down your workflow so that I can try and understand how to improve? Thaks so much. Regards, Simon

Here is a link to my Ha,OII and SII data. I would be pleased for others to see what they can do so that I can learn from it. https://www.dropbox.com/s/dv1i2lklxmf87qz/NGC 6888.zip?dl=0

With OIII added.

15x 600 sec subs in Ha under a full moon and 4/3 seeing. Atik 383 and 10" Quattro and Mesu 200.

I have an Atik 383L 8300 sensor. Reading the above I think that I will play it safe and take new darks for my different exposure legnths.

Do I need to do darks for every exposure legnths?

In Pixinsight can you make produce a Master dark in Batch processing without adding all the other file etc Flats,Biad and Lights? I get an error saying that they are missing when I just try and do Darks alone.

Do I use Average Sigma clipping or windsorised or just simple Sigma clipping ?

I have produced darks for every temperature that I image, 300-600-900 and 1200 sec. I thought that this is what was required 😀

I have cosmic rays in about 50% of my darks. What should I do?

I have just finished building my viewing platform. I found that the ikea bathroom steps with were ok but difficult form some of the elderly. The platform idea I found on the net and it works extremely well. It offers a much bigger and stable base to stand on and is also foldable. I have two rungs on it one for adults and one for kids. Attached are a few pictures.

did you flip the image horizontaly or is it as is with the phone and newtonian?

I flipped this image horizonataly, Is that correct for Newtonian with no diagonal?

Thanks Alan.

Attached is my Horizon file that can be loaded into Sky safari. Anyone is welcome to download it out of curiosity

Fantastically well explained and put together. A great reference narrative to understand easily the basics of the Cosmos. I can't imagine the work and time that went into creating this . Thank you for sharing this masterpiece.

I am currently using the old version of the Asi 120mm usb2 How much better is the ASI 174 regarding image quality? Is the image quality better on the newer ASI 120 usb 3?

I have given up on the pxp model as I have quite alot of cone error. I just do a blind solve and offset init before I start imaging and get good results.

double check that you have no cables snagging when slewing

When doing the "offset init" remember to make sure that you tick the correct box "west or East" depending on where your counter weight is.
