  1. Tried to remember how to process stuff mostly :D I only dusted my kit off last night for the first time in 9 months!

    I did a quick stretch in PI and it all looked nice so moved to PS for levels/curves and a little color balance. Pushed vibration a smidge then back to PS with a starmask/star reduction.

    Nothing fancy and I'm sure others will do better but it looks really clean and nice data

  2. I finally got a chance to try this and it worked well with the MPCC in the draw tube. I then had two problems:

    1. The stock focuser kept falling down, I have just finished fitting my Steeltrack to test that later

    2. The guiding using the 1500 focal length was crazy, it just didn't work at all. I have reverted back to the ED80 as a guide scope for now

     

    As for removing the stuck fine pitched threads, I favour upside down on a rubber glove pushing down and twisting. Sometimes you need to pinch the corners with mole grips too

  3. This is an SHO version using Pixinsight and Photoshop

    I stretched each layer and combined into an RGB then, using Selective Colour, I adjusted a separate layer to boost vibrance which was merged to pull out detail of the nebula

    An agressive removal of red followed before some levels and curves then finished with a morpholigical transform which was selectively masked in

    I did crop a tiny bit as there was some noise on 2 edges

  4. It has taken me nearly 4 months to get enough data to produce this - NGC7380 or the Wizard Nebula

    The hydrogen alpha was taken over 8 nights throughout July with 4.5 hours of usable data. 2 multisacle median transform, a light one across the whole image followed by a luminance mask to push the background. Then a layer with the unprocessed image was used as a selective luminance (masked by selective colour to only affect stars) for some of the bigger stars. Ringing was removed with another layer with 100 on the contrast dial then masked this in round the edges. Registax was used to add some wavelets then a minimum filter in PS to recover the stars.

    I had to wait until September for some darkness and usable skies. 2 good nights of O3 data followed which gave just under 7 hours of data. I added 30 5 minute darks, 20 bias and 20 flats to this. The O3 was simply stretched and a star reduction was performed

    S2 was all last night, I got about 6 hours in total with a bit of moon to fight with but good enough to pull out a picture
