OCL 991 as known as NGC 6250 is a young open cluster, lying in a heavily obscured region within the boundaries of the next inner spiral feature. There are several arguments which suggest that the cluster is associated with the prominent dust cloud seen to the east of it.
This image data is thanks to the Courtesy of Jose Joaquin Perez a Moravian 1600 CCD camera, I decided on this project on the bases that it was difficult tp process given the large volume of stars in the region.
Processed in Pixinsight, I took quite a long-time using Blink and Cosmetic Correction going back and forward checking the stars and eliminating the highest level of hot/cost pixels possible and any imperfections. Then I started with WBPP
Overall Workflow:Processing Phase- WBPP
- Nomalization Scale Gradient
- Imageintergration
- DBE on each Filter
- Color (RGB) Combination
- Colour Calibration or PCC
- Denoise TGV and MLT – EZ SCRIPS
- From STF to Histogram Transformation
- SNCR (80%)
RGB Non-Linear Phase- Star reduction (EZ Script)
- Star Reduction/Roundness Morphological Transformation (does a more reduction!)
- Do a star mask
- Then a MT
- Star Net-Clone Stamp
- Color Mask the image
- Color Curves the image
- Retouch Noise Reduction
Luminance Phare(if its form taken image , not extracted)- DBE – Luminance as per RGB
- Deconvolution -EZ Scrip (for sharpening)
- Curves Transformation to bring out overall brightness-slightly
[*]- Lum De-noise (Mask) MLT-TGV – ACDNR)
- Linear Fit on RGB with Lum

Ha Blending with Luminance (Super Luminance)[b] [/b]
- Use HDRMT with Pixel math and Channel Combination
- Do a HDRMT to both images (Ha & Lum)
- Do a Pixel Math to bend each one, I prefer a higher % to the Ha rather then Lum (especially as extracted one), in the region of 80 to 20.
- Do a LRGB combination

LRGB Combination- LRGB combination
- Ha Blinding, using Bling Script to combine it with LRGB
- Image Enhancement
[*]- Use Range Mask or GAME script to localize Ha
- Enhance Contract (Local Histogram Equitize)
- Final Color Adjustment
[*]- Curves Transformation
- Color Saturation
- Foreground Brightening (Gamma Enhance – will increase brightness but not increase noise)
- Background Darkling
