Hi, I have taken mono LRGB images of M51 with my new ASI1600mm-PRO.
I have a mix of 30s, 60s, 120s subs. 100 darks, and 100 flats for each filter. About 4 hours total.
I Used DSS for alignment and stacking, then Pixinsight for LRGB combination.
My issue is that i'm not happy with the colours, the stars all appear white and the background is strange.
I have attached the Aligned LRGB images.
Can anyone point me in the right direction? Thanks!

This listing is for my personal LRGB filters (Kayron from Light Vortex Astronomy). They are the Astrodon E-Series Gen2 LRGB 1.25" set. These are considered the highest-end LRGB filters money can buy, able to produce exceptional quality, colour-balanced images when paired with a good monochrome camera. For more information, please see Astrodon's website:
Please note that this filter set currently retails at just over £560 from UK suppliers, €660 from European suppliers or $540 from US suppliers. Payment is preferred via bank transfer but PayPal is OK with an extra 2.9% to cover PayPal fees. I'll cover postage to you via tracked Courier.
I welcome any questions you may have regarding this listing. Thank you for looking.

Following a filter size upgrade I have an Astronomik LRGB set of filters, 1 1/4 inch. Probably around 12 years old. Kept in a filterwheel when in use but they have also been stored for a couple of years in their original box when I acquired some Baader ones to match my Baader narrowband filters. No scratches or coating issues. I have tried to show this in the images attached.
Looking for £80 posted given their age.
Galaxies in Leo Hickson 44 is a group of interacting galaxies in the constellation Leo, also designated as Arp 316 in The Atlas of Peculiar Galaxies. Inverted crop of luminance: Equipment used: Altair Astro Hypercam 183v2 mono EQ6 Skywatcher ED80 N.I.N.A. used for capture and control, calibrated and stacked in Astro Pixel Processor, post processing in PixInsight with final color tweaks and watermark in Photoshop. NGC 3190 is the nearly edge on spiral galaxy in the center of the image, with the very prominent dustlane. Lower to the right is NGC 3187 a barred spiral galaxy. Above we find the hazy eliptical galaxy NGC 3193. NGC 3185 to the lower left is not a part of the Hickson 44 group, but is another lovely barred spiral galaxy. The distance to Hickson 44 is approximately 80 million lightyears. Total integration time is around 9 hours in a bit of a mixed bag of subs. 100 minutes of luminance. 153 minutes of Red. 150 minutes of Green. 141 minutes of Blue. I made a synthetic luminance by stacking all lum, red, green and blue subs for a total luminance stack of roughly 9 hours, but it stands to reason that the contribution of the RGB only equates to a little under 3 hours of luminance. I am experimenting with just shooting RGB and combining it as a synthetic luminance, it is probably faster to get real luminance in the end. But shooting this much RGB compared to what I normally do, made it a little easier to process I think.

Comments and criticism is always welcome!
