SkyTech L-Pro Max Light Pollution Suppression Filter
Used for about a year now and still in very good condition. really helped me out in my garden but now I've moved to tougher skies and need a slightly stronger filter. So it's time to pass this on to someone else.
Filter is in very good condition with no scratches on it. Used extensively to great effect. Cardboard box slightly tatty but to be expected.
Creates very nice pictures with good star colour retention and no halos. Horsehead is a HaRGB composite photo where the RGB was shot with this filter.
2" fitting (M48). Will come with outside box, interior box and of course the filter.

I've been having another crack at DSO imaging lately, and I've managed to produce this from 6 hours of integration:
I'm quite pleased with it but I'm very new to image processing, so I'd be incredibly grateful if someone wouldn't mind having a go at processing my data!

Messier 57 is is just coming into a position for a decent look around 11 30 pm. IT is a colourful object and I thought it would give me a good target with which to practice my colour developing in PS/Lightroom. I have read so much about how to produce a LRGB image from the four stacked/calibrated luminance, red, blue and green images, a lot seems contradicatory and some, when followed, gave me colour yes, but not as we know it. I am sure a fair chunk must be put down to me. Anyway, I now have a work flow which gives me colour, sometimes resembling what other people have obtained. Progess of sorts.
This images is based on 114s subs at gain 139, offset 21.

Messier 57 Ring Nebula in Lyra
NASA: M57, or the Ring Nebula, is a planetary nebula, the glowing remains of a sun-like star. The tiny white dot in the centre of the nebula is the star’s hot core, called a white dwarf. M57 is about 2,000 light-years away in the constellation Lyra, and is best observed during August. Discovered by the French astronomer Antoine Darquier de Pellepoix in 1779, the Ring Nebula has an apparent magnitude of 8.8 and can be spotted with moderately sized telescopes.

Since I am very new to this, I struggle a lot. Especially when observing planets and also recently deep sky objects. My telescope is an amateur telescope and its almost 11 years old (The telescope was re used a year ago). During summer of last year I took photos of Saturn,Jupiter and a month ago took photos of Venus and Mars. About 2 days ago I stumbled upon a new thing in the sky, (Unfortunately, I didn't take a picture). It definitely was in the Orion constellation as I had observed Betelgeuse and the 3 stars that were close to each other. After a couple of minutes later I saw 2 stars next to each other and another two which were on top of the other star, surrounding these set of stars were a blue-ish and grey-ish colour at the same time. I had done some research and many people told me it was the trapezium cluster found in Orion. I honestly don't know. Any ideas? Thanks.
Hi! I've recently acquired a new Astromodified Canon rebel XT and I've tried to take pictures of nebulas using it but I've noticed that there are these weird black artifacts that keep appearing in my images. Would like to know if anyone has experienced this before? Or are these dirt/dust specs on the camera, filter, and telescope glass? I've attached some of my edited and raw pictures for your reference. The black artifacts can already be seen in the raw image of the horsehead nebula and after stacking I think it got amplified. Anyway, advance thanks and I hope everyone's doing well.
