Skywatcher illuminated reticule eyepiece. It has a red crosshair pattern. I think it’s 24mm rather than the newer 12.5mm models. Great condition. Looking for £35 including postage from France. Thanks.
The Carina Nebula is a large complex area of bright and dark nebulosity in the constellation Carina. It is located in the Carina–Sagittarius Arm, about 8,500 light-years from Earth. Pro Dataset @telescope.live Telescope: ASA 500N Focal Length: 1900 mm Mount: ASA DDM85 Camera: FLI PL 16803 H-Alpha: 3x600s OIII: 3x600s Bicolour Processing: Pixinsight
Not sure what topic to put this in but I've been struggling with deep sky stacker, because of my optlong ccd light pollution filter most nebulas come out one shade of red, for example the Monkey's head nebula, see attached example. Dumbell and ring turned out as seen online and Stellarium. All 3 images were taken with a rct f/8 and a canon 600DA. I've never tried these objects without the filter as I got new equipment and this is the most active I've been in my hobby for many years. I'm not spending hundreds or thousands on software so preferably if i can get the correct colour on these with dss or some other free/semi free software that would be great. Thanks
I am currently researching which setup to purchase as my first proper scope (once they are back in stock).
I thought I had settled on the Skywatcher Explorer 130ps AZ GTi but then I saw the Skywatcher Star Discovery 150i for just a little more money.
Could anyone please tell me the difference between the 2 OTA's (other than the different aperture size), and also the difference between the 2 mounts?
I realise that the AZ GTi can be modified to run in EQ mode whereas the Star Discovery can't.
Can the Star Discovery view all the way to the zenith or does the OTA catch the mount or tripod before it gets there?
I've been trying to image a couple of galaxies per night, one pre and one post flip. On early Saturday morning at 1:30am I changed over to M82, and acquired 63 x 3 mins subs, OSC, totalling 3 hours and 9 minutes of data.
Camera: ZWO 2600MC at -10 deg C, gain 100, offset 50
Telescope: Skywatcher 250PX (blue tube), 1200mm F4.7
Mount: Mesu e200
Guiding: ZWO OAGv2, 290MM, PHD2
Software: APT for capture, APP and PS for processing
I havent really had a chance to get much use out of this camera since I bought it in December, and I havent processed many OSC images before. I've a bit of work to do, but still very happy with the quality of the data for just 3 hours of integration time. I would like to add some Ha to this, but purposely didnt bother during the recent clear spell, as it was moonless nights and I gathered some broadband data on other targets instead.
