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.
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.

Help! I have a Skywatcher EQM-35 PRO GoTo mount for which I am unable to get the star alignment right, whether I use 1 star, 2 star, or 3 star alignment. I can get it polar aligned without any problem, but when it comes to star alignment it is way out. Choosing Sirius as the first star to align, the scope slews to the right general direction but about 20 deg. lower and slightly to the east of where it should be. The mount is perfectly level. I have checked, and double checked, all the settings, longitude and latitude ( N 50:41:46 W 3:13:53), Date in mm:dd:yr format, Time, Time Zone (0), Elevation (25m) and Daylight Saving Time (Yes). I am at a complete loss what to do next. I am getting close to chucking the lot into the sea!!! Before I do that anyone got any suggestions?
