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.
Hi, I'm 100% new to astronomy, and I'm using a 7 year old eq2-mount telescope. After a few nights of awkwardly using the RA wheel I have to ask, aren't the RA slow motion controls on the opposite side to the eyepiece? How am I supposed to use them? Do I have to hug the telescope, or put the finder in the bottom? I also don't understand why one of the knobs' dial doesn't move when I move it around. Thank you very much, all help is appreciated. By the way there's a PDF by skywatchers I think, and that's all that came in the box as an instruction manual, the illustration is pretty accurate, my telescope is a reflective telescope
This is Celestron cg3 mount suitable for any telescope tube with vixen dovetail.
Load capacity is approximately up to 4 kg
Condition is used, but in very good shape.
It's comcompletely with 3d printed levelling plate, under tray for accessories, slow motion and locking knobs.
Mount was completely stripped down, removed factory sticky grease and applied proper grease where applicable.
I can post it by Hermes or DPD if you are happy to pay for postage.
I'll accept PayPal as family/friends or commercial if you'll pay the 3% fee.
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.
