Help please. Last night I purchased an old celestron c8 sct, 2000mm fl, f10 on a fork mount. The mount has no power cable so is pretty useless, but i brought it to defork the ota for planetary imaging and hopefully some small faint dso's. It was a reasonable price. Ive got a heq5 pro mount that i will be mounting it onto. The guy said it needs collimation. I know i need to mount it on a vixen dovetail but the bolt holes dont line up anywhere. Its as if someone has rotated the corrector plate housing around 120 degrees. Would it make a huge difference if i removed the housing screws and put it back so that the bolts line up, keeping the mirror and plate in the same spot on the housing bracket, or would i have to try put everything back separately in different positions and collimate everything from scratch. The picture at the minute doesn't quite get crisp so whatever has been done needs rectifying. Can this even be done by us regular folk? Any thoughts or ideas, instructions? I feel the plate could do with a clean and the primary mirror itself. I just want it as optimum as possible. And can a hyperstar be fitted to these older versions? Im literally starting from scratch with an sct setup. Also what type of camera would suit a scope with this focal length for faint dso's, i have a gp290c for the planetary side of imaging. Sorry for the bombardment of questions.

Not sure I am in the right place. Completely new to this. I have bought a Omni XLT 150 Newtonian telescope. I have followed the instructions on how to set it up (5 times!) and can't get it to focus. I've lined up (I think) the finder scope, point the telescope at the moon, and can't get anything more than a blur. Clearly doing something wrong. Anyone know how I can get this to actually work? Thank you, in advance. Pete Elverhoi
I'm matt from the UK, essex to be more accurate. I had a skywatcher 150p around 8 years ago and had some amazing moments with it, Jupiter being one of the highlights despite the 150p's declination towards DSO's. Unfortunately due to some financial problems at the time I had to sell it. Astronomy was a hobby I locked away to a quiet corner of my brain until my very wise other half helped me realise how much I missed it.
We have just bought a skywatcher 150pds as i want to focus on astrophotography this time. Its currently on a eq3 pro mount with synscan. Not the ideal mount, i plan to upgrade to the heq5 as soon as possible, but its perfect for me to learn and practise on.
We bought the scope and mount second hand in an amazing deal, coming with the coma corrector, all 3 sky panorama uwa lenses, the canon t ring adaptors and a clubman flight case for £700. Everything in perfect condition, although the mount has some stickiness and i think maybe some binding in the gears, so I plan to strip it down, de and regrease and reassemble as soon as possible.
Have only had the opportunity for a couple of hours viewing so far, during which I very unsuccessfully attempted to polar align and then 2 star align the mount, but loved seeing it slew. I did get some amazing manual visual observation on the moon, but was surprised that despite my previous experience with a very similar scope just how much I don't know. Am very eager to learn as much as I can and am very excited to be back in the hobby, as you can probably tell from my extracted and probably boring welcome message.
Anyone with any experience of this scope or mount with any tips or little known tweaks I would be exceptionally grateful for any advice. Or any tips in regards to polar aligning and star aligning, especially in a class 6 bortle or similar.
One problem I struggled with was gaining any focus on any lens I have while using the barlow lens. Am sure it is either my error or cheap equipment but I gained a very nice focus with the 28mm supplied lens and the panorama range but struggled gaining focus with the barlow and said lenses. After looking into this though I'm wondering if it was due to me not accounting for eye relief?
I look forward to meeting like minded people on this forum.
Hi everyone! So I’ve been lurking on this forum for a couple of months and thought it was about time I made an account as I’ve been back and forth deciding on which scope to purchase.
I only got into Astro a couple of months ago when I took my first photo of the moon on the night of the ‘flower moon’, with my Canon 700D. I don’t know why it had never occurred to me to try and photograph it, but I think lockdown prompted me to look around and notice the sky a bit more!
Since then I’ve been trying to get photos of the stars whenever there’s been a clear night (rare in Manchester anyway, plus my garden is Bortle 8 on pollution). I’ve succeeded in a few nice snaps but it’s time I invested in this hobby now I think.
Having never owned a scope I’m completely new to this so trying to pick something that isn’t massive (for storage purposes), that I can get a good view of the planets but mostly something where I can see and hopefully photograph deep sky objects from my garden if possible.
I’ve recently been looking at the SkyWatcher Explorer 130PDS or 150PDS, and want to spend £400 max. I’m leaning more towards the 130PDS due to cost, and based on some photos I’ve seen on here, although I imagine the 150PDS would be better, although appears to need a mount purchasing separately. I nearly went for the William Optics SpaceCat 51 at one point, then realised I was probably trying to run before I could walk!
Any help at all would be fantastic.
I am looking for a good app that I can use to edit the videos I take for processing.
Solely will be focusing on lunar and planetary due to setup limitations.
Anybody able to fire out any recommendations?
Dont mind having to pay for an app if it enhances the abilities of the app.
