    M31 I captured last autumn, even though I only have FL 420mm it seems like it still don't fully fits in the image. Astro Tech AT 65Q Canon700D Baader mod 5x120, 33x360 at ISO 800 Hope you likes it

    Recently it has looked clear but I have had trouble with very thin cloud, especially noticed while attempting solar.

    Wow what a great set of replies. I plan to come back to this topic whenever I have a frustrating imaging session or a streak of bad weather Thanks everyone for pitching in!!!

    Ah, I understand now. Did some quick reading up on the subject. There doesn't seem to be a simple answer to the best usage of these. To my eye, the red filters already seem to do a very good job of capturing fine details.

    The evolution includes the mount so that bit is sorted I've owned a C925 for a while. It's a lovely scope, quite a big beast and needs to be properly cooled and collimated to deliver its best. You will notice a big increase in resolution and brightness moving between the two. One challenge with planets currently, and for quite a few years to come is that they are very low from the UK. This means the advantage of larger scopes is somewhat muted due to the much thicker layers of atmosphere we are having to look through. You probably would not get a dramatically bigger image of Jupiter, but when the seeing is good, you should see alot more fine detail. It tends to be that you have to want longer for the moments of good seeing but the detail and colour seen should be much better. The 925 should be dramatically better on globular clusters, showing much deeper resolution of stars, and planetary nebulae such as m57 should also be much more satisfying. It will struggle on the larger clusters due to the long focal length and inherently narrow field of view. As others have said, there are much cheaper routes to more aperture such as a 10" dob. This would probably give you similar performance, with less cooldown required and more versatility due to the shorter focal length. You obviously lose the goto, unless you get a goto dob! It is always good advice to 'try before you buy', whether that is visiting a show room or a club or an outreach event. Take your time, but also don't get frozen with uncertainty. I hope that helps a little Stu

    Hi Alvin, Did you by any chance end up at Stoney Cross when you had your unsettling experience? Steer clear of the car parks at Stoney Cross as our observing group (Fordingbridge Astronomers) have had reports of such goings on in that area. There was a group observing regularly at Turf Hill but I don't know if they still do. Fordingbridge Astronomers observe at Hyde Common near Fordingbridge. Further west, Cranborne Chase has very good dark skies. I believe that there is also a group with an observatory on the downs north of Portsmouth. I'm in Poole myself so tend to observe on Cranborne Chase and near Swanage when I want a dark site. I would imagine that up on the downs around Winchester would be good and not too far from you. @Rob and @Jonk might have some suggestions in the more immediate area. Two of the problems with the New Forest are the Southampton Light Dome to the east and then the light dome from Fawley Refinery towards the south east. I grew up in the New Forest but I remember much darker skies that what I see now.

    I’ve been there with the 4 year old - although it’s my first scope that was bought with her in mind rather than an upgrade. If it had just been for me, no question I’d have gone for a 200p dob, but when I thought it through and took advice on here I realised that having motorised tracking was a must for anything that involved a “handover” between me locating a target and her looking at it. I went for a Virtuoso 114p which is a small tabletop dob with tracking but no goto (unless you add the Skywatcher WiFi adaptor). We used it a few nights before we got the power and tracking running and found it really frustrating, but once we could track it was so much better. I just don’t think a non-tracking scope is workable for people taking turns at viewing - especially when one is a small child. But I don’t think the 114p would be a sufficient upgrade for you (I’m planning to upgrade myself before too long). I have added the WiFi adaptor for goto but in fairly light polluted skies it’s been of little benefit really. My other big lesson from working with the wee one is how difficult it is for them to work viewing through an eyepiece. I’ve got a smartphone adaptor which can be a bit hit or miss and takes work to get properly aligned for planets but works well for the moon. Finding one that works with your new scope (or considering a camera to laptop option) would greatly increase ease of use and limit frustration. Good luck getting your daughter involved - my little girl loves looking at stuff and made us wake her at 1am on holiday last month so she could see Saturn. And if you haven’t found it yet, give her a look at some of the planet songs on YouTube...

    Below is a preview of nine phases of the eclipse as projected against an imaginary blue wall. The posted timings are in BST (UT+1). The events will occur at essentially the same times for all locations after adjustments for time zones. The Moon altitudes are for London. The eclipse will not be visible from North America.

    Unfortunately there's a lot of well-meaning but totally wrong advice posted on the 'net from folks who don't really understand EQ mounts. You certainly don't need spirit levels for any of it, that's for sure! Anyway, as Steve says, with an accurately polar aligned mount, all you need to do is manually point the scope where the system thinks the first alignment star is, and then tell the system to park the scope. It's really that simple.
