Indeed, and I use both. I was answering "isn't it just a Web page?"

Thanks, just added to my own strategy list

The SkySafari app. I use it to plan sessions and record observations.

All my observing records are electronic, and they may be convenient for searching, but yours are a joy to look at.

Apparently, Pluto is to have its planethood advocated by Web channel Pluto TV tomorrow: https://www.space.com/pluto-planet-status-rally-pluto-tv I've only become aware of Pluto TV recently, through an extended stay in a house with no broadcast reception, and it had already won my admiration by showing back-to-back Laurel and Hardy films throughout the evenings. Perhaps they will be proposing that the IAU replace the "has swept its orbit clean" qualification criterion with "has its own TV channel" instead.

Excellent haul, Paul. Glad to see that you're getting results out of the Vixen at last. Others have also reported the focus point of the 3-8mm zoom being 4-5mm away from their other EPs.

My favourite OC, nice drawing.

New or second hand? If the latter, make sure it hasn't been activated on too many other phones. I think it allows up to four. There are several members who have bought AZ70s solely to cannibalise the Starsense for other scopes, and they seem to think it was worth it. There's a thread somewhere on their efforts.

Louise, I'm not competent to offer advice on your imaging questions, but it's good to see you online again and I hope you find a solution that lets you carry on in your new environment.

Yes, the SW Freedom Find feature uses dual encoders, and you can move the mount manually (provided you remember to switch on the dual encoder feature in Synscan each time you set up - the default is "off"). However, once you do that, the gotos for the remainder of the session are generally less accurate, because the second set of encoders are located on the coarse side of the gearing. I've found that it is still accurate enough to locate objects within an optical finder, unless it's having a hissy fit. But I believe that the Star Adventurer doesn't have FreedomFind in any case.

Ah, you can't with that one. I have the same mount and scope, and I ended up doing what was described above - fitting a RACI finder to the existing shoe and pointing the viewing end upwards.

Do you know which mount it is? With some of the SW mounts, you can flash the controller with a different version of the software, to switch between left and right hand operation.

Looking forward to that one. Before the end of 2026, perhaps, with current weather patterns.

The constraint of the speed of light applies to inertial frames of reference within the theory of special relativity. The expansion of space itself is described in the theory of general relativity, and is not constrained in the same way.

When I saw the title, I assumed the point of the thread was that some members would find it quicker to list what they didn't own. Personally, I've not been going that long, and have only sold a few eyepieces so far.

Agreed, especially if you avoid the outer extremities. A steal at £54 for that quality. I find the 6mm to be a bit tight on eye relief, I'll be interested to hear how you get on with it.

I see you're UK based. Have you looked at any of the other threads on green lasers (including warnings) ? e.g. https://stargazerslounge.com/topic/374218-laser-pointer

These mounts seem a lot happier with some counterbalance, either a second OTA or some weights. It turns a lot easier on the Az axis. btw, I bought a SW 1.75" steel tripod for mine.

I love how this ship wouldn't look out of place on the cover of an old sci-fi magazine

This is why I bought the AZ-GTiX, which has a stated capacity of 6kg one side and 10kg total. My previous mount was rated at 5kg, but when I uprated the finder, got a 2" diagonal, etc. it was pushing it.

Stu has covered the essential points there. One lesser consideration is that if you have significant astigmatism in your observing eye, this tends to be more visible when using larger exit pupils. So, it can be preferable to obtain the same true field by using an eyepiece with shorter focal length but wider apparent field, the same tactic as for obtaining a darker background sky. As Stu says, it will be more expensive to get these wider fields that are well corrected to the edge. And it may force you into a 2" format.

This view from SkySafari gives an idea of its position and distance :

I saw it three years ago, just visible in my 6" Newtonian from Bortle 4.
