I'd also account for visual now as despite your current preferences, you don't want to make an obs that just squeezes it in for imaging but would not be big enough if you ever wanted to do a bit of visual. That said, a 300p on an EQ mount would lead to some 'interesting' positions for visual.

I have rebought 24mm Panoptic, 15mm Panoptic and UHC filter. That's about it really although I'd like to rebuy a 40mm Wide Field if one came up.

Latest iteration. Just sold a pair of 15mm TV Plossls and bought a pair of 15mm Panoptics. Added Lumicon UHC and Deep Sky 1.25" filters too as they came up at a decent used price. Just need to do a bit of observing now!

LOL Mike beat me to it.

If you are a general observer, zipping about finding lots of objects then I'd say a good AZ mount (AZ4, maybe AZ5, SkyTee or Giro type) would be best. BUT if you just enjoy solar system objects or spending a lot of time on objects and maybe sketching, a driven EQ mount is ideal. Subject to the size of the scope, I'd recommend a basic driven (non goto) EQ5 or similar.

You are entitled to your view Ben but did you read the original post?

Just had a wander down to where my obs will be and it's a bit better there. Tonight near the house was 18.85 and down where the obs will be 19.12 both at zenith so hopefully a worthwhile exercise for a number of reasons.

Just checked and it's 18.9 at zenith and 18.5 towards Manchester. Not ideal!

I'll know more accurately on Thursday if clear. I get a SQML from my birthday

I'd think for the stated purpose, the type of diagonal would make little if any difference and if you want a correct, upright image there's no option other than to use a prism.

Good for binoviewers and possible PST mod too. https://www.altairastro.com/Starwave-ASCENT-102ED-F11-Refractor-Telescope-Geared-Focuser.html?fbclid=IwAR1e-CwpYWNdm89ar_7UX2KgsSKh0LOpIFqN6cwggdXHIKRa4W8L_VNggt8

There already is one https://www.firstlightoptics.com/pro-series/skywatcher-evostar-100ed-ds-pro-outfit.html That said. I think the f11 is better equipped and finished.

Loads sell on ebay and online generally e.g. http://www.mocap.co.uk/pipe-caps.html

I was referring to Motorways LOL I have a 16" dob but mainly use my 12" and 120mm Equinox. Once I have my obs I'll be using the 16" more regularly.

You think that's bad, I can see the actual M56 (and the M67, M60 and if I try the M66 and M62) from where I live!

Yep, I have 7, 9 and 11mm and they are fabulous eyepieces. They work well in my scopes (FL 1840mm, 1600mm, 1340mm and 900mm).

I totally agree Iain. In fact it was a close choice between a new observing stool or a SQM-L for crimbo. I went for the former as observing mainly at home I'll get more use out of it. That said, it's my birthday next month ?. I am planning an obs and inside there, protected from ambient and neighbour lights, I'll definitely get better readings and my eyes will also adapt more. I am also going to make a more determined effort to get out this year to a darker site each month around new moon so this will also allow more remote readings too. Coming from a background of insect recording (acting as a County Moth Recorder for Cheshire for many years) I completely agree about the power of collated data and also urge people to submit their own data when possible and considered accurate.

I don't disagree Iain but at least this gives a decent idea of which places are worth traveling to and test with a SQM for future use? Otherwise you might end up wasting a lot more time. I may be wrong but do these stated measurements not generally reflect the best case scenario and in general the prevailing conditions won't be such so readings will naturally be lower on average than in optimum conditions?

Whilst it's never going to be as accurate as single or multiple SQM readings at specific times I actually think it's a fairly usable estimate as for most it seems to reflect average conditions or be just a little off. If you live in say a Bortle 7 zone and want to use it to try and find somewhere accessible and darker than where you are, I doubt a small difference in readings will matter. If you want to get serious about levels then I agree a meter reader would be a useful investment but as this is free and you can get a rough idea of 'the world's' light pollution from the comfort of your armchair I think it does pretty much what it says on the tin.

In fact on my laptop, the box comes up every time you double click or single click anywhere

I did it on my phone as follows. Click the link and then keep double clicking to find your street / house (like Google Earth) I then double tapped on my house (well, where my house is) and the box pops up.

Just a bit of advice. Make sure you obscure your detailed coordinates. Don't want to advertise expensive kit in gardens unecessarily ? There are some lucky people ? I am hoping I can build an observatory at the end of the garden and hide myself away from lights / face East which should give me a shot ?
