Scosmico

I knew it was in the realm of possibilities, but nothing prepared me for last night. A combination of solar storm, new moon, clear skies and no light pollution delivered jaw dropping aurora displays.  Certain times I was actually looking overhead and southwards to see the display. Memorable! Spaceweather.com tells about auroras seeing as south as 29N. First time I have seen red auroras. They were so, so bright, deep, and lasted continuously for hours, full display of colour and structures with the naked eye.

It is really nice to have followed this sunspot. Its flares and the end results: 

End results seen from 51N

It remind me a big floater 

Great time to observe the sun. Amazing views on white light.

The star field is out of stock, but this one 102mm is. Very good on visual.

Last night it was easy to find it.  Bright coma. Hints of the tail averted vision just as the comet deeps under the rooftops. Had to pump up magnification to blacken the background. 4" frac f7; 9mm

Lung, If you want to embark on this hobby, something that was really valuable to me, in terms of eyepiece, was to learn how to differentiate a standard eyepiece from a good one. And no eyepiece gave me more understanding about contrast, sharpness, than  orthoscopic eyepieces. They are in the low budget spectrum, not because of the quality but because of the limited field of view. They are great for long focal length telescopes delivering a sharp planetary views. That is my advice about what type you could go first. All tips given before are very good.

Good luck.

Great views today. I could not recommend more. Also seen with eclipse glasses.

HAve you gone there already? How was it?

Just want to confirm the smoth service from RVO.

I bought my RVO Horizon 102 ED Doublet Refractor OTA and it was delivered very quickly as promised, no hiccups.

Excellent.

Thanks.

You have to start the search from within whatever sub forum you want to search

That is the point, I don't want data from the subfolder but the main folder.

In the 'app' version, when you start typing in the search box there's a drop down appears where you can select "this forum" or "everywhere" etc.

Just go in to the section you want to search and select "this forum".

In the pre 'app' mobile version the option was there somewhere too and I'm sure the full browser version will have it somewhere too, maybe in some advanced search options, but usually searching while already in a section would just search that section I think.

HTH

Same problem, in this folder means all sub folders are included.

When I do that all results from the subfolder also appear

Hi 

How can I search in one specific forum, without showing results from subforums?

e.g. search getting started general help and advice without results from prime and tutorials

Yes, I believe these are all the same United Optics (Kunming) 4” F/7 doublet design (lanthanum and FPL-53): http://www.united-optics.com/products/telescope_326922/telescope.html.

Interesting, I have never seen the f6 version of them

Is the Starfield 4” F/7 = RVO 4” F/7 = Starwave 4” F/7 = Tecnosky 4” F/7 = TS 4” F/7?

Great offers on Google Play for Skysafari apps.

I have the ES 24/82. on my f5 dob it sits on the limit of the coma annoyance. It is a great eyepiece for rich field. I use it a lot.

Hi

Does anyone know where I can find these tiny screws for the AZ5 mount? 

I have not found where I put them. I think it is easier to buy new ones.

Hi, 

Which Telescope(refractor) retailers in the UK check your purchased telescope (e.g. collimation) before shipping?
