Aaaaargh - you just spoiled my day by mentioning the RC that I had !!!! The very mention makes my blood run cold 😉
Happy to run images through CCD for you as often as you wish - just PM me and I will give you my email address to save cluttering up the forum.
Good luck!

Welcome to SGL. Cracking wee scope.
The light nights gives you time to make a light shroud for it out of a yoga mat etc and the fettle the focuser by adding a few wraps of PTFE Plumbers tape around the threads of the focuser to remove any slop and give a nice smooth action.
Enjoy it! Mine is my most used scope.

I have used the Atik EFW1 (no longer made) EFW2 and currently EFW3 with 7 x 2" filters - all of them have performed flawlessly.

May I ask what camera and lens you were using?
Canon 1100D and a Samyang 14mm for the Aurora and same camera and a 400mm lens for the moon.

I have heard about the 500 rule and the 300 one but I don't know if you are talking about doing this with a modified camera or not.
These were taken with a standard off the shelf Canon DSLR - not modified. A modified camera could have been used - the moon picture would probably look sharper and the Aurora just the same.
The 300 rule still applies whether the camera is modified or not.
Ευχαριστώ 😉

I don't think I'm going to buy a tracking mount since they are pretty expensive and I don't need it yet. However am am looking at different telephoto lenses.
There is a thing called the rule of 300 for cropped sensors. (Rule of 500 for 'full frame' cameras)
Divide 300 by the focal length of your lens and that gives you the maximum exposure time you can use without getting too much star trailing.
EG a 14mm lens on a crop frame sensor = 300/14 = 21 seconds exposure
When you start looking at telephone lenses it drops rapidly.
EG 1 200mm lens on a crop frame sensor - 300/200= 1.5 seconds
With a long lens on a fixed tripod the sun (WITH A SOLAR FILTER!) is a good target and there is always the Moon.
The advice that Carole gave you is good quality advice and is maybe worth a second read.
You don't say where you live - if its well North the Aurora is also a target.
These image were taken with a simple DSLR on a fixed tripod IE nothing fancy. But you will soon want some form of tracking mount.

Of course, it's one thing to have an immaculate calibration, and very worthwhile, but quite another to expect people viewing your images to be seeing them as you intended!!
I am used to that - no-one has ever thought my images are as good as I think they are!! 😉
I am keeping my eyes open for a Spyder5 Pro then at least I cant blame screen calibration.

Thanks Alan and Julian
I will have a play!

Thanks Alan
Its my two monitors hooked up to my main PC that i use for image editing that really need doing - I will have a look to see if they have seperate profiles. They are identical monitors but an image viewed on one then the other are considerably different. I couldn't find any info on whether or not the Spyder system can handle two monitors on one graphics card.

Yes, but you must use Colour Management from the old control panel, it will even allow you to calibrate printers etc....
Thanks Julian - found it!!
Subtle but noticeable difference and looking at the same image on my different screens it now looks very similar.
Probably not as good as the Spyder kit but better than it was.
Many thanks.

On the (excellent) Zoom meeting last night hosted by FLO the presenter talked about calibrating screens so that an image looks the same on any calibrated monitor.
It makes good sense and I am surprised that it hadn't occurred to me before now.
The bit of kit suggested was the Spyder5 Pro and it looks like it has been superceded by newer models.
I run two monitors from a single graphics card - does anyone know if I can calibrate these two screen independently??
I have emailed the manufacturers helpline but thought I would ask the collective wisdom.

That's suspiciously close to a boats sprayhood mounting foot. I am back at work on Weds and I will have a look to see what the sizes are. I guess marine grade stainless won't be an issue?

That's great! May i ask how you did that? I'm afraid I'm only a beginner in Stellarium.
There are many videos on YouTube etc and this is a good 'how to'.

The main difference between an Astronomer and an astrologer is about 100 IQ points 😉

Or you could create a photo realistic landscape in Stellarium then you can see at a glance if something is visible or not?
See attached - it tells me that at 0100 tonight Saturn will be briefly visible above my polytunnel - and it was last night - absolutely spot on. It also allows you to change the date and month so you can see what will be visible and when.
