Greatly appreciate the responses. This all makes sense. Yes the lens is in great shape. I am not removing it to replace it. As to why, that would derail this thread terribly! I will post my results when I have found another person to assist with grabbing the tube.

Thanks again!

 

Sounds interesting 🤔

Thanks folks. I’m sure the sensor is dusty, so I’ve ordered a cleaning kit.

Take your time only use cleaning pad for one pass ,then use a second one.As said use blower first before you clean 

I think its a great image green star or not, nothing wrong with a bit of colour variety

The way I reconcile this is -  because we (our intellect) are part of existence (ourselves products of the "after the big bang") we are constrained only to know that existence or reality. The common answer is that anything prior to that is not a legitimate question as prior is a measure of time and time appears to be a property of existence (part of the fabric of our universe).  That leads to the entirely unsatisfactory "time",  and hence "prior", did not exist before the big bang.  That's so difficult for us to conceive because we don't experience time like that so our thinking is constrained.  

But as you say "hats off to them" - it's one thing to read about it, another to come up with it from first principles. They are genuinely gifted people.

Time is a measurement created by we humans,it is our way of understanding and explaining things around us including distance,if we were not here time would go on but unmeasurable 

Looks like a dust moat, your sensor needs a clean you can get a cleaning kit from a camera shop.

If you have sun you can use a ball bearing this will give you a point of light to focus on ,or a Christmas tree bauble will work and it larger .Set it 30 ft away 

The one I use most🤗

I think best way to use laser pointers is don't! Sooner or later you could have a issue with one.😵‍💫

Hi All,

I'm a new member, having just bought a a second-hand Sky Watcher 130P on an EQ2 with the standard 25mm & 10mm kit eyepieces and a Sky Watcher 7mm Plossl.

I have a couple of questions about the mount which I can't find an answer for, most likely because I don't know the names of these!

Anyway, what is the cam circled below used for?

 

And similarly what is the use of the grub screw highlighted below?

Thanks in advance!

Tim

 

 

I think the cam is a clutch to disengage the slow motion worm so you can move the mount by hand to your target .  Not sure about the grub screw as I can't see it clearly on your pic have you tried undoing it,if it is more than finger tight I would leave it alone . someone else my advise you more on what it's purpose is.

Whilst it may be physically possible to use the focus knobs, especially the fine focus (as it exerts a geared reduction) what you are doing is forcing the reduction gearbox in the EAF the wrong way with consequent very high torque which could potentially strip the gears. I have previously seen ZWO support on their forum saying it shouldn't be done and that manual focus should only be done via software or the optional hand controller. The reason it's harder with power applied is that the stepper motor exerts an electronic braking force.

Ok thanks for reply. I was under the impression that it was not possible to even turn the knobs. It was just so easy to turn that it seemed no harm could be done again thank for info I will leave it alone and use the hand control 👍

According to all I have read you can't use the focus knobs when eaf is fitted, when I have mine powered I cannot use the knobs, however when I have no .power to it I can focus with the knobs.Anyone else found thiis

From what I understand, the card slot is for Minolta creative expansion cards for plug-in modules that add more functions to the camera.

Minolta Creative Expansion Cards (1988 - 1997): Unlocking New Possibilities for Your Camera – photography (vitorfonseca.com)

Thank for the information very helpful thought for a moment it was some sort of storage card, original cost of this camera was  £500 +, a fair chunk of cash then,and now.

I came across this camera it is film but it also has a std slot with a card anyone seen this camera or owned one.

I feel like this is something that you never really see many threads on but is something I would love to have a go at at some point. Does anyone have any good advice for doing this? What kinda filters might I be looking at?

Well you can use mylar filter sheet which you fit over your telescope objective,or over tube if it's a reflector, probably cheapest option, or a glass solar filter again fits over your objective,you would have to get the correct size f.or your scope, or but most expensive a Hershel wedge.All this is for white light images.If you are thinking Hydrogen Alpha imaging be prepared to dig deep into your pocket

For what it's worth, the tuning knob was turned fully anticlockwise.

Ok thanks for that info.  I always say if you are happy with something that all that matters 🤓

I wouldn't take a phone image through a Ha scope as any sign of quality. The view through it is far superior. For a start, the sun appears deep orange, not pink. But the level of detail and contrast through the eyepiece is totally different.

The image is a crayon scribble compared to a Leonardo da Vinci masterpiece!

I'll get it out and see what I can get with my DSLR,

I've had it for three years now, and it has been my most used scope by far. If I were allowed just one scope, the Daystar would be it.

There has been a lot of talk of the variable quality of the quark that goes into it, but as far as I am concerned, mine is good. I haven't looked through any others, or any other Ha scope for that matter, so nothing to compare it to.

As an entry point to hydrogen alpha observating, I have no hesitation in recommending it.

 

Thanks for reply, as I said I have same scope probably like you for 3 years.i haven't used it much, a bit disappointed with it, but having seen your image I'll get it out and spend more time with it.Think I may have been a bit unfair to it.🤔

Hi I have the same scope what's your opinion on it 🤔

What equipment did you use

3 hours ago, Adaaam75 said:

I did, which tells me my initial focusing was slightly off because I had to stretch the images more than I wanted to to get some sharpness at a cost of resolution. I'm hoping to be able to achieve better focus in future but not great seeing hampers visually focusing and my Bahtinov skills aren't great (apparently!).

Yeah I used to over sharpen when I first started as well as contrast, but you learn as you progress in processing.End of the day if you're happy with the images that's what matters.🤓

Guys,

Constructive criticism please, seeing wasn't great and I was fumbling through Registax and GIMP but I'm very happy with my first real attempts.

ASI 462MC through Sharpcap on a 9.25/AVX. No filters. Probably 2000 frames but loads binned due to poor seeing.

Please bring the honesty and advice...

Your right to be pleased with the images 👍 .Did you do much processing with them as far as sharpening and contrast ?

Great image,stars stars more stars, love it👍👍

Oh yes, but it is perfectly fine to stir the pot when you’re bringing up valid points. He does Quote Einstein and isn’t necessarily making anything up that is not already known, it seems to be a genuine conundrum, I wonder what will be discovered one day to turn our understanding on its head. If we become comfortable with a conventional value simply because another cannot be measured then we may as well throw the scientific method out the window. 

I think a lot of Utub posting,not all, most are very good, are click fodder

With an air it's easy, within the autorun section, you set to record flats, how many and set the exposure to auto and it will auto calculate the correct duration. Much easier than doing it manually.

👍👍
