Hi all
I'm a newbie here but not totally new to astronomy. I've had a telescope since I was a teenager (over 30 years!) and only ever had 1 telescope - a Tasco 40x40mm reflector. I expect members my age are familiar with it - thin and white with a thin metal tripod and a push and pull focuser. It's still functional at more than 30 years old although the thread on the eyepiece is worn so the eyepiece falls off regularly! I've only ever used it to look at the moon, Jupiter and Saturn and that's always been good enough for me. Now I have been thinking of getting a new scope. I have a very limited budget and so I am wondering whether I will get any significant improvements on what I can see.
My earliest memories of the Tasco from childhood were that I could see the rings of Saturn as a line across the circle of the planet. Having rekindled my interest in the last few years, I have started to use it again, and nowadays, when Saturn is visible, I can clearly see the rings 'as a ring' and the gap between the planet and the rings, which I don't remember seeing as a kid.
Vieing Jupiter I can usually see about 4 moons.
I've heard that the Skywatcher Heritage 130P Dobsonian is a good 'budget' telescope, and great for casual use, which is what appeals to me most. I don't want a telescope with complicated setup or one that takes up a lot of space. TheSkywatcher seems to fit the bill, and it also fits my very limited budget.
What I am most interested to find out is whill I get an improved view of the things I have already experienced? I have read some reviews that describe what you can see with this scope and it sounds like it's pretty much what I can already see. And it's maximum 65x magnification doesn't seem like much better than the Tasco's 40x. But will the wider aperture make a bigger difference than the magnification?
I'm also interested to know if I could use this scope for basic astrophotography - I have numerous cameras - phone cameras, compacts and DSLR's (photohraphy is my main hobby). I'm not talking about hour long exposures of dark sky objects, just what can be seen easily through this scope.
I'd love to know what people's opinions are, especially if you own or have used this scope. I'm also interested to hear recommendations for other scopes, but please remember I have limited budget and space. I know that an 8" or more is better and I would love one but they are just too expensive and too large for me.
Cheers

Hello all,
I have just joined and have been looking around, and putting in various searches to find the answer to my question(s).
I have already found some valuable information, but i can't find a specific answer to a question i have relating to exposure times.
I have shot the milky way several times before, from a tripod and a wide angle lens. I am aware of and understand the "500 rule" and that worked fine for me at first when i was shooting with my Canon 6D Mark II. When i moved over to the Sony A7III i noticed significant trailing using the same rule and that led me to the NPF rule (Via the photopills app incase people dot know).
I am heading back to Tenerife once again in about 6 weeks time and want to buy a star tracker so i can get some really detailed images.
I have done a fair bit of research and in principle, the whole thing doesn't seem to be too daunting or difficult.
I have purchased the Polar Scope Align Pro app so i can align Polaris as accurately as possible, i will practise putting the unit together and familiarising myself with the different parts etc, but it is the exposure times that i do not understand.
My best glass is the Carl Ziess 50mm F/1.4 Planar, the 18mm F/2.8 Batis, the Sigma 35mm F/1.4 Art & the IRIX 15mm F/2.4 Blackstone.
I currently do not own, nor have i ever used a tracker, and I cannot find any information relating to which aperture, ISO and Shutter length any of these focal lengths should or could be shot at.
Is there anything similar to the 500 rule or NPF rule that relates to using a tracker with varied focal lengths? or is it just a case of stepping the lens down for sharpness and then trial and error?
Thanks in advance,
Matt.

Hi all..
New to astronomy, bought my son a cheap telescope for Xmas and have enjoyed viewing with him so just bought myself a 250mm dob. Pleased to say it arrived today so started off with a bit of moon viewing. Must admit I've had a lovely evening!
Can see me investing quite a bit of time and money into this. Look forward to hearing from some of you members as time goes on.

Thanks in advance

Hi all, I'm hoping for a diagnosis as to why I'm seeing Jupiter the way I'm seeing it. I'm still a total newbie having got my first telescope at the start of December and managing half a dozen sessions since then. My scope is a Skywatcher Heritage 114P Virtuoso (114/500 F4.38).
When viewing Jupiter this morning (in Glasgow 6:30 - 7:30) and on a previous occasion it's been very bright and I've only had very fleeting hints of bands. I've attached a still and a link to a short video clip. I've got no plans for astrophotography but having a smartphone attached at times is helpful for my 4 year old daughter and the video clip is a fair representation of what I was seeing through the eyepiece.
This was viewing through a 6mm plossl and 2x Barlow (167x) but the image was similar but smaller using the 6mm alone. The scope was given about 45mins calling time (outside temp was -2)
I know there are a number of factors in play here, but the ones that came to mind are:
Should I be using a filter to lessen the brightness of Jupiter? Is my fine-tuning of the focuser not quite good enough yet? How much of the problem is the fact my table is on a decking that has a bit of shake. Will setting up the Virtuoso's motorised tracking ability improve the image? The "seeing" wasn't good enough? I've reached the limit of the scope? I could try a higher eyepiece and take it up towards the max 228x (although even at 167x the exit pupil is down to 0.7mm) Something else entirely I've not thought of. Any suggestions that will help me improve my viewing much appreciated.
Thanks
David
