Thanks guys. I'll look into the 32mm.
I'm still learning this mount and want to persevere with it before just sending it back, you know, in case it's me doing something not quite right. I do take my time with levelling and alignment as mentioned and recently have had some objects in the FOV, and I'd hope the wider field of a lower power EP would turn that some into most. That'll do for me for the time being.

However if you do a few things during the alignment procedure it increases the accuracy of the Go to substantially. 1/ Ensure that your tripod is accurately leveled. 2/ On the first star alignment try and ensure that the last two movements are with the up/right keys. 3/ When selecting your second star choose one to the right and higher than the first and ONLY use the up/right keys again to centre the star.( if you overshoot slightly, allow the earth rotation to bring it back) 4/ If possible use an eyepiece with an illuminated reticle to centre the alignment stars,
By doing these steps I can use a 25 or 15mm eyepiece and my targets will be in my FOV
Thanks for this tip - I'll have a go as I am having difficulty with this mount

MMm. Another good idea. The double shoe thing may be a bit bulky and I am not sure if one side would interfere too much with ep area. Not seen the Rigel in the flesh. I have a telrad on my sct which is big. Too big for the ST. The rigel always looks a bit skyscraperish to me. I don't suppose you have a pic of it on your ST102 do you?

I have the same scope and focuser. I use a Rigel plus an Astro Essential 9x50 90 deg finder scope. The Rigel took some getting used to but is excellent and I would recommend one as the space it takes up in the scope tube is really small

It looks to be the same OTA as the one that they supply with the AZ GTE mount which as mentioned above has a small dovetail bolted directly to the tube

Thanks everyone. I don't think it will work for me as I won't be able to get enough focus extension - worth asking 🙂

Generally the biggest problem is that they aren't very well corrected at the edges due to the short focal length so you get a lot of fuzziness and coma from at least 50% out. I toyed with this a few times too but in the end decided that a pair of binoculars worked out better all round in most circumstances
Thanks for the reply. I have seen some imaging done with just a basic guidescope and it was OK. If it will work in principle I may give it a go. Plus I could useit as a better findertscope for my main telescope 🙂

Hi all. I was wondering whether is would be sensible to use a guidescope (or finderscope with 1.25" eyepieces) as a small grab and go telescope. I have basic 90 and 45 degree erecting diagonals and a load of eyepieces. I would like to use a photographic tripod or monopod with it so would need some way of mounting it to a quick release plate
Regards
Richard

I have the same scope on an AZ GTI mount. I have a cheap 90 deg erecting prism to replace the 45 degree that came with it. Might upgrade this at some point.
I bought BST Starguider eyepieces giving a good range of magnifications :-
3.2 156 5 100 8 63 15 33 25 20 I did have a 32mm but found I wasn't using it as I also have a upgraded finder scope that gives me x9 magnification and the 25mm BST gave me 20x.
If you want to limit the number of lenses I would keep your 25mm, and get an 8mm BST with your barlow initially
Happy with the BSTs and have used the 3.2 recently for Jupiter. As has been said it was low in the sky and seeing was not ideal but I was reasonably happy with what I saw.
I have spent way too much upgrading my scope and probably should have bought something better from the start but I have enjoyed the process :-).

With the camera, if you remove the diagonal from the visual path, I doubt you'd have an issue with any extra length added by the filter wheel.
Thanks,I'll give it a go

ZWO 5x1.25" manual filter wheel is the best one around for about £65 I think. There are generic ones under different brands from China which are much the same. I would avoid the very cheap 3x1.25" China ones.
I have seen those in various places. Just wanted to be sure that I would not have a focus issue. I guess I could get one from FLO and return if it isn't suitable

Hi all
I would like to get a cheap manual filter wheel for at least 5x 1.25 filters.
I currently use a SW ST102 with BST Starguider eyepieces.
Can anyone recommend a filter wheel setup that they know will allow me to focus correctly with these eyepieces.
Also I would like to be able to focus with a T2 adapter and camera wirh the same filter wheel - although this is not a deal breaker. I have had issues with 2x barlow and camera not allowing focus.
Thanks

In Southampton too last night. Clear sky but raining. It was a great sky though while it lasted.
And North Wales 🙂

I bought one of these for mine.. Cheap, decent quality. Dont expect to be able to run over them with a car But my Startravel 102 does great for basic protection and lugging it around.

Looks like the one I saw on amazon

Thanks all. I will try to find an ED80 case. If no luck I'll keep looking for something.
Cheers

I have a SW Startravel 102 and am looking for a suitable hard travel case. It needs to be able to fit the OTA and prism only so about 60cm x 15cm internal.
Does anyone have any recomendations for a budget aluminium style travel case.
Cheers
Richard

Thanks for the video. Will take a look when I can and hopefully it will motivate me to get out a bit more in the summer/shorter nights
Cheers

Astro Essentials do a replica of that, also at First Light Optics and I've had it about 6 months and find it very helpful on my WO Megrez 72 so go for it!
I have this as well.;Been very please with it

If you're on a very tight budget then yes that will work.
Thank you

Thanks for the reply. Just trying to save a few quid by using what I already had . The AZ GTI arrives tomorrow so just looking at options etc

Would I be able to use a standard high capacity USB output powerpack with this :-

Yes, best you can do is search for images of planetary nebulae or super nova remnants over years to see how slowly it expands when observed from a distance.
Have a look at this for example: M1 expanding over years: https://www.astrobin.com/full/327338/0/
If you are really interested in transient phenomena on stars - these can also be "observed" - but it requires specialist equipment and approach. I think that @andrew s does something like that with spectroscopic observations - records how spectra changes over time for stellar flares.
That is an amazing timelapse of M1- thanks

I use a BST Starguider 25mm as my widest lens - this is with a ST102 though which gives me the equivalent of a x20 magnification
