OK, quick question - With a dome that has a push-to revolving top half would it be advisable / safe to open it up on a sunny day, point the dome opening at the sun and just point the scope (with the caps off) North so the sun should never track to it, in order to eliminate any fungus that has formed on surfaces? I realise the fungus would still be around, perhaps on interior surfaces that don't catch the sunlight, but warmth from the sun shouldn't affect the scope should it?
How often would you say this should be necessary to keep the fungus factor under control?
Similarly, should an eyepiece case be left open and exposed to direct sunlight, and should the eyepieces have both caps off in order for scattered UV to contact the glass surfaces? Will this be sufficient to kill off fungus etc (I read in a post that about 20 minutes should be sufficient)? Is there any danger from or to eyepieces so long as they are not directly pointing at the sun?
I have an eyepiece budget of $1,000 and would like your insights, please, to help me make the best choices.By StarGazingSiouxsie
My budget for eyepieces is $1,000.
I started off thinking I would get a Celestron eyepiece kit for about $200, for example. After trying a few out, I soon realised that I wanted eyepieces of higher quality. My mindset is that I'm investing $2,000 in my telescope, a Celestron 9.25 SCT, and I want to be able to extract from that scope the very best views that I can.
I'm looking to buy 3 eyepieces maximum (not including a Barlow)
Ideally - if possible - I would like to get eyepieces that I can use on both my telescopes, but my priority is toward the 9.25" as that is the bigger investment.
Both my telescopes have 1.25" barrels.
* Cassie - A Celestron Newtonian. Aperture = 130mm, FL = 650mm, FR = f5 Max useable magnification between 250x and 307x
* The Cubble Space Telescope - A Celestron SCT. Aperture = 235mm FL = 2350mm, FR = f10 Max useable magnification between 460x and 550x
I don't feel comfortable spending more than about $300 on each eyepiece
I want these eyepieces to last as long as possible. I try to look after thinbgs if I can.
Decent eye relief if possible
I will purchase a Barlow separately
Field of view - something 60% +
My observing will be probably 80% solar system planets & moon, 20% deeper sky objects
I'm not that in atsrophotogarphy. I have a little Celestron NexImage 10 with which I am hoping to make some videos and stacked images of Jupiter, Saturn and detailed imaging of Pluto ( )
I really just want the WOW factor right now. Enjoying the thrill of Saturn;s rings, tracking Jupiter's 4 main moons, detailed lunar observing etc.
So what would be your suggestions or advice, please?
I have been looking at the Tele Vue Delos & Delite range. The Nagler range looks nice but I'm note sure if I need 82' field of view. A bit pricey, too.
Explore Scientific's offerings are a possibilty.
What's the deal with zoom eyepieces? Does that mean you can have an eyepiece that will do the job, for example, of a 6mm, 7mm, 8mm and 9mm eyepiece all in one? Is there a trade off?? What's the catch??
Regarding Barlows, I was thinking of just keeping it simple and getting a decent 2x lens without spending crazy money. Something in the $150 range. Or would I need a high end Barlow to complement the better eyepieces I am hoping for???
Overall, I'm looking for 2 or 3 eyepieces and 1 Barlow with a $1,000 budget. Any thoughts, ideas, advice or opinions all gratefully received, thank you.
I'm relatively new to the whole telescope thing but have done my research and was fixed on getting the Orion skyquest XT8i or XT10i. By spending that much money, I didn't like the idea of purchasing it online from their website without seeing it in person (and not having the reassurance of being able to take it back) and looked for stores in the UK that would supply them. After plenty of research, it seems like they don't exist anymore and they are only in the US? Is this right or could anyone help me?
(I've looked at the Sky-watcher 250PX/200PX flextube skyscan goto but it is significantly heavier and the noise of the goto mechanism sounds like a table saw so that's put me off of it...)
Any help would be much appreciated,
Friends, I am back with a tutorial video on how to modify your Sky Watcher HEQ5-PRO mount or its American twin, the Orion Sirius EQ-G into a belt driven mount.
The benefits of converting to a belt drive is that you don't have to worry about Backlash. The procedure took me about an hour to complete.

TL;DR: are there any cheap ways, including secondhand, of mounting a 130P-DS for not-completely-terrible results?
I am looking to buy a telescope as a gift for a family member. I had in mind a budget of around £150-£200, and from looking at advice had almost settled on the Sky-Watcher Explorer 130P. But then I realised that there's a good chance that if they get into astronomy there's a good chance that my relative will want to do some photography, and would probably be interested in attaching their micro four thirds camera. I've learnt that the 130P is not great for this as you cannot get prime focus, so you need to look at the Sky-Watcher Explorer 130P-DS instead.
Great, I thought! It's a bit cheaper, but it isn't available in a kit with any form of mount. OK, I'll need to get one of those too...
Then I started looking at mounts. Oh my, those things crash through the top of my budget! Even the EQ2 mount on its own, when you can find it, is about £115.
(Given that you can get the spherical version of the Sky-Watcher 130 on that mount for £155 from FLO, that seems to value the OTA part at somewhere around the £40 mark.)
So, I'm after advice on whether there is an affordable way of doing this.
I've read enough on this forum and other sites around the web to know that the main recommendation is that the heavier duty the better. Something like an EQ3 or upwards. And that for AP a lot of people seem to view an HEQ5 as a starting point. But since I can't stretch to that, I'm OK with leaving it as an upgrade path for my relative if that's the way they want to go (or option for future gifts!).
I know that for next-to-no budget I'm not going to be able to give something that will get the best out of the telescope. I know that getting motors and whatnot to do the guiding that will make DSO photography possible is way out of the realms of possibility. What I'm hoping for is some sort of option that gives acceptable results. Usable rather than unusable. Limiting the results rather than destroying them! Getting this set up so that they can do reasonable observation at first, and maybe give a try at attaching their m4/3 camera to try photographing the moon. If that whets their appetite then mount upgrades can be possible later.
Since I'm planning on a new OTA, I'd be happy with going secondhand for the mount.
I've been trawling ebay, and see the odd thing like this come up:
To my untrained eye, it looks like there's an EQ2 mount on that, so I'm wondering whether that would do the trick. (Working on the, possibly faulty, assumption that if EQ2 is viewed by Sky-Watcher as being sturdy enough to supply as the kit mount for the 130 and 130P, it's probably up to scratch for observing with the 130P-DS too.)
Even that, at another £58 inc postage for the buy it now would be over my budget, but I'm wondering more generally whether trying to grab something like that to essentially discard the tube would even be feasible as an option if I can get one at the right price.
Or, of course, I'm open to any other ideas and suggestions that the forum might have.
Thanks in advance, and clear skies.
