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.
Just a quick question saw a previous post on here for the x-cel eye pieces vs the BST Starguiders was looking at getting a 25 mm and a 10-12mm but would any one reccomend a zoom lens 8-24mm are these any good? If so any particular make I should go for instead of the starguiders or should I just stick to my original plan of getting 2 starguider eyepieces
Got a SkyWatcher Heritage 130p flextube dobsonian recently as my first more serious beginner scope and after some nice early shots of the recent moon as expected it's been cloudy in the UK since so I've been doing more reading up and of course splashing out the rest of my birthday money on some upgraded glass using lots of advice on here and other forums to guide me. So far it's all mostly been 2nd hand ebay finds and I'm reasonably proud of my collection and cant wait to get out and play more...
5mm TS Planetary HR
6mm Skywatcher Ultra Wide 66°
8mm BST Starguider
10mm Celestron stock
12mm Celestron Omni Plossl
15mm Vixen NPL
20mm Vixen NPL
25mm Orion Sirius Plossl
32mm Meade 4000 Super Plossl
Celestron Ultima SV 2x Barlow
Celestron Variable Polarising Filter & Moon Filter
I am however considering saving up or asking Santa for Baader Classic Orthos for the 10mm & 18mm gaps based on recommendations that they're superb. Or maybe the BCO 10mm and the 18mm BST Starguider.
Thoughts on the EPs so far and what will serve me best in future? Bear in mind i'm more interested at the moment in Lunar and planetary than DSO. Thanks all.
Hi, my current telescope is Celestron ExploraScope 70AZ, thinking upgrade to skywatcher heritage 130P(came with 25mm ajd 10mm EP) , if i do, can i use the eyepiece (4mm) and x3 barlow from my old celestron on the 130P?
One more question, i ordered a eyepiece camera Svbony SV105, i wonder what is magnification of this camera and how it work to change magnification.
