Hi, I am pretty much new in Astronomy. Recently I have bought Meade Polaris 127mm telescope. The Barlow(2x) which Meade has provided is pretty basic. It gives pretty blurry view.
I have read few blogs and get to know that for 127mm, 2x-3x magnification is more than enough. Now I’m confused in its specs(element in it).
Wondering which one I choose, 2.5x Barlow 3 element or 2x Barlow with 2 element to get clear and crisp viewing.
Note on this issue: A suggestion from another forum seems to have found the problem but I'm not sure. It was suggested that after 3 hours my power tank was drained enough to inhibit the operation of the cooler. I attached my second (smaller) power tank and it seems to be working now. Of course the camera sat for awhile before I was given the idea that power was the issue and decided to try a test with a new power source. If anyone has any additional information or suggestion for me they would be appreciated. Original issue is below:
HELP PLEASE! ASI294 MC Pro Stopped cooling Also have an image saving issue. I'll try to give as much detail as I can:
Using APT with an ASI294 MC Pro - CAMERA IS NEW
Cooler is powered by a Celestron Powertank 17 fully charged connected using an Orion DC cable w/Auto Lighter Plug
Connecting via ASCOM ASI Camera 1 setting
Image Type RAW 16
USB limit 40
The camera is plugged directly into the laptop NOT a USB hub. I believe all my laptops USB ports are USB 2.0
No other software (such as PHD2) was running.
No other cameras attached.
Trying to create a dark library.
Cooling to -5C from room temp of around 25-30C
Camera and cooler were working fine for a couple of hours but I then ran into a snag:
I got a time-out message from APT saying "Still waiting image from the camera - 30s" also -
The cooling stopped working. (Red light indicating power is still on. Fan is still spinning.)
I'm also noticing that the laptop is making the chime noise it makes when something is unplugged or plugged in.
I tried connecting to the camera just using APT's ZWO camera setting with the same results.
Black level and USB speed settings were left blank.
Disconnecting and reconnecting everything seems to fix the problem only for a minute then I'm right back into the same problem. Changing USB ports does not help.
I tried using ZWO's "ASI Studio" and I did not seem to have any problems capturing images but the cooler didn't seem to be working. (Power was = 100%)
I tried using Sharpcap and did not seem to be able to do anything but I'm very unfamiliar with that software.
I went back to APT and tried doing 10 lights exposures of 30 sec each with no power to the cooler. Those went ok. I then connected the cooler. The cooler cooled the camera down to 23.2C then stopped.
Cooling Aid settings are
Timeout 120 (also tried timeout 300)
Disconnected the cooler and ran another set of 10 30 sec light subs. These went ok. Tried set of 10 10 sec darks without cooler. This also went ok.
I tried reinstalling the ASCOM drivers from the ASI site, restarted the laptop, restarted APT. Camera cooled from around 30C to 25.3C then stopped cooling (Red light indicating power is still on. Fan is still spinning.) I again started hearing the plugged/unplugged chimes from the laptop.
So right now this seems to be some issue with the cooling. Is the camera defective?
While I'm not computer illiterate, I'm not highly technical. I'd appreciate any help or advice but please put it into simple straightforward terms.

Just wondering what other people have experienced with this camera. I'm using a MacBook Pro, and want to use this camera with my Celestron 8SE. Primarily interested in the planets and the moon, but some deep sky images would be great if it's up to it.
It seems to be out of stock every where, but at $249 is about what I can afford to spend (no income at the moment). All of the research I've been able to do on this camera indicates it should work well with my set up.
I'm just curious if you have had any issues or problems. Thanks in advance!
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.
