Sorry to gatecrash! does anyone one know the motor shaft diameter?

Hi Jamie.

The collimation is out, the point of light should be dead center.  I have turned the secondary mirror when cleaning my C11 and it always needs collimating I would try that first. Collimating is like balancing a saucer on 3 fingers and trying to get it perfectly level : ).

This is worth a read too telescope - What are the aberrations of an SCT? And how can they be eliminated? - Astronomy Stack Exchange

Your 80ED will have a wider FOV and will be much more forgiving, the optic configurations are different too.  

But for a big SCT on a NEQ6 those stars aint so bad  I think your scope needs collimating but thats probably all it needs.   Also check your backfocus using a Focal reducer on my C11 its 105mm FR/C to Sensor 

For me it has to be a hell of a night to get 'nice round stars' using a C11 XLT on EQ6 Belt modded mount but use it for what is good at, getting nice resolution on small galaxies and great planetary/lunar scopes.  The Edge versions are really the imaging scopes we're pushing this kit really to do something it aint that great at.  I stumbled into using mine for deepsky as I started with planetary imaging,  I use pixinsight to process out most of the defects in my images im getting really good at it : )

Hi All.

I have a ZWO asi071mc pro and will be using it on a C11 with a 6.3 focal reducer I have been advised that i will need 85mm BF from the back lens of the reducer, the issue is if I use the 85 mm measurement the vignetting is massively pronounced compared to a shorter BF length. Can someone point me in the right direction to a formula  that I could use to work out the BF myself. 

Thanks.

I have also looked at the ZWO ASI 071MC-PRO USB 3.0 Cooled Colour Camera but at a pixel size of 4.78 microns maybe a little bit too small for the C11,  I would go for the QHY10 but I have had problems with flats with my QHY8L and I have tried everything. short exposures, over 4 second exposures using dim light. Morning sky, evening sky ,white screen on TV, cotton over the scope, paper over the scope, adu from 9k to 40k, bias subtracted nothing seems to work  my flats always over correct or degrade the image in some other way! So this puts me off the QHY10 

I guess the Atik acis 2.4  is the way to go I  have looked at the Atik 383L + colour but this uses a Kodak sensor which I hear are nosier than the Sony offerings. 

Does anyone know if there is a supplier holding stock of the Sky-Watcher EQ6-R PRO SynScan Mount I want to get my hands on one before Christmas?

Hi All.

I have been using a QHY8L camera and I want to upgrade, my scope is a Celestron C11 which I nearly always use a F6.3 reducer on. I chose the QHY8L as it has a large Pixel size which suits my C11. 

After many hours of research my  2 options at the moment are the Atik acis 2.4 with a  pixel size of 5.8 um or the QHY10 which is 6.05 um pixel size can anyone suggest  an alternative  cooled OSC camera with a pixel size of 5.8 or greater at around the £1,500 price point?

thanks

Hi All.

I need the brass worm gear for my old school EQ6 has anyone got one knocking around or can anyone point me in the right direction to a replacement supplier.

Thanks all.

Hi All.

I'm trying to work out if my QHY5L-II Colour  will make a better guide cam than my currnet guide cam the original QHY5 (older shape black) or do I need to purchase a new mono for guiding?

If anyone can throw any light on this it would be much appriciated (sorry)

Celestrons site saying 5.475  im using a SCT camera adaptor, the standard 'Celestron' adaptor

Just tried the SCT - T2 it fits the camera. Not sure if this will need an extension tho. Going to try to get focus tomorrow.

Would I also have to extend to achieve focus?

Hi All.

Can anyone tell me what adaptors I need to attach a QHY8 onto a Celestron C11 OTA (non edge)

Many thanks.

Hve you tried these?

Hi All.

Im looking at getting a CCD camera, OSC/used, I have about £700.00 budget.  Im am wanting to target mainly galaxies. I know mono is more sensitve and I will one day go this route when I can have a perminent OBSY.

I will be using a C11 with a F6.3 Reducer on EQ6 Pro. 

Is there any other kit I would need with the CCD filters/Etc

If it was your £££ what would you put it on?

Nearly all gone just the eyepiece and guide scope rings left open to offers.

I also have a SW ALT AZ handset controller and DC stepper motors  inc gears and board from an EQ6

I agree right click on installer and select run as administrator.

Check in the 'device manager' you will find it in 'control panel' system. With the adaptor plugging in look for the entry in the list. As Spikey has stated it will be called 'prolific' if you see this in the device manager check there is no issue with it. If all is well in the device manager go to the eqascom telescope control panel>configure and hit the search button this will scan all com channels for a connected device.

Here is my Celestron C8 XLT  for sale, as I have upgraded to a C11.

I have used this for the last 4 years, It has a Telrad adaptor affixed to the Tube and a second Vixen style dovetail bar. Which I use for my ST80 guide scope.

I bought the scope with these modifications already in place I have never used the Telrad adaptor so cannot attest to its condition but the second vixen dovetail I have used to attach a ST80 OTA as a guide scope. this has always been sturdy with no issues. I used ADM Clamps.

I have posted a few more bits and bobs I am also selling so please have a look as there is a dew shield and Bahtinov mask which fit this OTA.

There are the usual marks on the dovetail bar used to mount the scope and the odd small scratch/chip here and there as you would expect but all the important stuff still works really well.

I am looking for £450.00 Any questions please ask. I would prefer collection but I can post at buyers expense.

Thanks.

NOW SOLD

Help.

I have broken my red dot finder base! I cannot find a replacement anywhere. does anyone know where these can be found?

I have done this myself to my EQ6 mount, its a bit fiddly but as I remember the Mod kit came with very concise easy to follow instructions. Give it a go your-self I think you will be surprised how straight forward it is to do.

Hi I will find out this evening and post a link here if they provide drivers for windows 10

Just plugged it into a Windows 10 PC and the camera installed using Microsoft LifeCam studio driver, no download needed. The label on the camera cable states Microsoft LifeCam studio.

Image taken 30/10/17 Celestron C11 (f6.3 FR) with EOS 1000D (Non - modded) ISO 100 1/25 Exposure.

Have ignored the Moon for ages, this was fun.

Thanks

hi there.  Could you possibly give a little details regarding spec for the Microsoft Lifecam please. I assume the picture with the altair filter is what you're selling?

Will it work on a Windows 10 machine?

Thanks
