Al, thanks for the follow up. Wasn't able to catch the show. I've heard that people have been able to use a MC Micro-Ex for autoguiding. That said I suspect it has more to do with the particular frame grabber. Do you think you might give it a shot and see if it matters which camera is used?

Curtis-

 

Not sure I will get a chance as its supposed to be cloudy tonight.  If I get a break in the clouds I will try and see if PHD or Metaguide can work with either Micro of DSO, using one of my different frame grabbers.

Al, thanks, look forward to the report and/or show. From what I've seen metaguide is the software reported to work. This would be very good for whichever camera works (likely both do) since I'm guessing it could also be used as a finder at the same time. If this does work then I would happily buy one of these cameras over a QHY5L. Right now I have a straight through finder ready to go, but if it doesn't come to focus I can always modify my Celestron Firstscope little dob OTA, in fact I'd prefer to be 100% reflectors. :dobsonian:

Al, thanks for all the info here on these cameras.

I had also thought the Micro was not capable of using color when 3D-DNR was active. I thought it might even be due to turning on AGC. However, with some help from Rock I have tweaked the settings to get color with the Micro when 3D-DNR is used. For more info, see my post at...

I also made a comment on that link.

 

The key take-away is that: in videocam MENU's AGC (Automatic Gain Control) setting,

although the user can set OFF, LOW, MEDIUM, or HIGH (which are just different max. gain cap values),

it is the camera's DSP ultimately determines how much gain it will apply to the incoming CCD image sensor signals.

 

In another word, AGC setting is just your "wish", while camera's DSP may do something else based on other factors.

 

Manual Gain Setting, if a videocam has that feature, would be more desirable.  

In photon starvation shooting conditions, e.g., videoing/imaging deep space, we know sometimes camera's own intelligent exposure control does not always work out.

This is almost universally true for P&S, DSLR, mirrorless, and videocam, if "Auto" (on exposure and gain) is used.

 

Clear Skies!

Just to add an interesting point:

 

What is AGC OFF?

Hint: it is not gain = 0 (which means the picture will always be black), nor gain = 1 (means no gain and no loss).

 

When the AGC is OFF, the gain is set to a factory default value (I think it a very low gain value.)

 

If memory serves, Samsung SDC435 does not use the "AGC OFF" term but "Manual Gain" when gain is not in any flavors of "AGC cap" settings.

When Manual Gain is chosen, a slider can be called out for the user to adjust and lock down the gain value permanently (until the setting is once again changed by the user.) 

 

Hey too smart the DSP may not be the best thing.

 

Clear Skies!

Al,
 
Thank you for buying both cameras with your own money and performing this objective comparison. It is great help to the entire EEA community.



Ditto.

Having cameras available in this price range is a plus for anyone looking to get into Video Astronomy. And the more info that can be provided to foster their use the better.

A quick note to those testing these "LN300 style" cameras (just my opinion) side by side, make sure the Brightness and Gamma is the same on both...and that the video frame grabber settings are the same for both (as well as same reducer, etc).

 

Regards,

Both are based on the LN300 which has been out of production for months.  Only one vendor, Mallincam, bought large volume of inventory before they were gone.  The other vendor is notorious for taking money and not delivering. 

 

An alternative is the new OCT Revolution2 camera.  It is PAL which is much better.

If can be bought for $99 if you ask for CN special.

OCT Revolution2 "CN special" is $99 for; camera, c-mount adapter, and UTC hand controller.

 

I highly advise you do a search on this forum before sending money to a vendor.

Most vendors are honest, but some are not.

Charles has given you good advice on considering the R2 which is the newer version of this camera.   You can purchase a 'kit' which includes monitor and and other accessories for $299   or you can purchase just the camera itself for $99 if you mention you are a member of Cloudy Nights.

 

see here:  http://www.revolutionimager.com/

 

email the vendor here:  [email protected]

 

Note:  Mallincam is also a very reputable vendor.    If you can get a PAL version of the Mallincam Super Micro it will perform as well as the Revolution imager, but i believe the cost of the Super Micro is $179  so as Charles says in the prior post, the $99 value for the Revolution R2 camera is a very good value.

Mallincam has stock of MicroEX NTSC, and might have PAL versions too.

OCT in link above is well regarded and has Revolution2 in stock.

Either could ship to UK.

This thread should give you some background and some posts in it may enlighten you.  One of the posts I made contains a link about AVS substituting a camera in place of the DSO. 

 

I suggest you pay VERY close attention to the Terms of Agreement for AVS.  You have no protection.

If you import an astronomy camera into the UK directly from a vendor located in a non-EU country such as the US or Canada, you are going to get hit with taxes and duty from UK customs and excise, and probably a fee from the post-office or courier for handling the taxes. I would therefore not recommend buying directly from a non-EU vendor for these reasons. You might want to check if any of the cameras you are interested in are available directly from a UK or EU vendor/distributor as the duty and taxes will already be incorporated in their list prices. Alternatively, you could look at buying something like one of the USB GPCAMs  from AltairAstro in the UK. They are probably one of the most economical options available in the UK.

 

Edit: Did a quick check and unfortunately I don't see any EU based distributors for the US/Canadian cameras mentioned in this thread, but perhaps I missed them.

Mallincam's world wide shipments are handled by their US distributor -

 

Jack's Astro Accessories
Jack Huerkamp
(985) 863-2165 (Office) or (985) 445-5063 (Mobile)
[email protected]

 

Jack regularly ships cameras to the UK, it's very straight forward.

 

I'd take a good look at the analogue video cameras, the Mallincam Micro EX and the Revolution R2 from OCT. Errol make s a great suggestion about the cameras from the UK based Altair Astro.  Altair carries entry level USB digital video cameras. Mallincam carries both types.

 

While there are many other sources for entry level cameras those three sources are all known for good customer service and their knowledge of the EAA type of observing.

A small UK vendor is AVC.  They sell a LN300 type camera here.   I know nothing about AVC other than link.

I have not heard of these cams are they suitable for imaging like the other mentioned cams ???  and ya right I just had a look at them and they do seem to be decent budget cams

Would you go for mono or colour, baring in mind I am new to astro-imaging that's why I ask and I will email the above see what they says as this is going to be my first attempt at it I am going for a budget one to begin with

I know that I am straying off topic (sorry) by discussing the Altair Cams in this thread, but I believe they are well suited for imaging from their specs. I don't own one though. As an example, the newer IMX224 GPCAMS are based on the same sensor used in the ZWO ASI224, which I did own and that sensor is used successfully for EAA by a number of people. In addition, Altair GPCAMs are compatible with SharpCap software, and I remember seeing a video of Robin, the developer of SharpCap, demo'ing the software on one of their cameras - can't find the video at the moment. Perhaps you could join the Altair- Astro google group, where I am sure you could get answers from users of these cameras. In addition, you could start another thread on these cams if you wish.
