Hi all,

 

As I had another clear and cold night ( that is beneficial for the uncooled camera ) I tried

on IC410, the Tadpoles.

Due to full moon I really wanted to use the L-Extreme filter but that filter on this camera

somehow does not work as well as on my 1600MCC. ( still not known when it comes back

from repair ).

So in short, I used an UVIR filter with some fear because of the very strong moonlight.

Since I mounted the baffle tube extension on my RC8 this would be a nice trial to

see if the straylight problem would be less.

So here goes, IC410, the tadpoles closeup.

They do not stand out very well since this is OSC under full moon shrug.gif

Setup as usual RC8, CCDT67 and 224MC with UVIR filter.

269 frames of 40 seconds.

According to ASTAP the limiting magnitude on a single frame was 14.3 which

is quit astonishing under full moon with this uncooled camera and 40 second exposure.

 

Clear skies,

Mert

I see 'em Mert!

 

I hope you get your main camera back soon but it looks like the 224MC can do some decent work while you wait!

 

OSC and a full Moon...you don't take the easy road do you...lol!

Thanks John, I apreciate that!
It's not the same with an uncooled camera giving this small FOV.
But it's the best I have right now so I'm quit happy I can at least try to image some.
At least on this sensor I can't see the straylight problem so that might have improved with the baffletube extension.

At least from a processing standpoint of view it is an improvement. Processing 263 frames is blazing fast ( small filesize ) :smirk:

Hi Peter,

 

YES it's cold, normally the temperature is much higher but I have to admit

we are in winter time now.

Maybe I can get out again to my favorite dark site soon however I don't

seem to locate an adecuate object yet for this combo of RC/APO and the

224MC.

Maybe some tiny ARP galaxy from a dark site would be fun to try!

I've gone extreme last night to point to the full moon and see what happened.

The image is not so sharp but at 1 frame, 0 gain and 0,001 second

this is what my RC delivers with this big central obstruction contrast

is not like the APO or my Maksutov ( now on another site )

Just for laughs here is the ( part ) of the full moon I shot.

I know, it's not DSO shrug.gif
