JUPITER from last Sunday night

[Robert_T]

Finally getting round to posting something from my last run Sunday night. Wasn't going to bother for they were a very poor lot indeed. This ones the best of 'em. Seeing was pretty ordinary. Waht stuffed me though was I accidently left the Lymax cat-cooler running for an hour and a half (prob 20min would do it) and I reckon it it never cam near ambient temp after that.

Here tis - 4 iterations of LR at 1.2 curve radius.

cheers,

Nice one Rob - softened a tad by the seeing, but nice colours and details none the less.

Cheers

Still nice Rob, good saturation of the GRS!

Very nice shot Robert,

Man look out everybody when the seeing improves, cause you got heaps of detail there already. It'll be sharper then.

Watching the performance of the 900nc very closely.

Hi Robert. Very nice shot.

I'm not sure I understand the bit about leaving the cooler in too long...it's not possible to get the mirror below ambient by using ambient air...?

I use mine for at least 3-4 hrs.

I'm confused..

Hey Asi, that makes sense... I'm just going on the comments of a few others and web-site explanation on the coolers that running too long can be not a good thing. I dunno, can moving ambinet air bring a surface to less than ambient compared with outside tube

cheers,

Well I'm no expert, but I would have thought it was near impossible to get to ambient using ambient air...unless the temp stayed put for several hours, Otherwise there would be no discussion on using peltiers & active cooling on an SCT...

Anyway, I'm not sure what the go is now lol!

Sorry for getting off topic....Ummmm, yes....Lovely picture there Robert!

I can remember when people used to go ape when they had a hint of detail within the GRS. Now its just accepted as par for the exercise.
Anyway nice shot

[davidpretorius]

the seeing has been atrocious apart from mike's last night. Gee jnr is getting close

I have been meaning to ask you, how do you rate the neximage to the 900nc??

also the boys have been busy re raw mode etc

Thank's a lot Martin !!!

Unfortunately, i have no SPC900 to test this new version, but as soon as the feedback is good, i'll upload the new version on my
website, because there is a lot of people waiting for RAW mod on the SPC900 )))

Objet : [TWIRG] more serious now - BETA of WcRmac renewed and WcRacc
question


Hi,

Now for the more serious - here a BETA of the renewed WcRmac
which supports the SPC900 on its own (as SAA8116 cam)

<http://www.burri-web.org/bm98/stuff/wcrmac-2.0.85.zip>

Changes:

******* WcRmac V 2.0.85 *********

WcRmac should now detect if another application
is streaming and complain if not.
The detection of the camera is newly done based on the
USB Vid and Pid for the known models. If an unknown cam is
found WcRmac tries to find out if it can support it or not.
The SPC900NC should now be identified properly

- Added: A third Tab to display the major tuning parameters
- for informational purpose only and ReadOnly
- Added: detection of a streaming application
(an application using the cam in streaming/preview mode
is required for proper operation)
- Improved: detection of attached cameras

I've tested Vesta and ToUCam but again it is beta so take care....


Question - does anybody still need WcRacc and if shall I leave the I2C
support in which I've done once my cam could not be saved through USB - it
goes via a serial port ???
(a circuit diagram of the RS232 to I2C could be added though)


Feedback here or direct to me

Cheers

Martin

Hi DP, many thanks for the link, I've downloaded the beta version, might get a chance to try tonight if the cloud moves along.

The spc900nc has the edge on the Neximage. There's not a hell of a lot in it, but it's definitely less noisy so gain can be pushed more.

Yeh Red jnr and GRS are closing fast, looks to me like it might be ships passing in the night though rather than a head on?

cheers,
