NGC4438 : The Eyes Galaxies Field with G4-16000

[floastro]

Hi guys,

This is the first lights of my ASA 12"N f/3.62 (purchased in 2007) with my Moravian G4-16000 CCD camera using one KAF-16803 chip of 36mm x 36mm (4K x 4K).

The adjustments, collimation, ASA OK3-Z pression screws, asked a lot of attention.

For a precise collimation, i use the CATSEYE XL & XLKP kit.

This is the first 3hrs of exposures taken the last weekend in one night. The second night was too windy unfortunately.

That is absolutely amazing and definitely a standard to aspire too.

An amazing look of a spectacular view field with delicate details.

 

Question:the CCD acquisition informations are collected in a database software or its just a (let's say) excel sheet formatted?

Thank you so much. Optimized this instrument with a huge CCD chip is very hard, but after a lot of effort the results arrive. I wait a clear sky to continue this image and to take the RGB frames.

About the CCD Acquisition information, i created it with MS Word. Here in France, several amateurs has created similar things but not clear to me. I created mine with the essential information.

 

Thanks once again.

The full 4k res version really is a stunner.

Have you tried catching the M87 jet? Could show up well at this focal length, although I think you may require quite short exposures to prevent it from getting lost in the core.

Thank you all ?

I hope to continue this image and to take short exposure to see if i can show the M87 jet. Of course i keep you posted about it.

Thanks.

This is one only 5min. of sub exposure processed.

Can you confirm that is the M87 jet ?

Looking at this APOD the orientation is correct, although one of the images appears to be flipped. Great job.

Wonderful result and a tremendous setup.

Where are you in France? I'm in the south east, 05.

Hello Olly,

Thank you. ?

I live in the Loiret (45). I am 5km of Pithiviers and 40km from Orleans, 90km from Paris.

My G4-16000 is optimized for my Televue NP101is for large fields. Now, i optimize it for my ASA Newtonian.
