Here's a beautiful target in Taurus - a small planetary nebula formed from a rapidly-orbiting (4-9 day period) double star system, the progenitor of which was originally about 4.5 solar masses.  The bright central star is an AO III giant, whereas the progenitor is a now a small O-type, sub-luminous dwarf. 

 

This planetary was discovered by William Herschel in 1790, and it caused him to reconsider his hypothesis that all nebulae were clouds of unresolved stars.  It is about 800 light-years from us.

MJ,

 

Nice capture. The one thing I notice is that I have a feeling it is heavily clipped since the background looks to be completely black and you have zero star color. The faint stuff below (to the right in your image) also appears colorless.

Hi all:

I started collecting data on NGC 1893 (also IC 410 and Sh2-236), the open cluster and complex emission nebula in Auriga a few weeks back. Then a few days ago I noticed that comet c2020 M3 ATLAS would be passing through the field on 12/8.

Here's the field before the comet arrived:

After many months of Covid and other problems with Software Bisque, and with Al Acker's help, I finally got one telescope working in Building 2, where I'm partnering with Tally O'Donnell.  It is a PlaneWave CDK14 on an ME II mount, sitting side-by-side with an Officina RH 350 AT that still has alignment issues.  Here's one of my first images with the PW - LRGB using six 600-sec unguided subs for each filter and binning 2x2 on a ZWO ASI 6200M camera.  The scope still needs collimation tweaks, but I'm taking data anyway and hope to post more soon.  Seeing and SQM reading are so much better at DSNM than where I live (near Boulder, CO), that I can't help but be excited for imaging endeavors with all of you in New Mexico.

Re: First Light - M33

Thanks Mike. Our remote setup supports a fullframe image circle and so we installed the 6200mm. At home I have a scope with smaller circle and I planned to use a 2600mc. As an osc, it probably wouldn't be too efficient from backyard. So the upcoming mono version looks much more promising. 
Both 2600mc and 6200mm darks are very clean. stddev from the master dark is fairly small, at gain 0 as well as at the unit gain.

2600 seems to have the same pixel size. Is the concern more for the fov and the file size?

Re: First Light - M33

Chen,

  They both have the same pixel size, but the 2600 is a 26MP versus the 6200 is a 62MP camera (hence the 26 and 62 in the model numbers, yes I just noticed that).  The file size on the 2600 is going to be around 50MB while the 6200 is around 120MB per image.  So teh 2600 helps with file size; however, it is a smaller FOV (same per pixel resolution).  Here is an example of the FOV, using my ED80mm telescope.

Re: First Light - M33

Michael - Yes, it's wise to do that unless it cause you to under sample.  My PlaneWave scope has a focal length of 2563 mm, so the 3.76 micron pixels on the 6200 each subtend 0.3 arc sec.  I figure typical seeing at DSNM is 1.5 - 2.5 arc sec.  By binning 2x2 I reduce my resolution to 0.6 arc sec.  That's good sampling for 1.8 arc sec seeing or greater (min 3 samples per object point spread function).

I’m assuming the CMOS camera doesn’t do on chip binning. I think these all do it in the driver. Are you doing it there or in processing after the fact? I’m guessing the drive would allow for creating smaller files right away versus loading each 120MB into a stacking program.

Dan - I bin before downloading, so my binned files are 30 MB in size - much better!  With CMOS  binning you get noise from two read cycles vs. just one cycle with CCDs.  But read noise is so low on the CMOS chips that it doesn't matter. At DSNM sky noise is the dominant noise source on CMOS images, not read noise or dark noise.

Dan - Yes, it is a great camera.  High bit depth, large full-well, low noise, small pixels.  Only problem is large file sizes (120 MB).  I've ordered the color version to try on the CDK14 - even with OSC operation I will not be under sampling (1x1 binning).

MJ,

 

Looks great.

 

Happy with the 6200M?

After many months of Covid and other problems with Software Bisque, and with Al Acker's help, I finally got one telescope working in Building 2, where I'm partnering with Tally O'Donnell.  It is a PlaneWave CDK14 on an ME II mount, sitting side-by-side with an Officina RH 350 AT that still has alignment issues.  Here's one of my first images with the PW - LRGB using six 600-sec unguided subs for each filter and binning 2x2 on a ZWO ASI 6200M camera.  The scope still needs collimation tweaks, but I'm taking data anyway and hope to post more soon.  Seeing and SQM reading are so much better at DSNM than where I live (near Boulder, CO), that I can't help but be excited for imaging endeavors with all of you in New Mexico.

MJ,

 

Yes… filesizes… And I’ve heard they can be hard to get square with such a large chip. I’m not going to even mention the cost of filters (Chroma’s went up something like 70% or more overnight).

 

I’m assuming the CMOS camera doesn’t do on chip binning. I think these all do it in the driver. Are you doing it there or in processing after the fact? I’m guessing the drive would allow for creating smaller files right away versus loading each 120MB into a stacking program.

 

I’m debating on a 6200 or the 2600 when the mono is available.
