As I make observations about galaxies, I predict the Galaxy Type according to Hubble's Tuning Fork (see below) before I check out what the program's data says.
I estimate the position angles of galaxies before I look at the program's data. I'm pretty dismal estimating the PAs for barred spirals.
The same is true for the Trumpler class predictions. I estimate what they are before I look at the AL data.
To earn the Southern Herschel 400 certification, you must observe all 150 objects on the Southern Supplemental Target List as well as at least 250 objects from the original Herschel 400 list (for a total of 400 observations). Each observation must include: the object name, date and time (either local or UT), latitude and longitude where viewed or imaged, seeing and transparency (not needed for imaging), instrument used, power, and a description. If you use imaging include information on the camera and settings used.
The 250 traditional northern H400 targets were completed when I did the H400 visually. A link to my visual Herschel 400 log (Certificate #506 on 2014-01-25) can be found here.
The 150 entries below on the southern list are in AL# order and were imaged using the Chile and Canary Islands telescopes of Slooh. The two Chile Slooh telescopes are located at the La Pontificia Universidad Catolica de Chile (PUC) Santa Martina Observatory @ 33.269 S & 70.534 W at 4756 feet elevation. The Canary Islands telescopes are located at the Slooh Canary Islands Observatory Institute of Astrophysics of the Canary Islands (IAC), Izana, Tenerife @ 28.29970 N &16.50826 W at 7783 feet elevation.
See the Slooh Scope tab above or click here for more information on Slooh locations, scopes, presets, and weather/sky condition descriptions.
Image formats and post-processing:
Slooh saves images in two formats: fits and jpgs. Slooh calibrates, stacks, and adjusts gamma based on the preset before saving the image as a jpg. Fits are calibrated, and saved but not stacked. All scope/cameras take single LRGB frames. (see the Slooh information tab for more details)
I used the Slooh-provided jpgs whenever possible and resorted to fits files only when image issues occurred (bad tracking, filter wheel failure, mechanical problems).
The images of the targets were post-processed with Levels, Curves, and Astronomy Tools in my old version of PhotoShop to bring out more detail. I used Noise Ninja to reduce noise in the images. My PhotoShop skills are limited.
When I think it would help see the target better I've zoomed in to make the FOV smaller in a duplicate image. The zoomed image has an unknown FOV. Zooming is does come with a cost. The Chile One scope delivers a 1336x890 pixel image with a FOV of 31x21 arcminutes. The Chile Two scope delivers a 1365x1365 pixel image with a FOW 43x43 arcminutes. Both these scopes deliver images that will look best on a laptop or computer screen and don't have enough resolution for zooming. Some of the zoomed pictures are going to look pretty rough with lots of noise. The bottom line is that big, bright targets are going to look pretty good. Dim, small, less than 5 arcminute targets are going to suffer.
Note: I'm very red/green colorblind so any colors below are probably not what normal vision people see. They look great to me!
In all images below North is Up and East is to the Left.

An edge-on spiral galaxy (Sb) with a PA of 40 degrees and a bright core. Further to the right about 1/2 way to the edge is the much smaller NGC 131. The distribution aaround the core looks thicker below and to the right. Since 134 is on the Arp-Madore list it has possibly interacted with 131 in the past.
I like the 5-star X below and to the west.

The tiny, fuzzy dot in the center of the image. Can you pick it out? I had to plate-solve the image to find it. It is the small non-double star below the center of the picture. It is so small I can't see any detail. Two nice pairs of double stars above it.

Oh well, a Google site crash lost the next five descriptions. I'm sure they were better than my second try.
An open cluster loosely spread out east-west at about 80 degrees. There is no central concentration and the many stars are (boom, another crash) spread out east-west at about 80 degrees. There are many stars of different brightness and possibly a bit of faint nebulosity in the center region...Trumpler III3rn....that time it worked!

This is just above (N) of the Running Man and it is easier to see if you leave him out. A medium number of stars of different brightnesses with no clearly defined center. I don't see any nebulosity although being that close to the Running Man and M42 I wouldn't be surprised for there to be some. Trumpler II3m

This is a combination emission and reflection nebula. The embedded stars cause the surrounding gas cloud to both give off and also reflect light. It is pretty impressive and looks like a baby rosette nebula with a ring and dark center. I wonder if the open clusters in the area were formed there.

At first I thought this was the small grouping in the top right of the image. Looking at SkySafari showed that NGC 2546 is really 70 arcminutes in size so it is huge (70 arcminutes) with the image only capturing part of it. No matter the size it is spread out, should have many stars, and those here are not all the same in terms of brightness. Trumpler III2 r.
