Jan14 Beginner DSO Winner - Magellan!

Ok heres my first submission with my christmas present from Santa. A Canon T3. I am still seeking accessories for my telescope but just too cold to set everything up.
The photo is taken on a tripod, unguided. ISO-1600, 300mm lens at f5.6 4sec exposure. Modified in photoshop to add duplicate layers or what I understand to add darks.
Here is my contribution.
This is taken on Christmas night, in a public park in central Tokyo. Intolerable light pollution. I took 20 x 300s light frames with darks, bias, and flats, for a total of 100 minutes of integration.
Equipment is as below:
- Kasai Trading Blanca 70ED
- Astronomik CLS-CCD filter
- Astro-Tech 0.8x focal reducer and field flattener
- Canon T-ring
- Canon EOS 600D, self-modded
Mount is iOptron ZEQ25GT on Benro 3580T photo tripod.
Guiding done with the Kwiq autoguider packages (50mm scope and QHY20.
Main errors during this session:
- spacing from back of flattener/reducer to camera sensor is too short. Around 55mm, should be 85mm
- dithering in Backyard EOS was set to level 1. With this type of focal length, I want level 4 or 5. Therefore noise stacked up...
- It is really really cold in a public park at night I had prepared myself hot tea, but forgot it!

M45_31x120s_1hr2m_ISO1600_Final by AstroJeff, on Flickr
Here is my submission for the month. Not a lot of integration time to work with and had to resist that temptation to overstretch, I think it turned out well. I always have had an issue with bright reflection nebulae. I even caught Meropes Ghost in this data. Normal processing washes it out but its in my Flickr a few down. I hope you all Enjoy:
