M104 - unguided

jenchris (Jennifer) · #1 03-05-2011, 10:00 AM

I've taken a few shots of M104 and DSS'd them not expecting to get a lot of detail.

This came out better than I'd anticipated so I thought I'd humbly present it for scrutiny.
I'm only beginning to get the hang of this stuff so I'm quite pleased that I got an image at all.

40 approx x approx 30sec ISO 800 and 1600 mixed
8 darks

Isn't it great what you can capture using short subs!
You've got to be really happy with that one Jen.

Well done and keep practising. Its a thrill to get images that are good.

Congratulations Jennifer. Always pleasing when you get a nice surprise like that putting your data together.
I can recall seeing a B/W pic of this one in a text book from the 70s, and thinking at the time WOW! It was done with a massive reflector and film, but yours is right up there with it.

Why unguided? (given you have OAG)

Unguided because my guide camera is not working....

Round stars, tiny object and 40 seconds unguided is very very good.

Greg.

Thanks guys - I tried a similar run the next night and got an awful result - worked out that if the battery is really topped up, I can get superb tracking with no problems - battery more than one day off the top and it's ordinary!
Might go for a bigger battery (7a/h at the moment) and get more stability - I have a deep cycle 38a/h that will fill the bill quite well!
