Photometry

I tried to estimate the supernova brightness. I tried to analyse 2 FIT files:

SN2004et, 03.10.2004 (01:14 - 01:23 UT)
Resolution: 1.32 arcsec/pixel
Camera: SAC8 at prime focus
Telescope: 8" F6 Orion Europa Newtonian
Result focal ratio: F6
Filters: Multiband Moon & Sky Glow Filter
Exposure: 93x4s (gain 100%, HiRes, Amp On), DF and FF applied
Capturing: K3CCDTools 2.1
Processing: stacked in K3CCDTools 2.1 and saved to FIT
Object altitude: 34
Conditions: temperature 9.2C, 65% humidity
Seeing: stable
Transparency: soft haze, Moon phase 80.3%, mag limit ~4mag
SN2004et, 03.10.2004 (00:36 - 00:55 UT)
Resolution: 1.32 arcsec/pixel
Camera: SAC8 at prime focus
Telescope: 8" F6 Orion Europa Newtonian
Result focal ratio: F6
Filters: Multiband Moon & Sky Glow Filter
Exposure: 115x8s (gain 100%, HiRes, Amp On), DF and FF applied
Capturing: K3CCDTools 2.1
Processing: stacked in K3CCDTools 2.1 and saved to FIT
Object altitude: 38
Conditions: temperature 9.2C, 65% humidity
Seeing: stable
Transparency: soft haze, Moon phase 80.3%, mag limit ~4mag

Analysis was performed in TeleAuto program. Reference stars are marked by red circle, measured star is in the green circle.
Here are the results:

Exposure: 93x4s
Reference catalog: GSC 1.2
Exposure: 115x8s
Reference catalog: GSC 1.2
Exposure: 93x4s
Reference catalog: USNOA
Exposure: 115x8s
Reference catalog: USNOA
Exposure: 93x4s
Reference catalog: USNOA, GSC 1.2 (for star GSC4246.1036,
which had probably incorrect magnitude 14.0 in USNOA catalog)
Exposure: 115x8s
Reference catalog: USNOA, GSC 1.2 (for star GSC4246.1036,
which had probably incorrect magnitude 14.0 in USNOA catalog)
