| AT 2022vxe (Cygnus) AT 2022vxe (Type: YSO?) discovered 2022-09-24.523 UT by Gaia Alias: Gaia22dzx Brightening in candidate YSO Alerting Magnitude 12.34 ( vs historic mag 12.65) ( TNS 2022vxe, Gaia22dzx ) |
| AT 2022vxe - 2024-08-25 (T+701.4d) Image below (2024-08-25.902) was taken 701.4 days after discovery of 2022vxe Position of reported transient (distinct, faded from T+42.4d) is shown by white cross-hairs Measured magnitude +11.99 (Clear Filter) |
 |
| Annotated CCD Image (100% size, linear scale, cropped) 3 x 90s exposure (average combine), 3x3 binning, Clear Filter 2024-08-25 21:42 UT (#1232007-09) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2 |

| CTB1 (Cassiopeia) Alias: Abell 85, LBN 576, SNR G116.9+00.1 [ Supernova Remnants ] |
 |
|
Annotated CCD Image (70% size, square root scale) 3 x 180s exposure (average combine), 3x3 binning, Clear Filter 2024-08-25 22:16 UT (#1232013-16) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2 |
|
CTB1 - Negative Image An arc of nebulosity is visible in the image. (this is consistent with a bright section of the SNR shell- see reference image) |
 |
| Negative CCD Image (70% size, square root scale) Image details as above |
|
CTB1 - Earlier Image (2024-08-17) No indications of any nebolosity in earlier image of CTB1 which is consistent with its near central position which misses the brighter shell. |
 |
| Negative CCD Image (70% size, square root scale) 5 x 180s exposure (average combine), 3x3 binning, Clear Filter 2024-08-17 00:38 UT (#1229052-56) 12" LX200R (at f/10.4) + ST-10XME Auto-guided using TS 80mm APO, ZWO ASI178MC & PHD2 |
| CTB1 - Reference Image
(Negative) FOV of image(s) above are indicated on the reference image by black rectangle and confirms that the faint nebulosity in CCD Image above corresponds with the shell-like feature in the reference image. A longer exposure is still required in order to improve S/N |
